Mineral wool / Discussions

...wool (batten) right against the wood beams on the outside. Then an air barrier- WRB (as sealed as possible), then another layer of continuous rockwool board, followed by an air gap with diagonal furrings. Then we will attach vertical wood siding. Is this a good plan? Is the location for the air barrier right? To clarif...

...mineral wool between the studs, then cover it with drywall. I'm going to add mechanical ventilation & a dehumidifier to the basement. I have a few questions: 1. What kind of insulation should I add behind the rim joists? I feel like spray foam is the answer, but I'm a little concerned about off-gassing. 2. I'm worr...

...mineral wool insulation or rigid EPS foam. Mineral wool lets the moisture move right through it, EPS foam would be a perfect 2/3rds vapor barrier. That would be assuming you install at least 4 inches (about R24) if you have an 8 inch wall. This particular option for attaching rigid EPS foam panels to the exterior of a ...

...wool? Since we read about rockwool sometimes being too loose and falling out before adding the gypsum. Any advice for the best (and most ecological) sound proofing option for a first floor ceiling (not an attic) would be very welcome. Finally, how does the costs of a system using rock wool versus cellulose compare?    ...

...mineral wool and mold resistant drywall and paint with latex paint. Floor would be dimpled mat over concrete slab and vinyl plank flooring. No current plan to seal walls and we are leaving plenty of air gaps near unfinished ceiling where floor joists are. We would have a dehumidifier. Anything in here that jumps out as...

...wool mineral wool batt insulation between the stud bays but you are worried about the air space, why not just stick with the foam and skip the Rockwool? Given that you will already have a spray foam installer there, if it were me and I was already doing I would just have them do a couple more inches and skip the Rockwo...

...wool comfortboard mineral wool insulation at foundation skirting. We did just that on our 2015 demo house project, and the company wasn’t  a whole lot more helpful at the time for us either. Slab on grade foundation insulation is not a market they seem interested in competing in. They told us it *should* be fine, and t...

Hello I have a semi detached house in Toronto Canada. The house built in the 1930's is double brick wall. The house is original and has little to no insulation right now. I want to insulate the house from the outside with as high R value as possible. After insulation I was thinking James Hardie siding. Apparently brick...

...mineral wool insulation because moisture moves through it easily, or I would go thicker with something like the Thermal Wall foam insulation panels. Take a look at those pages and come back with any questions you have.

...Wool Comfort 80 Board to the entire wall, and then when the time is right frame and finish. If I’m getting this right, you had insulation in the rim joist cavities then a foil faced foam board over top? If so, the foil is acting as a vapor barrier and preventing moisture from escaping. The beauty of Rockwool Mineral wo...

Old house; basement is only 21% of total under house footage. 79% is crawl space. Basement Never painted. Walls go up 4 ft to a 2ft wide ledge and then the old stone foundation. 1 side is an exterior wall; 3 sides are crawl space beyond the stone.  A lot of heat is lost through uninsulated basement floors, so good idea...

...wool (or mineral wool) panels are a safe bet for you as they do not stop the outward migration of moisture. There are two brands that may be available in Saskatchewan, Rockwool (formerly Roxul) and Johns Manville. The other think you'll need is a weather barrier / weather resistive barrier (WRB), and a breatheable one ...

...wool comes in batt insulation as well as rigid, so  I wouldn’t be cutting it up to fit anywhere, they should have the sizes you need. Rockwool, (formerly known as Roxul),  is very permeable to moisture so while it isn’t the cheapest, it is the most foolproof as it won’t ever trap moisture like some foam insulation can....

...wool comfort board then 2 x 4 studs with rockwool bats.  I've also seen the part about possible breaking floor for a complete reno.  I'm just wondering if the poly is against the concrete or between the 2" layer of EPS and stud wall,  as well as if poly extends to bottom of first floor or stop at top of concrete?  Plus...

...mineral wool insulation with studs on 16oc all the way until Joist levels. ( Not insulated) can touch concrete. And no Vapor barrier. The basement is also dry and not humid. The joists are fully embedded inside the concrete slab. Hence, the floor above close to the baseboard is very cold.  My plan is to fully demo the ...
