Simply put, home Insulation works by being designed to prevent cold air from getting into your house and keeping the warm air in, or vice versa depending on the season. TThe most common insulation materials work by slowing conductive heat flow, which is the term used to describe when heat moves through materials. In the winter time, heated air tends to spread out to colder areas such as garages and attics until the air temperature is neutralized. The insulation is designed to slow the heat from passing through the walls in your home.
Insulation can actually last up to 80 or even one hundred years, however, the insulation many homeowners have is often older than they think, so it is good to check if you are in need of an upgrade.
In general, closed polyurethane cell foam is considered to be the most effective insulation available. This is because it does the best job of maintaining stable indoor temperatures and is also resistant to environmental factors such as mold.
Insulation should not get wet. Over time leaks and mildew can greatly weaken the insulation and make it far less effective. This is generally because it causes holes or “weak spots” in the insulation that prevent the insulation from keeping in warm/cool air.
This depends on the type of insulation. Fiberglass insulation, one of the most common, is very resistant to fire. However cellulose insulation, which is made from recycled materials such as cardboard and newspaper, is very flammable.
Proper insulation can be very cost effective and will help save money on your energy bills, so it can save a lot of money in that way. Some states also give tax breaks for installing certain types of insulation. Visit the Energy Star Website to learn more.
