XPS foam / Guides

...foam panels was compared to the same assembly using 2" of EPS foam and was found to be losing 30% more heat in this study (see below)! XPS - Extruded Polystyrene Foam Panels - The blue, pink or green ones (eg. Styrofoam): XPS is Rated at R5 per inch, but it will off-gas and lose some insulation performance over tim...

...foam has an R-value of 6.3 per inch; when used at an 8-inch thickness, the foam has an R-7.4 value per inch, which exceeds the performance of any foam insulation currently on the market. The installation of spray foam requires the mixing of chemicals on site, and that reaction generates a lot of heat. So spray foam b...

...foam products on the market, when in reality it isn’t actually as bad as people think. They are easily distinguishable from each other, see below: EPS - Expanded Polystyrene rigid foam insulation, aka 'beadboard foam insulation'. this is NOT 'Styrofoam'. XPS Extruded Polystyrene rigid foam insulation - this...

...foam insulation needs to "come out of the shadows" of being lumped in with Styrofoam as it makes absolutely the best sense per $ and environmentally for continuous and resistant insulation in buildings. Extruded Polystyrene Foam (XPS) Extruded rigid foam boards most often Styrofoam Recycled content : Mi...

...Foam must be covered by drywall for fire protection. Don't install an additional vapour barrier behind drywall ; latex paint will act in this capacity.

...foam boards directly to the concrete using either strapping and tap con screws, or an appropriate adhesive that is suitable for foam boards (it should say so on the tube). EPS can be substituted with XPS foam, but given its much higher greenhouse gas emissions, we prefer to recommend EPS. XPS qualifies as a vapour barr...

...foam if you choose (spray foam is our least favorite but it can be done so we mention it, though we always encourage readers to choose spray foam with the safest blowing agents ) Larsen truss walls can be made in a variety of thicknesses, which is a really nice advantage to the design as it can be done in a way that ...

...foam insulation boards © Michel Chenier As an example, the above stack of XPS foam insulation was purchased through an online classified website for $3 a sheet, whereas purchased new in a building supply store they would retail for about $40 a sheet. It doesn’t take a calculator to know that that’s a pretty...

...foam industry. Beyond just couches, chairs, mattresses and pillows, we build our homes with it. EPS and XPS foam are two of the most common insulation materials in the residential housing industry, and they are full of fire retardants, even in applications where there is simply no way they will combust, such as when us...

...foam and XPS foam with lower emission blowing agents Styrofoam board insulation and spray foam insulation have always had a bad rap in the green home construction industry, and not without good reason , but the true problem is not what most people think. A brief pause here while I slip on the Kevlar vest I wear when ...
