Cellulose insulated walls are more fire resistant than non-insulated walls. This is because cellulose's dense structure keeps the insulation from melting (as fiberglass does) when temperatures reach above 350 degrees. Cellulose installed by R-Tek Insulation is treated with specially engineered and highly effective fire retardants that actually slow the spread of fire. The final result is that our cellulose insulation provides 15 minutes of burn resistance to 2x4 wood framed walls.
FIBERGLASS VS. CELLULOSE
Cellulose can be blown into every nook and cranny in walls, crawlspaces and attics with ease and accuracy. Because it creates a seamless seal, the amount of air flow is reduced drastically, so temperatures are more consistent and noise reduction is greater from room to room and from outside to inside the structure.
