We want you sitting in your warm Natural Spaces dome chuckling about your neighbor in his cold, conventional, expensive house. Condensation Condensation can be described as the change in moisture from a vapor to a liquid. During warm or sunny periods, the frost melts. When conditions are severe, this meltdown in unvented spaces may drip to the ceiling below and damage the interior finish. Wood sheathing may swell up.
Insulation becomes wet and looses it's resistance to heat loss.
These problems can be reduced or eliminated when proper construction details are used. The control of condensation thru the use of vapor barriers and ventilation should be practiced regardless of the amount of insulation used. The use of both inlet and outlet vents in attic and roof spaces aids in keeping the air moving and preventing the accumulation of frost or condensation roof sheathing in cold areas.
