Do I Need To Insulate The Attic Floor Of A Pitched Roof?

do i need to insulate the attic floor of a pitched roof

In most homes, the ultimate goal of insulation – above and beyond energy efficiency – is to maintain year-round, comfort for the rooms below. As a result, we insulate the floor of the attic to optimize comfort in the main living areas. If we insulated the underside of a pitched roof, we’d be risking heat gain and loss between the adjacent rooms below and the attic space, compromising the home’s energy-efficiency and comfort. In this context the decision regarding attic floor vs. roof insulation is no-contest. The floor wins every time.

Insulating the floor is standard practice for an unfinished attic space. The exception to this rule takes place when families opt to convert an unfinished attic space into something usable or livable.

Insulation And Your Pitched Roof

Insulation needs changing if the attic space becomes livable

If the attic is a livable space, meaning you’ve converted it into an extra bedroom, a study, a man cave or a family game room, the insulation needs change. Now, in the attic floor insulation vs. roof insulation conversation – the roof insulation is the priority.

If you’re planning on converting or remodeling an attic space, we recommend visiting our post, Converting Attic Space to Livable Space: How it’s Done.

PLEASE NOTE: In order to be considered a livable or usable attic spaces, building codes require that the ceiling height be 7.5-feet from the for, for at least 50% of the finished square footage. Homeowners aiming to convert their attic into living space may need to renovate the roof, lifting/extending it by a couple of feet or more, to accommodate a finished floor, the insulation requirements, and finished walls and ceilings.

Always visit your local building department, and bring plans or existing measurements of your entire attic perimeter (length, width, height at multiple points along the walls or niches), and speak in person with one of their building inspectors. In an effort to keep attic dwellers safe, there are stringent rules and building codes pertaining to attic conversions, especially in older homes where rewiring or updated plumbing may be required for the project to move forward. It’s always best to complete a conversion or remodel by the book or you risk jeopardizing resale value down the road.

Insulate the attic floor if possible

Whenever possible, do insulate the attic floor, underneath the subfloor and final flooring materials. This is the best way to conserve energy in the main part of the home, especially if the attic is on its own zoned heating system or if it’s used infrequently and its cooler/warmer temperatures negatively impact the rooms below. Heat continues to rise, and move into cooler pockets, so failing to insulate the attic floor may result in higher heating and cooling demands for the rest of the home – particularly during peak hot/cold seasons.

If sound transference is a concern, focus on using cellulose, fiberglass, or foam insulation, as they are the best for mitigating sound between spaces. This may require removing and replacing old, dilapidated or outdated insulation.

Insulate the pitched roof and exterior walls

You’ll also want to insulate the exterior walls and the underside of the attic’s roof. Otherwise, space will suck up a tremendous amount of heating and cooling energy throughout the year, because all of that energy goes right up and out of the roof. Depending on the age of your home, you may also need to install an interior roof lining to protect the attic space from water, dust/debris, and weather damage.

Along with your new attic insulation, the attic roof also requires ventilation or else you’ll wind up with moisture control issues. Most insulation contractors – and your building department – will require that the converted roof space incorporates adequate attic ventilation and may also recommend a vapor or moisture barrier to further prevent moisture damage, including the development of mold or mildew.

Work with a licensed contractor before installing attic roof insulation

We highly recommend consulting with a licensed contractor before installing roof insulation in your attic. First and foremost, you want to make sure you actually need it, and that you aren’t wasting money, time, and energy. Secondly, insulating and finishing a ceiling and roof in a converted attic space often requires additional considerations – such as ventilation, replacing seals on any roof penetrations, and potential electrical work if the wires are old or if new electrical work is required.

The safety and energy efficiency of your home depends on doing the job right, and it’s always good to get the nod of approval from a licensed contractor, even if you plan to do the bulk of the work on your own or with the help of construction-savvy friends. The last thing you want is to fail your final inspection and have to start over again, or to wind up with a major leak or fire as the result of inexpert workmanship.

When Is The Best Time Of Year To Insulate Your Home?

when is the best time of year to insulate your house

Your attic insulation provides year-round protection from heat gain and loss, especially during peak times of the year. If your attic was never installed in adequate quantities or quality from the start, older insulation has broken down and no longer works, or the insulation has been damaged or removed destroyed as the result of pest infestations or water damage, you need to update it.

The question is, when is the best time to insulate your home? Busy schedules and the quick passage of time can mean losing the ideal opportunity to replace or update your home’s insulation in time to reap the cost-savings benefits.

