Cellulose insulation is made from recycled paper products treated with fire-retardant chemicals. Its dense composition makes it eco-friendly and effective at reducing air leaks. Fiberglass insulation, on the other hand, is made from fine glass fibers and is widely known for its durability and resistance to moisture. Both materials are excellent insulators, but choosing between them often depends on your specific needs, budget, and insulation goals. At Peak Insulation, we can help you determine the best option for your home.
