Hot Yoga Studio - Heat and Humidity in the Mountains

I'm doing an interior finish for a hot yoga studio in Edwards, Colorado, 7200 ft in elevation. The1000 sf studio will be heated to 105 degrees and 60% humidity 3 times a day. lasses are at 9:30 am and between 4:00-7:30 pm. The studio will be on the second floor of an older wood framed building. There are tenants on either side and a vaulted ceiling/roof above. The north and south walls are 24' wide with 2x4 framing with plywd. sheathing (building paper?) and t-111 siding with a couple of windows and a door on each side. The shared east and west walls are 40' with drywall and insulation.

Incrementally Increasing Insulation in PNW Walls

I am trying to develop a method of increasing the insulation in walls built in the PNW which does not interfere with the normative sequence or techniques of building used in the area. So to be clear this is a "pretty good" approach which doesn't require special trades or materials and can be used in typical houses without significantly increasing the cost, not boutique projects.

New fastener for applying exterior mineral wool.

We have been working with Fastenmaster in an effort to create a US made screw for applying Mineral Wool that sets in one motion and does not compress the MW. Therefore eliminating the need for "squash blocks" and making application quick while leaving the battens in plane. We have had some success and have a model built for 3" MW. A small production run has been made in the few thousand pcs range.

Insulate Ducts or Not?

I read the article on bringing the AC ducts within the conditioned space and found it interesting. One question I have that is not addressed, if the equipment and ductwork is now within the conditioned space, do the ducts need to be insulated? Is there code that addresses this?

thanks

DIY tightening up: corner cavities, foundation exposures

A few months ago I had my home insulated with closed cell foam. Now it's time to test it.

A good friend did a blower door test and took thermal photographs. It's a pretty good insulation job. There are places where the foam failed, but not many.

1) the framers created corner cavities "to hang drywall" (haven't they heard of clips?) that the insulators couldn't get to. I want to drill a hole a the top of the void and pump something in there to seal it up. What products can I use?

Has anyone used Superior Walls to create a conditioned crawl space?

I am preparing to build a new 2600 sf home in Fayetteville, NC. I like Superior Wall system and was wondering if anyone has used them for a conditioned crawl space. If so, how do you tie in the vapor barrier from the floor to the wall? How did price compare to traditional crawl space construction? Any info is much appreciated.

Re-siding and need to re-insulate but need advice

Hello,

I live in a 47 year old ranch house in Southern Maine (climate zone 6).

I plan to re-side the house in the spring and would like to improve the insulation while I have the siding off. I would especially like to improve the front of the house and air seal it well as the front faces North.