Fall And Spring Are Ideal Seasons To Insulate Your Home

Updating or replacing insulation is best done during the more moderate seasons when your HVAC system is powered off or only working at bare minimum levels. That way, licensed insulation contractors can provide a thorough inspection, estimate, and services before it’s critical for your whole home comfort and utility expenses.

Here in the Bay Area, spring and fall are the best times to inspect and replace insulation as needed. That way, your home is adequately insulated in time for the peak heat and cold seasons. Upgrading your insulation before the year’s highest- and lowest temperatures mean you gain instant savings benefits from your new insulation.

Energy.gov’s Energy Star page cites that adequate insulation that meets the Energy Efficiency guidelines and R-Values for your region, combined with proper air sealing, can save you as much as 20% on your utility bills each month. In almost all cases, necessary insulation replacement pays for itself via energy savings within a handful of years or less.

Signs Attics And Crawl Spaces Need Insulation Replacement Or Updating

First, don’t forget that your crawl spaces – as well as your attic – should be evaluated when determining your home’s insulation needs.

If you know what you’re looking for, you can conduct your own DIY insulation to determine whether or not your home needs an insulation update or full-blown, insulation replacement. You’ll need to enter the crawl space under your home, and then take a good look at the insulation in your attic as well.

Signs that your home’s insulation needs repair or replacement include:

Energy bills seem higher than usual

If your energy bills seem higher than usual, and there haven’t been any notable changes in your programmable thermostat, inadequate insulation could be the culprit. Also, make sure you’re observing your HVAC manufacturer’s schedule for maintenance.

The age of your home

If the insulation is original, your home is on the older side (15 to 20-years old or more), and you haven’t had your insulation inspected in a while, you’ll probably benefit from supplementation. Today’s insulation is superior to the products manufactured even 10 or 15 years ago. Not only have energy efficiency standards evolved in the past couple of decades, but insulation quality becomes compromised over the years by moisture, mold/mildew, movement of humans or rodents on top of it, etc. This means that older insulation is almost always in need of updating, amendment, or a full replacement.

History of pest infestations

The large majority of insulation found in Bay Area home is batt-style (like puffy blankets of insulation) and spray foam insulation. Both types are very attractive to pests, which burrow into it or chew it up for nesting material. In addition to posing a health risk, the quality of insulation is diminished, and insulation won’t work as it was designed to. Any evidence of pest infestations or damage should be handled and cleaned up immediately, including the replacement of damaged insulation.

Moisture or water damage

Major leaks, burst pipes or other sources of water damage can instantly damage insulation. However, a chronic presence of moisture – even seasonal dampness – eventually leads to mold, mildew, and/or the inevitable breakdown of the insulation’s compounds. Once the cause of the water or moisture damage is identified and repaired, professional insulation installers can clean up the mess, remove the damaged insulation, and replace it.

The house feels drafty, then insulate your home

All of a sudden, you’re experiencing drafts that don’t seem to be coming from the typical exterior door and window culprits. This is another sign that old or damaged insulation is no longer serving as the buffer between exterior walls and your interior rooms. Once old batts are replaced, your home’s interior temperature will be more consistent from room to room.

Update Or Replace Insulation In Your Bay Area Home

The fall season is a great time to update or replace insulation in your Bay Area Home. We recommend scheduling a consultation with at least two to three different contractors to learn more about what your house needs, to get a competitive estimate, and to get a feel for which company feels like the most trustworthy and qualified team for the job.

The team here at Attic Solutions has decades of experience under our belts, and we pride ourselves on being honest, hardworking, and dependable. Contact us to schedule a consultation and determine whether it’s the right time to insulate your home.

Why You Should Insulate Your Crawl Spaces

why you should insulate your crawl spaces

Insulation is a key player in your home’s energy system. Sufficient, geo-specific insulation can reduce your home’s energy spending because it reduces heating/cooling costs. When you consider that 40% to 70% of a home’s energy consumption is directed towards heating/cooling – air sealing and insulation becomes a significant priority.

Crawl Spaces Need Insulation Too

Most people understand the need for insulation in the attic and exterior wall spaces, but they often forget that insulation is necessary for crawls spaces as well. These wide-open spaces – many of which are ventilated – can act like heating/cooling vacuums when they aren’t adequately insulated.

