Are There Both Pros & Cons to Having Spray Foam Insulation in Residential Homes?
Yes, kind of. We believe the many pros far outweigh the cons, read on though and judge for yourself.
- Spray polyurethane foam (SPF) Insulation is a better insulator than most other insulation options
- Its R-value is typically around 6.5 per one inch of thickness
- This is often more than double common insulation alternatives
- As it is sprayed directly into all the cracks, gaps and other uneven surfaces it is more efficient at air sealing which is one of the biggest contributors to heat loss
- Spray foam insulation also helps to keep out moisture and dust contaminants making it a great way to weatherizing existing homes and new construction
- HVAC sizing can be reduced as much as 35% without the loss of efficiency and comfort when installing spray foam insulation
- It significantly reduces drafts and noise in most residential homes
- As most gaps and cracks are sealed it can impede the incidence of entry of insects and pests
- Applied properly to areas such as the gaps between the attic and living spaces spray foam insulation can help reduce mold, mildew growth moisture and humidity issues
- Spray foam insulation can also help to resist settling and cracking issues due to its general stability and strength
- Installing spray foam insulation often qualify for utility rebates, tax credits and green certification
- The American Recovery and Reinvestment Act allows for a tax credit of 30% on the purchase of energy efficient products, up to a maximum of $1,500 per year in 2010
- In addition many local utility companies offer rebates for energy efficiency upgrades.
- Initial cost is higher
- Compared to fiberglass bat insulation and blown in cellulose insulation, the initial cost can be significantly much higher
- While it depends on the thickness of the compared insulation, on average it takes about two years to achieve the recover the initial investment
- Local building inspectors are often not fully educated in the SPF process
- This can sometimes mean that they may need to check the latest energy code
- This can slow down construction for a few days while they come up to speed
- Installers must be experienced and certified as it takes a lot more skill to install SPF than apply fiberglass or cellulose
- Installing spray foam insulation will take more time and while it is being applied no other trades can be working on the site at the same time
- In a non-new construction remodel or upgrade, home owners cannot be in the home or return to it for 24 hours after installation
Does it make sense to have spray foam insulation applied under my floor or crawl space?
Traditional crawlspaces are designed to be vented. In this type of application spray foam insulation is applied between the floor joists and directly to the subfloor sheathing. This method protects the interior of the structure from unwanted air infiltration, ground gases, insects, rodents and heat loss.
If I get spray foam insulation installed in my Los Angeles home, what kind of return on my investment should I expect?
In most residential applications the ROI averages about two years. This depends upon many factors such as the scope of work (which walls, roof basement attic areas to be insulated). Also the size of the house, type of heating system and lifestyle of the home owner. When we look at a particular home project, we can be more specific.
The ROI (Return on Investment) is the point at which savings in energy costs equal the cost of installing SPF insulation. After that, considerable additional savings are realized due to ongoing reduced energy consumption. This is true for homes that we have treated in the Los Angeles area. Homes in harsher climates can see even faster ROIs.
Actually it’s better than FREE. As most people break even with a couple of years and then go on to save between 30% – 40% on their utility bills, it really is better than free!
Will spray foam cost you a dollar investment initially? Yes of course.
As there are many factors that affect the actual installation cost the best thing to do is ask us for the free quote.
Call us at +1 (855) 226-5577 and we will be happy to provide you with a no obligation quote.
Factors that affect costs include, location, ease of access, size of project, nature of project, walls, floors, crawl spaces, attics, new construction, remodeling and much more. Note, we have a very small projects team. This helps to make the smaller projects much more affordable.
Can I have spray foam insulation applied to my roof and or attic space?
Yes, in fact there are many benefits to adding SPF to your attic space. Spray foam is applied in an attic space in a different way to how to other forms of insulation are applied. Attics with regular forms of insulation are vented. With Spray foam the attic becomes a conditioned area in the home. This fundamentally changes the nature of the roof space.
Improving the attic space in this way will usually decrease the home’s energy consumption by around 30% to 40%.
There are potentially other benefits as well. Go here for a full discussion on the merits and methods of applying spray foam to an attic.
How many inches of closed cell foam do I need to have all the benefits closed cell foam has?
Two inches of spray foam insulation is generally the most cost effective depth. All of our statistics and energy savings examples on this site are based on this depth.
My house has no insulation in the walls and the walls are finished. How do I insulate my walls?
On retrofits and remodeling projects where the sheetrock remains in place, we use Open-cell foam insulation and inject it (rather than spraying it) into the walls. The main reason for this is due to its slow reaction time (expansion phase). This helps to ensure that the cavity is fully filled.
Here are our typical process steps for injection foam insulation in existing walls.
- Using an infrared camera, we mark the walls where the studs and fire blocking is situated
- We then drill a ½” hole just below the fire blocking on every cavity
- Using a special spray tip designed for this purpose we then spray into the cavity
- The foam flows down inside the wall cavity expanding slowly as it goes. We watch the foam expand using the infrared camera to make sure the cavity is filled.
- We then patch the drilled holes ensuring the walls are smooth
Is there a smell after you apply spray foam insulation?
Once spray foam insulation is dry, it is fully inert and there are no smells or odors. However, during the drying process, the foam generates a gas that can be harmful to humans. This is why we recommend contractors and or home owners, do not enter the home for at least 24 hours after the insulation is applied.
Why should you seal off the vents in the attic when applying spray foam insulation?
When applying spray foam insulation to an attic space, it is effectively converted into part of the climate controlled area of the home. Although it is somewhat counter intuitive, this reduces the overall energy consumption of the home.
