Attic Insulation for new construction and upgrades
Insulation is important year-round. A well-insulated house will stay cool in summer and warm in winter. Roof or attic insulation is most important for keeping cool in warm weather. Most homes absorb heat through the roof, so insulating the top of the house keeps heat from reaching down to the living areas.
If your house is uninsulated or poorly insulated, you will quickly recoup the costs of insulating with lower energy bills year-round. If you are building a house, good insulation installed properly will reduce your heating and cooling needs, and save you money.

What you need to know about Attic Insulation
•The insulating properties of any material are referred to by their RSI (the metric measurement of thermal resistance) or R-value (the imperial measurement of thermal resistance). RSI or R-value is an indication of how well something resists the transfer of heat. The higher the RSI or R-value of a material, the more it will resist heat.
•Before you add more insulation to your attic, you need to know the R-value of what currently exists. Measure the thickness of your attic's insulation. For example, to achieve R-40, you will need approximately 34 cm (13.5 inches) of fibreglass blanket insulation. For R-50, you would need about
•Wall insulation is also as important to cooling as it is to heating. Wall insulation can be more difficult to add to a preexisting house than insulation in the attic, but it can be done. For more info call Maximum Poly at 306 975 9659
•Insulation materials have what is called a "settled density," which is the thickness they will retain over time. The settled density equates to the R-value. Some materials settle more than others. Most insulation retailers or contractors will know how the various materials settle and can help you decide how much you will need to install.
•Attic air circulation is also important. The movement of air will remove heat gains. One device that can do this efficiently is a solar roof fan. The fan will come on when it is sunny to remove hot air from the roof. In the winter months, you can cover it to stop the fan from removing warm air from the attic.