There’s another reason why crawls spaces require insulation: moisture control. Many crawl spaces are susceptible to the moisture or condensation that occurs due to fluctuations in temperature and humidity – or water that collects below and around the foundation. If your ventilated crawl spaces are insulated but don’t have the right moisture barrier in place, they provide the perfect environment for mold, compromising your home’s structural integrity and negatively impacting indoor air quality.

If your home was built before the 1990s, we can almost guarantee your crawl spaces require an insulation upgrade if one hasn’t been done already. If you live in a home that is 20-years old or less, it’s still worth a peek underneath the house and any additional crawlspaces to establish whether your crawl spaces are insulated or not.

Signs Your Crawl Space Insulation Needs to be Replaced

Here are some of the most common signs indicating the insulation in crawl spaces and other locations needs replacing or an update:

  • Your heater is on, but your feet are cold
  • Energy bills are going up – even though you’re HVAC is regularly maintained, and your thermostat settings haven’t changed
  • Humidity levels are going up
  • Evidence of mold
  • You’ve taken a peek and notices it looks flat, shredded, spotty or dilapidated
  • There is evidence of water or pest damage
  • Odd drafts in your home that don’t seem to align with window and doors
  • You know the insulation pre-dates 1990

Any of these signs mean it’s time to schedule an inspection from a licensed, insulation contractor who can let you know what – if any – crawlspace insulation modifications are necessary.

There’s a Difference Between Ventilated and Non-Ventilated Crawl Spaces

Not all crawl spaces are created equal, and knowing what you’re dealing with ensures you insulate them correctly.

Insulating ventilated crawl spaces or subfloor crawlspaces

Some are ventilated, which means they’re vulnerable to moisture and are typically found underneath the floor of your home. In addition to the insulation, you’ll want to seal any gaps or air leaks from electrical, plumbing, venting, or other penetrations in the subflooring. As long as you’re underneath the house – or in the crawlspaces – use the opportunity to insulate air ducts and plumbing pipes to further optimize efficiency.

Then, install a vapor (moisture) barrier between the exterior and interior crawl space surface, before adding the insulation, to keep inevitable moisture from seeping through.

Non-ventilated crawl spaces

If a crawl space isn’t ventilated, you’ll only need to insulate the walls, rather than the subfloor above.

Additional Tips for Professional-Quality Crawl Space Insulation

Here are additional tips for obtaining professional-quality crawl space insulation:

  • Use a licensed insulation contractor. Hiring a licensed insulation contractor with a reputable reputation ensures the job is done thoroughly and complies with current energy efficiency/building codes and guidelines for the Bay Area climate.
  • Eliminate any water or moisture. If there is water or moisture evident, eliminate it and/or dry the space completely before proceeding. SmartPipe Systems, crawl space-specific sump pumps, and drainage matting designed for dirt floor crawl spaces are all helpful for keeping the bulk of underground water or moisture from accumulating in the space.
  • Install water- and mold-proof insulation. Fiberglass insulation batts are still a standard because they’re the most affordable in terms of first-time costs. However, if moisture is at all an issue, invest in higher-quality, water-resistant insulation options, such as spray foam, ridge board or cellulose. These products are more durable and efficient – which means they’ll save money in the long run.
  • Address any maintenance issues you notice. If there are signs of structural damage or obvious repairs, stop and address those first.

DIY Insulation Jobs Are Not The Ideal

While insulation can be installed in DIY fashion, it’s not recommended. Firstly, insulating attics, walls and crawl spaces isn’t an easy task, and it takes non-professional contractors far longer that blogs or YouTube videos may indicate. Replacing insulation also requires a level of agility and physical ability (not to mention tolerance for small, enclosed spaces) that a DIYer may not have or be able to sustain. You may wind up spending money – and hours – attempting the feat, only to cease the project and hire a professional anyway.

Installing crawl space insulation also requires protective gear, finesse, and specialized equipment to help the work go smoothly, and to not make a mess. Finally, with a home repair as essential to whole-home energy efficiency, moisture control and indoor air quality as updated insulation is – it’s essential that the job is done right. Otherwise, all that time, energy and cost will have been wasted.

mold in air ducts

The Hidden Dangers Lurking In Your Air Ducts

Are you a neat freak? Do you clean the house on a regular basis?

Keep at it—that’s actually a great thing! After all, dust and debris can easily trigger coughing, sneezing, and other symptoms.

Don’t just clean the floors and call it a day, though—there are other areas that you be cleaning as well. Take the air ducts, for instance, allergens can easily build up, which can make you sick.

Mold in air ducts is an issue as well. As you can imagine, that can significantly impact your health in various ways.

