Vapour Barrier and Sealant

Installed on the warm side of your insulation, a polyethylene vapour barrier is required by code for all insulations in our area.

Proper vapour barrier installation is important for reducing air flow and preventing moisture and mildew buildup inside your walls. The vapour barrier is installed directly over the insulation with no air space in between.  Keeping out any wrinkles, the vapour barrier can have a mirror like finish, completely wrapping your wall, ceilings and perimeter joists.

In order to be effective, the vapour barrier must be completely sealed.  All edges, joins, seams and penetrations of the barrier are finished with an acoustical sealant to further restrict the passage of vapour through the wall.

Please see our gallery for more information on properly installed vapour barrier and sealant.
