...insulation panels and how they could possibly pose a problem on the exterior of homes. Choosing between plywood and OSB sheathing – which is better? So the WRB sheathings we like, but we become a bit more concerned when panels have integrated insulation though. I did have a quick look at the Barricade Thermo-Brace prod...

...insulation products.  There are also some significant ecological downsides to spray foam insulation, information about that (and the advantages - the ones with the newer more eco-friendly blowing agents) can be found at this page here, so have a look as it will likely answer most of your questions -   New HFO spray foa...

...insulation. It has a slightly lower R value per inch, but it’s about half the price and has a fraction of the global warming potential, you can read more here on our page about choosing the best rigid insulation panels. 

...insulation, rockwool or EPS . If you are doing the exterior then you can follow the procedures for exterior insulation here in page about the best way to insulate basements.

...insulation was added on one of the walls (all others checked and fine) condensation is building up after I waited a month or so into winter and pulled the insulation out to check. This particular wall is not buried fully like the rest (due to slope of property) and it is exposed to the outside temps top to bottom from ...

We had a water leak in our basement earlier this year and when the contractors started pulling off damaged drywall we were disgusted to find that our basement wall framing was rotten in multiple areas and the insulation was full of mold behind the vapor barrier. The scariest part is that our house was only built in 200...

...insulation for better energy efficiency Granted, that cinder block foundation repair technique is for a slightly colder climate, but that just makes it a bit easier on you, and the science behind the moisture movement is the same. Is there any efflorescence (moisture stains) on the walls?