But wait, how can you tell if your ducts need cleaning? Want to know? Then be sure to read the rest of the post—we’ll be going over everything that you need to know below!

How Often Should You Clean Your Air Ducts?

As a general rule, you should clean your air ducts every three to five years. Why? That’s how long it takes for the ducts to fill up with grime after a thorough cleaning.

Keep in mind, however, that this time frame does not apply to everyone. How often you need air duct cleaning will depend on various factors such as how often you use the HVAC system and where you live.

Do you or someone else in the house have asthma or allergies? If so, that’s another reason why you should clean the vents more frequently.

How Can You Tell If Your Air Duct Needs Cleaning?

You can tell whether or not your ducts need cleaning by looking at them. Is there any noticeable debris on the outside? Are there “poofs” of dust near the vents?

If so, you’re probably overdue for a cleaning.

It’s also a good idea to clean them if you notice a vermin infestation. After all, the critters may be entering and exiting through the ductwork.

Mold in Air Ducts: Why It’s a Problem

Mold is a common issue with air ducts. This makes sense when you think about it—after all, condensation easily forms along the vents (more on this later).

As it is, this poses a major health risk. For one thing, it can lead to various symptoms such as sneezing, cough, and watery eyes.

There’s also toxic black mold to worry about. As implied by its name, this variety releases toxic spores that can be detrimental to our health. In severe cases, it can cause nausea, vomiting, chronic fatigue, and persistent headaches.

The worst part is that the spores can easily spread to other areas of the home via the ducts!

What Causes Mold to Form in the Air Vents?

It’s not uncommon for mold to grow in your HVAC system. After all, there’s plenty of moisture and condensation.

For instance, water vapor from the air conditioning can easily make its way inside the vents. Assuming that humidity levels are high, the moisture will not be able to evaporate—instead, it will stay in the ducts.

As you can imagine, that would facilitate mold growth. Over time, the colony will grow bigger and bigger as it feeds off organic materials.

How to Tell If There’s Mold In the Air Ducts

Assuming that there’s mold in your air ducts, the first thing that you’ll probably notice is a pungent odor—something that resembles old gym clothes. It’s hard to miss!

You can also tell by checking for visual signs. Grab a flashlight and peer inside the vents. Do you notice any irregular splotches? If so, it’s probably mold.

In severe cases, mold can grow outside the ducts and onto the wall. If that’s the case, call a professional right away as the problem may be too difficult for you to handle yourself!

Last but not least, examine the vents for standing water. Remember, mold thrives on humidity—if there’s moisture in the ducts, chances are, there’s mold somewhere.

What to Do If You Suspect Mold

It can be quite challenging to remove mold from air vents. For one thing, you can easily inhale the spores when you’re doing the cleaning!

Given that the infestation is mild, however, it is possible to remove the mold yourself. Most of the products that you’ll need can be found at your local home improvement store.

Generally speaking, however, it’s much better to just call in a professional—they’ll be able to remove the mold from your home quickly and safely.

Other Contaminants in Air Ducts

Aside from mold, other contaminants can build up in your ductwork. Take dust and dirt, for instance—these particles can easily become airborne. In other words, there’s a great chance that they can get sucked into the ducts!

Another thing that can accumulate is dander. For those of you who don’t know, it’s a material that’s shed from the body of humans and animals. In large amounts, it can exacerbate allergies and other respiratory conditions.

There’s also a chance of pests in air ducts. After all, the vents are a conduit for warm air in the winter and cool air in the summer—that makes them the perfect nesting spot for critters!

Keeping Your Air Ducts Clean

Hopefully, that gives you a better idea as to why mold in air ducts is an issue.

When in doubt, call in a pro—they’ll be able to identify and solve the problem for you! Remember, your health is worth it.

radiant barrier

Radiant Barrier: Is it Right for Your Home?

You live in a warm climate and your cooling costs are outrageous.

Did you know that the sun is the primary source of heat in your attic space?

Did you know that a radiant barrier can keep your attic cooler and reduce your cost to cool the whole house?

Not sure what a radiant barrier is? No problem. Keep reading to learn if a radiant barrier is the right choice for your home.

What is Radiant Barrier Insulation?

A radiant barrier is a type of insulation specifically designed for attics in warm to hot climates. The barrier is made from a highly reflective material.

Types of Radiant Barriers

Radiant barriers come in a few different options. It is always a reflective material, usually aluminum foil, adhered to a backing material for support. This stiffer material may be cardboard, plastic, OSB, or sometimes kraft paper.

