Ok, I've broke ground on the HT construction. So far I've just put down the plates for 2 new walls that I will need to frame out in front of the current block walls. I also put Tuff-R insulation board on the face of the block walls, to give a little vapor barier and warmth.
Here are some basic ideas I have for the construction:
-- 3" mineral wool in the 2 x 4 framed walls I'm constructing
-- 3" mineral wool with fiberglass insulation behind it in the existing 2 x 6 walls
-- Superseal under carpet and padding (
www.superseal.ca, $88 for 166 ft^2 roll plus ~ $11 per roll for 2-day ground FedEx)
-- Sheetrock walls with DIY panels at first reflection points
-- two rows of couches (the kind with a reclining seat on each end)
-- drop ceiling (I really wanted to avoid this, but because of the need for future access, I don't think I can)
I will also be building a stage and soffit similar to the Tanner Ridge build, and my equipment will be housed in the right rear corner in a cabinet I will build. I hope to pack all voids full of mineral wool insulation.
I found a local source for mineral wool insulation that seems to be a good price: 3" x 24" -- 68 ft^2 of coverage for $16.64 a pack
I don't have an actual part # but it's made by Roxul. I will try to get more info and post it so that I can get some feedback on whether I'm buying crap or not.
Thanks again for all the advice so far--any further comments? Maybe pics will follow over the weekend . . .
