In an average home, about 50 to 70 percent of energy is used for cooling and heating alone. Your energy consumption can be even higher without proper insulation in areas that need it most, like the attic, walls, floors, basement and crawlspace. The attic, in particular, is a place of interest as it is where dependable Toronto insulation can drastically lower your energy usage and expenses.
Insulation
By definition, insulation is any product that reduces heat loss or heat gain by placing a barrier between spaces with different temperatures. In most homes, insulation is used to prevent air flow changes inside the house. Proper insulation effectively traps the air and stops it from escaping, limiting air movement. There are different types of attic insulation in Scarborough, each with a corresponding R-value.
What is R-value?
The R-value measures resistance to heat flow. The higher this number, the better the insulation a material provides in extreme cold or heat. Installing insulation with the highest R-value is ideal for attics as well as the access door. You can always check if your attic has enough insulation by hiring a contractor to measure it for you and to determine which type of insulation works best for your home.
Batts and Rolls Insulation
Batts and rolls, also known as blanket insulation, consist of flexible fiber sheets made of mineral wool and plastic or natural fibers that are can be fitted to the spacing of wall of wall studs and attic floors. This costs less than any other type of insulation and, through the use of chemicals, can have flame-resistant properties.
Loose-Fill Insulation
Usually made of fiberglass, rock wool, or cellulose, loose-fill insulation is blown using special pneumatic equipment. This material is ideal for use in attic, wall cavities, unfinished attic floors, or wherever it is difficult to install other types of insulation.
Rigid Foam Insulation
Rigid foam insulation is very efficient in exterior wall sheathing, interior wall sheathing for basements, and for attic hatches. With R-values ranging from R-4 to R-6.5 of thickness, this material is at least twice as effective as other materials, making it worth every dollar.
