...EPS rigid foam insulation. EPS is typically rated at abou R4 per inch where GPS is typically rated as having R5 insulating value. Here is our page about choosing the best rigid foam insulation where we talk about the charateristics and best applications of different foam products. 

...EPS rigid insulation, I wouldn’t worry too much either way about air gap or no air gap, because concrete walls aren’t perfectly uniform, so unless you spread a thick coat of adhesive evenly over the whole surface of the EPS and press it firmly to the wall until it sets, there will be minor air gaps. Whether you try or ...

...EPS and then vertically strap for Rain screen and put vinyl or wood siding on top. My question is whether I should be removing the old plywood and asphalt sheathing and possibly the old insulation. and reinsulate and sheath. As well should I be putting the WRB barrier on the sheathing or the outer rigid insulation? Las...

Eight years after our house was built, we noticed that the MDF baseboards in our finished basement became discoloured and swollen from potential moisture. We removed the dry wall, the vapour barrier and the fibreglass insulation in two large areas along the same back wall. The concrete appeared to be saturated with wat...

Thanks, Chris We have fully detailed plans for how to insulate basements properly to avoid mold, heat loss and water infiltration, see this page here - Best practices for basement construction - new home or renovations  Thar should provide all the answers you need, and feel free ...

...eps to reduce the humidity? What should we put on the uninsulated floor as a covering that won't go moldy/smelly like the carpet has (and we're on a budget, and have next to no headroom.) I appreciate there's no perfect solution - but I wondered whether we would be better getting a continuous drain dehumidifier, a HRV ...

I am about to start a full strip out and rebuild of my basement to make a secondary suite. I've been reading all the information on the site and find it very useful (and educational). I am a carpenter from Scotland living in British Columbia now and as we tend not to have basements at home, I'm finding it a learning cu...

I read in one of your articles when putting up rigid foam to Install two inches of rigid insulation board directly against concrete.  A mold expert told me to put the board on top of the framing, not directly onto the concrete wall so the house can breath.  What is the right course of action? Thank you Can you please e...

...EPS & XPS Foam Insulation & Styrofoam We always choose (and recommend) EPS over XPS due to the fact that XPS has much higher greenhouse gas emissions than EPS.  So if you are looking for suggestions we would say go for the EPS, and if you want added protection, source one with a foil backing.

...eps might be the best to use,  but not sure if the foil face would be good, may not be breathable...might be better to just do eps board and buy attic foil to put over that .....this might be the cheapest way to get some insulation on the out side of the building for the thermal break .....rock wool would be good if I ...

...eps needed to do this correctly . Once again, thank you very much for taking the time to read this and also hopefully provide some insight.    To find the best exterior insulation to use when renovating old homes, we often recommend Mineral wool (often referred to as Roxul or Rockwool). We like it for the very reasons ...

...EPS. Is that a danger? Among the many possible ways to protect against that doesn't involve insecticides that might leach into the soil is a copper foil sheath around the outside of the foundation. Are insect infestations in the EPS a possible danger? Thanks, James.  

...EPS. Tyvek, siding. I intend to remove the EPS and install a self-adhering WRB on the plywood. Since I have the EPS will I create any problems if I re-install it and add 1 1/2" Rockwool Comfortboard 80 over the EPS? When insulating the exterior of a house whether that’s a new home or adding insulation to an existing ex...
