                                                   Attic Insulation And The Benefits of Attic Insulation


No matter the season or region, attic insulation is now a major part of any house in Canada. When your home is not energy efficient, keeping it warm or cold in seasons can be costly and uncomfortable for you and your family. You don’t have to compromise on comfort — even on the hottest or coldest day of the year. Attic insulation is an excellent way to protect your home from temperature extremes and moisture damage. It is also an effective way to reduce heating and cooling costs. It acts as a barrier to prevent the transfer of heat from the inside to the outside of the house in winter or heat from the outside to the inside in summer.


R-Value & Materials

Attic insulation ranges in effectiveness, so to help people find the best insulation, industry professionals typically refer to its effectiveness with R-value. R-value is a measurement of insulation’s resistance to the flow of heat. The higher R-value of a product, the more effective it is at reducing energy costs in your home. Attic insulation can be constructed from a wide range of materials, including cellulose, fiberglass, mineral wool, liquid polyurethane, and polystyrene.


Our trained attic insulation experts will visit your home to inspect your attic space and make energy-saving recommendations. The evaluation will include a review of insulation thickness, ventilation, air leakage and provide an array of cost saving solutions. Contact us to schedule your free attic insulation estimates!

Roof or attic insulation as well as other types of insulation in buildings is an important factor to reduce unwanted heat loss and also reduce unwanted heat gain. A perfect attic reduces both energy loss and energy costs. They can significantly decrease the energy demands of heating and cooling systems. One thing more must be added; it cannot completely prevent heat or cold losses, but it can minimize it.
