Cold weather and home heating are never far away for us living in the Calgary / Airdrie area, conversely home cooling in the summer months can also prove challenging. Heating and cooling account for 50 to 70 percent of the energy used in the average home. If your home is un-insulated or under-insulated, you’ll spend extra money on your heating bills trying to maintain comfortable temperatures. Insulating an attic delivers the greatest return on investment for most Alberta homes. As ENERGY prices rise, it means deeper applications of attic insulation make more economic sense. Adding house attic insulation can prevent gradual damage to your home caused by heat and moisture. It prevents water vapor from seeping in and eroding your walls/ceiling. It also slows down heat buildup in your attic, which can cause the shingles on your roof to swell and crack.
