If you live in an area with extremes in temperature, you need to be concerned with your home's overall insulation. High-quality insulation can keep out excessive heat and humidity, as well as bitter cold, so you spend less money on your utilities and protect your home's building materials.

Improving your home's insulation doesn't necessarily mean replacing the fibreglass that is behind the home's walls, as there are other ways of upgrading a home's insulating properties. Note what this means, and a few tips on improving your home's overall insulation, no matter the climate where you live.

Roof

Much of the home's heating and air conditioning is lost through the roof, while cold and especially heat from summertime sun also enter through the roof. You don't necessarily need to have a roof replaced to improve its insulating properties; consider a roof restoration, which involves a spray-on foam or other such substance that seeps into cracks and exposed areas of the roof, covering them over and thereby improving the home's insulation. This spray-on material also adds an extra layer of insulation over roofing tiles and shingles, increasing their insulating properties as well.

Security doors

You may think that security doors are designed just to keep your home safe, and certainly, this is their most prominent advantage. However, note that security doors are usually very thick and made of solid materials that are meant to be difficult to break. These doors also typically sit snugly in their frame, so they're harder to open with a pry bar. These factors make security doors better at insulating the home's interior than many standard entryway doors! Upgrading to security doors can mean fewer drafts and less heating and cooling that is lost through the doorway itself.

Windows

Your home can lose lots of heating and cooling through the windows, so add new caulk around window frames as often as needed, to block drafts. You might also upgrade to better-quality windows themselves; double-glazed or triple-glazed windows block heat and cold, and keep in your heating and cooling, for a more comfortable environment in the home.

This can be an important upgrade to consider if you have areas of the home with wide, large windows that span an entire wall, or that get hit with lots of direct sunlight during summertime. You don't need to add window film or cover the windows with unsightly drapes if you upgrade to double glazed windows with specialty glass that reflects heat, as this will make the interior of the home more comfortable overall.
