- I strongly suspect that during the winter, we're losing a lot of warm air
- through the louvres of the whole-house fan. Even if I sealed the top of
- the fan with plastic, there still wouldn't be any insulation.
-
- My idea is to construct a plywood box around the fan, with permanent sides
- about 12-15" high. In the winter, I'd add a lid on top of this, with
- appropriate insulation and weather stripping.
-
- So -- first, will this actually do any good? Second, will the plywood box
- impair the efficiency of the fan during the summer? The peak of the roof
- is ~6.5' above the fan at the high point, alone one edge of the fan;
- naturally, it slopes down from there.
