The Invisible Failure In Windows
You never think about window seals when you're looking at house plans or looking through building quotes.
That's because they are part of the frame, out of sight.
When poor-performing seals shrink, crack, or fail to compress properly, your home becomes cold and drafty.
At Koffman, we use European multi-point continuous compression seals that pull the window sash tight against the frame along every millimetre of the perimeter when locked.
Cold air infiltration is completely shut out, locking drafts out and preventing heat from escaping around the edges of your windows.
