Insulation Contractor is a critical part of your home’s ecosystem, optimizing temperature, humidity and air quality. Insulation slows the flow of heat and keeps conditioned indoor air from seeping out, saving energy. It also contributes to quieter living spaces and extends the life of HVAC equipment by reducing the workload it must perform to keep your house comfortable.
Insulation materials are rated by their thermal resistance, or R-value. Higher R-values are better at reducing heat transfer, which can help reduce your heating and cooling costs. The type of insulation you choose depends on your needs and climate, as well as your budget and energy-efficiency goals.
The Science of Heat Control in Attics
Some of the more common types of attic insulation include cellulose, fiberglass and foam boards. Cellulose is a soft, recycled paper material blown into walls and attics in a blanket form. Fiberglass is available in a wide range of thicknesses and forms, including batt or rolled insulation and loose-fill. Rigid-board insulation consists of foam panels that are cut to fit between joists and sealed together with spray foam or caulking. Foam insulation has a high R-value but is not flammable, making it suitable for fire-rated attics.
To make the most of your attic’s insulation, proper air sealing is essential. Look for signs of leakage, such as discolouration of the attic drywall or plaster, around chimneys and plumbing stacks, and around pot lights and electrical penetrations. You can seal these leaks yourself using a two-part spray foam kit or by hiring a professional contractor.
