Insulation is essential for comfortable indoor temperatures and energy savings in home construction and renovation. We offer various types of insulation, including fiberglass, cellulose, spray foam, and rock wool, each with its pros and cons. Fiberglass, used widely, comes in batts or rolls made of woven glass fibers for warmth. Cellulose, from recycled newspapers, goes in walls and attics. Spray foam, expanding plastic, excels in tight spaces, and rock wool, from natural rock, blocks sound well. Choosing the right type of insulation involves considering factors like budget, installation time, and energy efficiency.
