The Best Basement Insulation Materials

Even though fibreglass insulation are often used in homes, mostly due to their low cost, rigid foam insulation systems are actually much better, albeit costlier, alternatives. Since they don’t compress and aren’t as susceptible to the elements as fibreglass, their R-value sticks.

Face it though, basements are often overlooked spaces in the home. Cause no one wants to spend much of their time in a cold and damp place, usually crawling with some form of microorganism that just loves the lack of insulation. But the sad truth is, your neglected basement is a big contributor to your home’s total energy efficiency. And as such, even with minimal use of your basement, it’s still a good idea to get it to be as economically efficient as possible.

The two most popular ways of insulating your basement are either by air sealing or by upgrading your current insulation system.

By air sealing, you’ll be securing round the foundation from air loss. The foundation perimeter is where cold air usually enters and escapes in your home. Hence why your relatively small home takes a long time to heat up. Of course the basement is not the only point of air entry. External doors are also a great point of entry for cold air, so they’ll need air sealing as well. Basically, air sealing with rigid foams, despite their initial expense, could save you money, from heating bills, in the long hurl.

Various Places Where Basement Insulation Can Be Installed

Unfortunately, for quite some time, builders had been installing fibreglass batts in the area between the floor (ceiling beams) and the basements. They didn’t realise that this meant the basement was cut off from the entire building’s physical structure, which is meant to have free flowing air. So the building envelope, which serves as some sought of border between the inside and the outside of the home, ended up being separated from the basement.

Thankfully more advance in building technology, means all hope’s not lost. Just liberally apply your adhesives to the wall and stick the rigid foam boards on them. Place something, like timber, on the affixed boards until the adhesive cures. If you notice any gaping space between boards, you can put some tape there.

Basement Wall Insulation – A clever Move

As long as the walls of your basement are properly insulated, they’ll be a part of the building envelope. Hence when you want to heat up your home, it’ll take a much shorter time, ergo save more energy bills since you are conserving more heat.

Moreover, several other functions like your hot water lines and the ductwork from HVAC will be protected when your basement is well insulated. They’ll function even better than they did during your last winter, where you probably had to ration hot water, since exposure to the elements would have meant poor performance of heating and hot water machineries. Typically at several dollars more than usual.

It’s possible to install rigid foam, both from the interior or exterior of your building. Though you’ll find that most people install theirs from within.
