insulation goats

anyone ever try rigid foam and batt on block walls on an above ground (2nd story) application? the walls will be finished with 12" shiplap pine boards in a vertical orientation.

so, vapor barrier? and should it be sealed with expanding foam? should I stud with 2x6s and leave an air gap between the 2 different insulations? fuccck.

never heard of that. the 2nd story walls are block?

i'd figure straight up spray foam would do the trick no?

not sure why you would use 3 kinds of insulation. rigid, batts, and spray

so using just the rigid or the batt wont really give me a high enough r value for the above the garage, recently converted living room. I could double up on 2" rigid but its super expensive, and the batt by itself isn't quite enough protection.

2nd story block walls are hot in summer and cold in winter. water/moisture isn't an issue, I just need to get the space to hold heat.

I could stud the walls on 24" centers and put precut 2 foot pieces of rigid in each cell and then use cans of expanding foam to seal the seems and cracks, then put batt on the studs and the pine boards of that


I can rigid the whole wall(s), seal with tape. then frame in front of the rigid (so the studs aren't touching the block) and then either put more rigid in the cells or going with like a cost effective batt.

I could put a vapor barrier on the walls to start or one over the studs and batt, just under the exterior wood or not use another since the rigid is closed cell and the batt has one built in.

most all videos and application I have seen for this are based on the block walls being underground or in a basement level where it is partially submerged, and water leech/moisture is the concern.

I have no moisture issues being on the second floor, but I do know that the porous block does retain some moisture and breathes, I don't want condensation issues.

also rubber dicks and stuff

so I guess opinions on wood pellet stoves wont go over very well either?

no natural gas in your area?
ARCHITECTkills 11/14/2017 1:27:20 PM
nope gas lines in my area, I do have LP for furnace and stove but prices are kinda gay. plus if the power goes out the furnace cant run anyways. WiseWay makes a gravity fed non electric pellet stove. reviews are mixed but it seems pretty sweet.

if not prolly go with a regular pellet stove to subsidize the arctic fck frost I live in and a Generac back up generator.

either way its like 3500.00 bucks minimum.

how do I convince my lady that THIS is the best xmas gift ever?
