Spray Foam Insulation and Energy Efficiency
Heated and cooled air can’t stay in a home or building forever, but there are a lot of ways to reduce your energy bill, and keep your home at comfortable temperatures. This source, and many others, show that most energy loss occurs:
- through the roof
- through windows
- through gaps around the door
- through the walls
- through the floor
Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles. Heat energy also leaves the house by radiation through the walls, roof and windows.
Based on what we know about heat/cool air leaks in a house, spray foam insulation can provide some great solutions for energy efficiency. Spray foam insulation helps to seal gaps in the roof, walls, corners, and between windows/doors. Your investment in spray foam will not only reduce your utility bills, but will also keep you comfortable in your own home!
