Pictograph of how Spray Foam Works

Here is Why Foam Applied by Therma Seal is Best

Icynene Spray Foam Stops Air Leakage

Spray foam insulation is like a warm windbreaker jacket — it stops the cold air from passing through.

Fiberglass and cellulose insulation are like a wool sweater - if there's any breeze, it doesn't keep you warm. Even if they're very thick to give an extremely high R-value, they'll still let air leak out of your home and increase your energy bill.

Spray Foam Insulation for Homes is a Modern Material

Spray foam insulation is a modern material that's been used for over 25 years.

Fiberglass is an old technology, and cellulose is little more than shredded newspaper. So modern types of insulation are becoming more popular.

Spray Foam Fills Gaps

Spray foam insulation expands up to 100 times to fill gaps — ensuring maximum insulation.

Fiberglass and cellulose are extremely difficult to install perfectly — the spaces that are left add up to the size of a basketball in the average home — leaking enough air to fill two blimps each day!

Icynene Spray Foam Insulation Protects Your Home From Water

image021
Many open cell spray foam (such as Icynene LD-C-50) drains water rather than holding it, and most closed cell spray foam doesn't let it in at all.

Cellulose is made from shredded newspaper, and drinks up water. Fiberglass batts and cellulose don't repel water — the water stays in place and may damage your home as well as reduce how well the insulation works. This is one of the leading contributors to mold development — and it also decreases R-values, meaning you spend more on energy.

Spray on Foam Stays in Place

Spray foam stays in place – it doesn’t settle or sag, vertically or horizontally. It moves with the house as it settles. Spray foam insulation is completely solid when it sets, doesn’t produce any dust, and doesn’t let dust or other pollutants pass through to your home.

Fiberglass and cellulose settle and sag over time, leaving gaps that compromise insulation.
Fiberglass and cellulose can be dusty and allow dust and other pollutants to enter the building.

Icynene Spray Foam is Healthier

Many spray foams (such as Icynene LD-C-50) don’t contain formaldehyde, HCFCs, HFAs, or HFCs, and doesn’t give off harmful emissions once installed.
Most fiberglass contains formaldehyde, and may emit formaldehyde fumes into your home.

Spray Foam Doesn't Attract Pests

Many spray foams do not provide a source of food for rodents, termites, or other nasty critters. As a home insulation, spray foam also doesn’t make for good nests.
Fiberglass and cellulose can be torn apart by pests, and some even use them for nesting.

Spray Foam Isn't Easily Damaged

Spray foams harden to a dense material that isn’t easily damaged.
Exposed fiberglass and cellulose are easily damaged – insulation in areas such as basements and attics may be compromised by cats, children, moving boxes around, and other general usage.

Importance of creating an air barrier in an unvented attic

Creating an air barrier in your unvented attic can lead to serious savings in energy costs and create a healthier living environment for you and your family.  Basic insulation provides R-value, which is the materials ability to slow down heat transfer across a membrane such as a roof or attic deck.  This R-value helps with heat conduction but does not prevent the accumulation of heat by convection, which is air passing through cracks, crevices, and other openings of an attic trying to create equilibrium between the house temperature and the outside heat and elements.  The cold air being pumped through your vents is constantly being sucked into the attic and leaked into the atmosphere.  With Therma Seal's Icynene Spray Foam System you can reduce energy costs by creating R-value but ALSO eliminate heat build up through convection.  Any cold air pumped into your house would be encapsulated within your house and attic without any waste.  You wouldn't go to the beach with a cooler of ice and not put the lid on it right?!  Contact Therma Seal Insulation Systems at 561-775-9703 or visit our website www.thermaseal.net for more information about our energy saving solutions.