You can find reinforced radiant barriers for increased durability. Fiber-reinforced backing is easier to handle during installation.  

Radiant barriers may be installed as part of your attic’s insulation system. 

Perforated vs Non-Perforated Barriers

You can find both perforated and non-perforated radiant barriers.

A non-perforated barrier does not allow water vapor to pass through it. It is a solid piece of reflective material.

Depending on your HVAC system and house ventilation, this may not be good. It can cause dampness in the attic. If moisture from the house cannot find another way out, it can condense in the attic space and damage your home.

A perforated barrier has tiny holes that allow for better airflow. This reduces the risk of condensation forming. 

How Does a Radiant Barrier Work?

Radiant barriers physically reflect the sun’s heat, called radiant heat. By doing this, they don’t allow the attic infrastructure to absorb the heat.  This is the reflectivity of the barrier. 

It keeps the joists and ductwork from getting hotter. Think of it as moving your home from the direct sun into the shade.

They also keep the air in the attic space from heating up. This is the emissivity of the barrier. Essentially, the hot air from the outside is not able to emit heat to the cooler air on the inside.

What are the Benefits of Radiant Barriers?

In a nutshell, radiant barriers reduce heat gain from the sun and reduce cooling costs.

By reducing the amount of heat your home absorbs, you can significantly cut down on cooling costs. If you aren’t running your HVAC system at its max, you will likely also save money in the long-run. You will reduce maintenance and repair costs for the system.

The hotter it gets, the better your radiant barrier will work. This means that in the worst part of the hot months, you will reduce your cooling costs the most. 

A radiant barrier allows your attic space to be converted into a living space. You can keep the attic a comfortable temperature all year long. 

You can finally convert that unused space into your dream home office or guest room!

Radiant barriers may also help you qualify for Energy Star certifications for your home. This helps with resale value. 

How is Radiant Barrier Installed?

A professional should install the radiant barrier.  

It is generally installed during construction of a new home. However, if you are re-roofing your home, or you have an unfinished attic with open rafters, you can retrofit the attic with radiant barrier.

The foil is draped between roof rafters. This can be accomplished before the roof goes on, or by stapling the material to the bottom of the rafters after-the-fact. 

It’s important to allow the material to droop between the rafters. There should be about 1″ of air space between the radiant barrier and the bottom of the roof. 

Things to Watch Out For During Installation

A radiant barrier’s effectiveness depends on proper installation. Using a certified installer is your best bet because there are some precautions to be taken during installation. 

Aluminum foil conducts electricity. The installer needs to make sure that the foil does not contact bare wiring or other sources of electricity. 

The barrier should not be installed on top of the attic floor insulation. Foil on the floor will accumulate dust. It may also trap moisture in the thermal insulation. Both reduce the effectiveness of the radiant barrier and can cause other expensive damage to your home. 

The radiant barrier requires the right spacing to function properly. If the foil is pulled tight between rafters, or is sandwiched between pieces of insulation, the foil will become a conductor of heat. 

The air space is what makes the foil work as a radiant barrier. No air space means that the barrier will actually be working against your insulation system. It will reduce your thermal insulation’s effectiveness. 

Is a Radiant Barrier Worth the Cost?

The value of a radiant barrier in your home depends on your climate and current insulation system. You benefit the most when:

Your Attic is Poorly Insulated

If your attic is already very well insulated, you won’t notice the difference of the radiant barrier.

The older your home, or the worse the condition of your current insulation, the more difference you will see. It may be more cost effective to upgrade your insulation with radiant barrier than remove and replace all of your insulation. 

Your Roof Gets Direct Sunlight

A radiant barrier reduces the heat gained from the sun. If your home is in the shade consistently, the radiant barrier won’t be as effective. 

A south-facing roof will see the most benefit from the installation of a radiant barrier. 

Outbuildings with metal roofs would also see a huge difference in radiant heat absorption. If you have a garage, barn, shed, or other outdoor workspaces, you can cut the summer swelter by adding a radiant barrier. 

There is Ductwork in Your Attic

Most older homes have ductwork that runs through the attic. A poorly insulated attic means that the hot ducts warm the air as it passes through the attic into your living spaces.

This makes your air conditioning system less effective. 

Adding a radiant barrier to your attic will reduce the heat absorbed by the ductwork. It reduces the load on your HVAC and A/C systems. 

Installing a radiant barrier is cheaper and easier than insulating the entire ductwork system. 

