Location: western PA | The insulation isn't sealed well enough to prevent the inside air from reaching the outside skin. When this happens, condensation is formed and with no place to exit, becomes a detriment. All exposed edges of any insulation should be finished with tape and the joints should be air tight. The inside edges of the beams should also have some insulation covering, to prevent the outside cold to reach the inside surfaces. On a cold day, you can actually feel the cooler structures on the interior surfaces. Strips of rolled foam insulation can be applied to the studs and structures before the interior panels are installed. The most important criteria, is to seal the joints with tape or spray foam, to stop any air movement through or around the insulation. |
