We live in the North East. We moved into our newly constructed home in September. We built a timber frame with stress skin panels. The windows are sweating terribling even with a dehumidifer running since October. The windows are double hung Pella clad melt exterior with wood interior. When the temperature outside is in the 30's we have very little moisture when it goes lower than that the moisture builds and we had ice on the inside. We built a home in 1986 and had moisture the first year but not this bad we fear the windows will be destroyed. Please help.
