| Re: Attic Home Theater
Hello All - plan to post some new pictures soon. To answer the questions about the insulation - I wanted to wait until we were done a little more to let you know how it worked out.
We have 2x8 joists, so R-30 was a problem with providing an air gap. We ended up using high-density foam sheets. You get R-15 for every 3", so we used standard duct chutes and then placed two sheet thicknesses between each rafter (cut to size with a table saw).
Overall it worked pretty well except the rafters weren't straight, so getting the foam to be a tight fit was a bit of a challenge. But this was our only real solution, as building down the rafters to 2x10's or 2x12's would cut into the headroom more than I liked. Overall, we have 10 feet at the center, going down to 2 1/2' high knee walls.
So overall, it worked, but it was more expensive and more time consuming than expected (like most home improvement projects :-) )
