Insulating a home can lower a home’s heat loss by up to 75 percent. If you live in an older home, that is not insulated, even installing partial insulation can cut down heat loss by up to 30 percent. One of the easiest do-it-yourself insulation choices is installing spray insulation.
How spray insulation works
Spray insulation begins as a liquid and once released into the atmosphere becomes solid and can expand up to 100 times its volume creating a complete barrier. The higher the R-value of insulation, which is a measure of resistance, the more resistant the insulation is to heat flow. The idea is to keep warm air in and cold air out in the winter and to keep cool air in and warm air out in the summer months.
Spray insulation tips
If you are insulating an attic, you will need to use open-cell spray insulation so that it can breathe; as attics generally require proper ventilation because of extreme temperatures. The walls of a home should be insulated with closed-cell insulation.
Protective clothing and goggles are imperative when tackling a spray insulation project. Plan this project in phases and insulate one area of your home at a time
