Attic climbing gym for etk
« on: July 06, 2020, 12:04:55 PM »
Started on project attic renovation into rock climbing gym.  First task at hand is demo and re-insulating as its not done properly now.  It is a "knee-wall" configuration with ridge vents only.  Currently the rafters are insulated up to the ceiling and blown in on top.  No soffit vents or baffles for air pass-through.  I plan to add soffit vents, baffles and insulate the knee wall and floor to have have a "cold-space" to hopefully fix my ice sickle problem.     

Problem #1 is the rafters are 2x6 and the baffles take up about 2".  This leaves me only able to use 4" insulation which is not ideal, but acceptable.  But, 4" insulation is not available in 24" wide anywhere that I've looked. 

I would rip some extension pieces to bump it out to 2x8, but I really don't want to add an extensions as I'll be screwing the climbing wall board to the rafters and there is just not enough meat to screw it all to the rafter securly. 

I hate working on houses...

Thinking it may be wise to just build an dedicated angled wall fastened floor to ceiling.  That's more work than I wanted to do.

You used regular 3.5" batt and baffles in a 4" cavity?

I found some 3.5"D x 24"W batt on HD website but it appears you can only buy in a pallet.

Let me see what I can see in my construction pictures to jog my memory.

I know I did the baffles down at the eve during redecking in prep for blown fiberglass, and I did several things to breathe from that roof to the peak which it hadn’t done before my work (which is why it all needed new decking)

I know i added 2” foamboard in that area as well but let me confirm I did the baffles and batting there too

I'm asking because my understanding is you should take the depth of the baffle out of the insulation thickness as your not suppose to smoosh it.

That’s correct. Smooshing will reduce r value.

Breathing is more important than insulating for longevity and it seems like you’re staying there a minute. So I’d fix the breathing, given the choice.

The baffles will smoosh some too, if pressed, which is its own challenge.

Added the only applicable pics from oct’16 to my second roofing thread just now. Fun reread.

Plan to cut some 16” in half and hold it all up with vapor barrier. Fuck that price.

Agreed on ventilation over insulation, there were a few spots of black mold on the underside of the roof.  Sealed it with mold primer.

Oh man Idk.  I might bite the $200 bullet on this one, I'm very sensitive to fiberglass.

I’d spend half a day for beer if you want. Especially in the next week and a half when I’m still laid off. I’m pretty tolerant of irritants.

Although... I need to get this rodent situation handled. Someone had one in her office this morning and is more than a little rattled. All was fine when the cat was catching them in the basement. Now not so much fine even a little bit.

They’re going places they haven’t been since their habitat is destroyed. I’m babysitting one under the dishwasher right now, quite sure it’s the one that was up in her office this morning. She saw it make the living room, I saw it make the fridge and it went under the dishwasher when I moved the fridge.

72 cheap Sticky traps and a dozen snap traps arrive Thursday.
