Attic Insulation Installation Seattle

While the DIY approach is often cost-effective, it’s not recommended for installing attic insulation. To ensure optimal protection, it’s crucial to seek expert installation for your attic insulation. Attempting to do it yourself may lead to problems with foam layers, mold growth, or even personal injury and attic damage. Call Guardian Home for expert attic insulation.

Seattle Spray Foam Insulation

Polyurethane foam insulation is created by combining isocyanates (known as the A-side) and polyol resins (known as the B-side) through a chemical reaction. When sprayed from a foam gun, the substance expands and fills in crevices and gaps in your attic or crawl space before hardening. This insulation material is highly efficient for sealing attics and crawl spaces.


Typically, fiberglass insulation comes in batts that can be rolled or placed on various surfaces, such as walls, floors, or ceilings. Nowadays, blown fiberglass is increasingly in demand and has become a significant aspect of our insulation work. This specific type of insulation is produced by combining recycled glass with natural sand.


The insulation known as cellulose is crafted from recycled paper, typically newsprint, with an exceedingly elevated recycled content of about 82-85%. The paper is reduced to minuscule fragments in the manufacturing procedure, transformed into fibers, and then combined with a flame and insect deterrent. The most common retardants utilized are mineral borate or ammonium sulfate. Blown-in pellets are the primary form of cellulose insulation, but it can also be created in batts.


Cotton has gained popularity among eco-conscious individuals. Its creation involves repurposing recycled blue jeans and other natural cotton fibers from industrial waste. Typically, cotton insulation consists of 85% recycled cotton and 15% plastic fibers, which are treated with boric acid for flame resistance. This type of insulation is non-toxic, and its installation doesn’t require respiratory or skin protection. In contrast to fiberglass insulation, there are no reported incidents of skin irritation or burning from contact with cotton insulation.

Benefits of Clean Insulation

Clean attic insulation can result in lower energy usage because it regulates temperature better than old insulation. Heating and cooling systems don’t have to work so hard or run as often, which translates into lower energy bills. 

Clean insulation also helps prevent the buildup of moisture inside the attic. Moisture buildup leads to mold and mildew growth which can cause a home’s structure to decay. Mold and mildew also affect a home’s air quality.
