Effective spray foam insulation slows the transfer of heat into and out of your home, reducing your energy bills. It keeps the air in your home warmer in the winter and cooler in the summer. It can also help reduce noise levels and improve indoor air quality. Depending on your climate, and R-value standards, the cost of insulation can be paid for by energy savings within just a few years.
All insulation is measured with an R-value, which represents how much resistance to thermal flow it provides. The higher the R-value, the greater the insulation’s effectiveness. Insulation is made out of materials that have low conductivity, meaning they don’t allow the transfer of heat easily. Metals are excellent conductors because their atoms are very close together, while materials like fiberglass have pockets of air between the fibers and are less dense, making them poor conductors.
Insulation does not stop the transfer of heat altogether, but rather slows it down so it takes more work for your heating and cooling system to keep your house comfortable. This can extend the life of your system, save money and help to combat climate change.
Don’t Overlook the Attic: Hidden Energy Savings
The most common form of insulation is known as blanket insulation. It is available in rolls or batts and consists of flexible fibers, most commonly fiberglass. It can also be made of mineral (rock and slag) wool, plastic fibers or natural fibers such as cotton and sheep’s wool. Blanket insulation must be properly installed to ensure it has a good R-value. Moisture can decrease the insulation’s effectiveness by increasing convective heat loss, so it is important to air seal a house before adding more insulation and to regularly inspect insulation for compression, gaps and moisture problems.