Get Ready to Cut Your Cooling Costs

Living in a warm climate should not mean you have to break the bank to keep your home cool. 

A radiant barrier may be the perfect solution to keeping your home and wallet more comfortable in the heat.

attic insulation cost

Why an Attic Insulation Cost Is an Investment in Energy Savings

Ready to start saving up to 50% of your home’s power bill? It could be as easy as outfitting your attic with insulation.

To get started, you need to look at the attic insulation cost and how it compares to your potential savings. Those in warm climates will save when keeping their home cool while those in colder climates will save when keeping their home warm.

Insulation stops the flow of heat and air through your attic. Ready to learn more about how you can save by investing in insulation today? Then keep reading!

Get an Energy Audit

Before you decide whether or not you need insulation, get an audit. This will give you a good idea as to where your home stands when it comes to energy efficiency.

Signs You Need Insulation

Even before your audit, if you see these signs then you most likely need insulation in your attic. The first of these signs would be ice dams.

Ice Dams

Ice dams happen to homes that are in colder climates. You’ll see ice building up on your home’s eaves in winter. This ice will damage your shingles and roof.

These ice dams happen because you are heating your home and that hot air escapes through the roof. The hot air melts the snow, and the melted snow runs down the roof. This water then refreezes into those ice dams.

Temperature Changes

You have the air or heat running, yet you notice the temperature changing as you walk from room to room, this is a sign that your attic is not properly insulated.

You are spending too much money trying to evenly heat or cool your home. If you insulated your attic, then your whole system will get a break.

Drafts

If there are drafts in your home, that’s likely cold air from your attic. You need insulation to stop this movement of air.

High Energy Bills

Talk to your neighbors and ask them what their average energy bill is. If you find that yours is significantly higher, you may have an insulation problem.

R-value

When buying insulation, you’ll see that it is rated with an R-value. This is the material’s ability to prevent the flow of heat.

The higher the rating, the better the material is at preventing the flow of heat. Don’t fall into the trap of thinking a double layer of insulation means double the R-value.

It doesn’t work this way. The insulation needs to be a single layer for it to effectively work as intended.

You need to use the climate zone map to know what R-value level you should aim for when you buy insulation. For example, if you’re in the warm climate of zone 1 then you can use insulated rated as low as R30 for your attic.

While if you are in a cold climate in zone 7, for example, then you’ll want insulation rated as high as R60 for your attic.

Types of Insulation

There are three main types of insulation for you to choose from that will be effective in insulating your attic.

Batt or Blanket Insulation

This is the insulation that people typically think of when they talk about insulation. It consists of large rolls of fibers that are held together with a paper backing.

These are best used when your attic is large. It doesn’t work so well in tight spaces. If your joists and studs are a standard distance apart, then you’ll be able to unroll these into the spaces with no problems

R-Value

Insulation batts come in four main types of materials: fiberglass, cellulose, mineral wool, and cotton. You’ll find that the R-values range from 2.9 to 4.3 per inch.

Loose Fill or Blown-in Insulation

This type of insulation either comes in large bags of loose fill to be spread around or a professional installer “blows” it in by a machine. This is perfect for filling small or unusual spaces.

You’ll find it in the same variety of materials of batts including fiberglass, cellulose, and mineral wool fiber. This should be your first choice if your attic is older and already has insulation or is an awkward space.

R-Value

The R-value varies depending on which type of material you choose. It will generally range from 2.2 to 3.8 per inch.

Spray Foam Insulation

There are two types of spray foam to choose from: open and closed cell. The open type is the cheaper option but doesn’t provide a barrier to vapor. The closed cell option is more expensive and denser.

The great thing about spray foam is that when your installer sprays it, it sticks to whatever surface it is aimed at. This is a perfect solution for the ceiling of the attic.

R-Value

This type of insulation has the highest R-value ranging from 5 to 6 per inch. This is an important consideration if you live in a more extreme climate.

Attic Insulation Cost

The cost of your insulation installation entirely depends on the size of your attic, the amount of material needed, and the type of insulation you choose. As a general guideline, pricing can range from $1.50 to $3.50 per square foot.

If you decide to have a professional install the insulation, you’ll also need to factor in the cost for their services.

Start Saving Money on Your Home Heating and Cooling

If you are looking to save money on your energy costs you need to give your attic a check. If you see that you either have no insulation or it’s old, then it’s time give your attic an insulation update.

Don’t let yourself be deterred thinking that attic insulation cost is too high. Investing in the insulation now will translate to a more comfortable home and big savings on your bill.
