[QUOTE="Carsyn.22, post: 2001620, member: 104613"] You are absolutely right, two totally different climates, here we need the closed cell for condensation reasons in winter, kinda like a walk in freezer in the sun on a hot Texas day... for 4 months steady no chance to dry out, it's just best that nothing get through. Warm air carries more moisture than cold causing a dew point in our walls, with closed cell the dew is trapped at a fixed moisture content at the time of installation. For Texas I guess open cell is probably not an issue... I never really thought about it. The point of insulation for you would mostly be to help your a/c correct? Not nearly the same extremes in temp for that application... [/QUOTE]
