Spray Foam Information for the Home

Fiberglass

Know the truth before you decide

Fiberglass Batts

Fiberglass has many factors working against it. Give it a few years in a crawl space and it will get wet, moldy, and start to sag and fall to the floor giving you ZERO insulation. Another factor is that fiberglass insulation is a great home for rodents and insects. Given that they want to stay warm too, mice will use your insulation to make nests and multiply in your home. Spray foam does not provide an easy home for these creatures because they cannot make a nest in it.

Labeled vs. Installed Performance

Consumer Update: Insulation Effectiveness Bulletin

Summary:

Oak Ridge National Laboratory research shows that “perfectly installed” batts lose 11% of their labeled R-Value, and that “commonly installed” fiberglass batts lose 28% of their labeled R-value.1

This study confirms tests conducted 20 years ago by fiberglass manufacturers, and reveals the surprisingly large disparity between the labeled R-value and the installed R-value of fiberglass batts. 2

Open Cell Foam

Find out if open cell foam installation is right for you

Cost- It is far less expensive than many other kinds of foam insulation, but still can achieve greater value if there is enough space in the area to be insulated.

Green- open cell foam requires less resources and materials, lending to its eco-friendliness as well as its affordability. Open cell foam is a permanent, smart, and a value adding choice for insulating your project.

Expansion Rate -Open cell foam is a water blown, high expansion product that grows up to 150 times its liquid form. The expansion ratio allows open cell foam to penetrate the smallest gaps and cracks found in existing homes and allows us to insulate and seal hard to reach areas that would not be possible with conventional insulation.

Open cell foam is an air barrier - Insulation such as fiberglass and cellulose are not air barriers. Coffee cups are insulated with foam or plastic because moisture will not penetrate these materials. Can you imagine trying to pour coffee into a cup made of cellulose or fiberglass? Please, do not try it. Spray foam insulation does not support the growth of mold even when it is exposed to water. The leak will need to be repaired but your investment will be protected when using foam insulation.

Stability -When you live or work in a smaller or older building, shifting foundations and the soil underneath can cause problems with the insulation. Open cell foam accommodates seasonal shifting, meaning the investment you make in your structure lasts for years to come instead of degrading and compromising your homes thermal performance. Open cell foam also works as an excellent sound dampening agent, creating a more comfortable home or productive workspace.

Closed Cell Foam

Closed cell spray foam insulation: The Top Shelf selection

Can be used in all areas of your home Closed cell foam can be used for both interior and exterior insulation, so all portions of your structure are covered.

All climates Closed cell foam can be applied to substrate temperatures as cold as 20 degrees to protect your home or business from the elements all year long.

Durability Closed cell spray foam can increase the racking strength of your building by 100% to 300% depending on the area applied and the thickness. Closed cell spf adds impact resistance to any structure which makes it ideal beyond your insulation needs. Closed cell foam is approved by FEMA for use in flood zones and can provide an extra level of protection from flying debris caused by hurricanes, tornadoes and hail storms.

Thermal resistance It also has one of the highest R-values per inch, even in small, narrow spaces. Closed cell foam expands up to 30% from its liquid size allowing it to penetrate the hard to reach areas almost as well as open cell foam.

Mold resistant Lastly, it is inhospitable to mold, which is extremely important. In many instances of mold, insulation is a prime habitat that promotes growth. You can avoid this invasive and destructive pathogen entirely when you select closed cell foam for your home or business.

Air Barrier – Closed cell foam qualifies as an air barrier at 1.5”

Crawl Spaces

Don’t listen if anyone say’s “it does not matter which type of insulation you choose for your crawl space”

Closed Cell Foam is the only insulation approved by FEMA for flood zones.

What does that mean to you? If you are unlucky enough to suffer water damage in your basement or crawl space you can rest assured that insulation removal and replacement will be omitted from your list of expenses if you choose closed cell spray foam for your below grade living space and the flood waters recede within a few days. (Results may vary depending on application, thickness and substrate.)

Fiberglass has many factors working against it. For starters, this picture says it all. Give it a few years in a crawl space and it will get wet, moldy, and start to sag and fall to the floor giving you ZERO insulation. Another factor is that fiberglass insulation is a great home for rodents and insects. Given that they want to stay warm too, mice will use your insulation to make nests and multiply in your home. Spray foam does not provide an easy home for these creatures because they cannot make a nest in it.

Crawl Space Before

Crawl Space After

Attics

One of the best ways to combat air leakage is to install your entire HVAC system within the thermal envelope. Often, the easiest and least expensive way to accomplish this is to move the envelope from the flat part of your attic to the slopes.

If your attic is unsuitable for storage and there is no duct work installed another slightly less expensive option would be to insulate the “deck”, or attic floor. Traditionally, this is where fiberglass is installed.

Injection or “pour foam”

For block fill or traditional framing injection foam deliverers without costly demolition and repair work. We use thermal imaging to insure the foam is installed where you need it.

If you are concerned that your home is not insulated correctly, or if you are having problems heating or cooling your home, your hvac system maybe improperly designed. Please call and request a home evaluation and one of our in-house experts will gladly assist you.
