Insulation Comparison

Use this as a tool to compare types of insulation. The experts at MT Insulation will guide you through the process from consultation to installation, and everything in-between.



Icynene spray foam stops conditioned air from escaping your home and keeps unwanted air out. Like a windbreaker, spray foam stops cold and hot air from passing through your exterior walls.
Fiberglass and cellulose operate more like a woolen sweater, allowing the air to pass through. Most fiberglass insulation has a foil or paper backing that when installed, will be closest to the direction of warm, conditioned air. This decreases the flow of air and moisture, and stops fiberglass particles from littering the living space.

Cellulose insulation is plant-based and used to be made from natural materials with low-thermal conductivity like hemp, straw, and cotton. Today, cellulose insulation is commonly made from recycled newspaper and is treated with chemicals to reduce the potential of ignition. 
Certain types of spray foam, such as open cell spray foam, expand up to 100 times its original size to completely fill every corner of your home’s envelope for total insulation and air sealing. This makes it easier to fill small nooks and crannies. closed cell spray foam does not expand.
It’s hard to perfectly install fiberglass and cellulose without the help of an expert. Any spaces and gaps that aren’t filled can equate to the size of a basketball, with enough air leakage everyday to fill two air blimps!
There are a few different types of spray foam insulation and each handles water differently. Open Cell foam is not water resistant or waterproof. Closed Cell foam is water resistant. For a water resistant and waterproof product, consider High-Density Closed Cell foam.
Traditional insulation drinks up water, staying in place to potentially damage your home as well as reducing the functionality of the insulation. It’s also a leading contributor to mold growth!
Spray foam stays in place and does not settle or sag ensuring total continual performance.
Gravity leads fiberglass and cellulose to settle and sag over time diminishing its performance and compromising your comfort.
Spray foam’s air sealing qualities help reduce the amount of dust, allergens, and pollutants entering your home, protecting you and your family from allergies.
Fiberglass and cellulose can be dusty and allow dust and other pollutants to enter your home which can trigger allergies and respiratory issues like asthma.
Many spray foams do not include harmful components that hurt the environment, making them safer to have installed.
Most fiberglass contains formaldehyde, and may emit formaldehyde fumes into your home.
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 nests.
