Have you noticed your energy bills going up this winter? If one or more windows in your home are the worse for wear, this can happen. According to one source, doors and windows can eliminate as much as 25% of your home’s heat loss. Airtight windows and doors are essential to energy efficiency in homes and buildings. You can avoid air leakage when you purchase and install airtight windows and doors in your Toronto house. You’ll be able to eliminate drafts, reduce energy bills, and increase interior comfort.


Window Airtightness: What Is it?

Do you know what airtightness means or how to make windows airtight? Airtightness refers to a building’s resistance to air leakage — meaning air flowing both into and outside of the building in question. Window airtightness is essential to window energy efficiency since it safeguards against drafts and maintains a consistent interior temperature.

Quality windows from a reputable manufacturer can last 15 to 20 years. But if your windows are nearing the end of their lifecycle or are otherwise no longer efficient, heated or cooled air can escape. You’ll see higher utility bills and experience less interior comfort if you don’t have airtight doors and windows. Other essential benefits come with getting airtight windows. For example, you’ll improve indoor air quality since airtight windows will keep outdoor pollutants from seeping into the building.

Types of Airtight Windows and Doors

Are you looking for an energy efficient airtight window or door for your Toronto home? Various kinds of airtight windows and doors can improve the energy efficiency of a home or building. Some of the most common types include the following:

Double-paned windows

Double-paned windows have two panes of glass with a sealed space in between them. These types of windows will insulate your home and lessen total heat loss. You can bet that window change will improve house airtight.

Triple-paned windows

These windows consist of three panes of glass with a sealed space between each pane, which provides a greater amount of insulation.

Low-E windows

When you buy these types of windows, they’ll come with a special coating on the glass that reflects heat back into the home. What this will do is lessen heat loss in the winter and reduce the flow of hot outside air into the interior of your residence in the summer.

Gas-filled windows

Another way to get energy efficient windows is to select options with gas between the panes of glass. Gas options include krypton and argon, and they’ll boost the insulation properties of the windows.

Casement windows

Casement windows have a tight seal around the window when closed. So, they provide an airtight fit.

Airtight doors

Airtight doors are constructed to prevent air leakage around the edges of the door. These days can be made of fiberglass, solid wood, or steel and contain weatherstripping or some other sealant components to prevent drafts.

Sliding glass doors

Sliding glass doors have a tight seal around the door when shut and also have weatherstripping or some other sealant option to stop drafts.

Bi-folding doors

You’ll often see these types of doors in modern architecture. They’re constructed with an airtight seal when shut and also have weatherstripping or other sealant elements to safeguard against drafts.

These windows and doors are constructed to boost the energy efficiency of a home or building by preventing drafts and cutting down on heat loss.
