Finishing the exterior of an insulated slab-on-grade floor

...board , though that left the challenge of how to attach it without using metal fasteners that would lead to thermal bridging. What we decided on was plastic straps that passed through the cement board and that were anchored in the concrete. It did hold as planned, though there is more play in it than we ideally would...

Rigid insulation panels: which ones to use for different applications

...insulation boards very carefuly to reduce their environmental impact. All XPS panels are not equal! EPS - Expanded Polystyrene Foam Insulation Boards: Rated at R4 per inch; EPS foam insulation boards are more permeable to air and moisture than XPS, but it doesn't retain moisture to the same extent because of it's m...

...board), MDF (medium density fibreboard, particle board and plywood will contain formaldehyde and VOCs. Hemp Coreboard on the other hand, is non-toxic and does not contain formaldehyde and toxic resins. Coreboard is also manufactured using a sugar-based binder, therefore hemp building products can help contribute to cle...

Choosing the right insulation: the pros, cons and applications for walls, slabs & basements

...insulation panel that one day we hope will replace plastics based foam as a standard building insulation. And better still is when the natural alternative for these plastic based rigid foam insulation boards is a naturally derived cellulose high-performance panel with a higher R-value than current rigid insulation pane...

Insulating below slab-on-grade floors

...insulation can be very quick if not instantaneous, as added material costs are offset by money saved monthly on heating. The insulation we used here is Rockwool rigid board under the main slab and on the exterior of the slab, and high-density Type III EPS foam under the footing as Rockwool has not been tested yet for...

The Difference between air barriers and vapor barriers

...insulation on the outside of the vapour barrier. Air barriers on the other hand can come in the form of house wrap (WRBs) , tightly sealed sheathing, insulation that slows airflow, and well-sealed gypsum board (drywall). To explain this further, Gypsum board (drywall) is vapor permeable, but stops air flow. This mean...

...insulation is installed outside of that. Stud cavities are still insulated with batts, but the majority of insulation is on the outside of the sheathing, this way the vapour control layer is sandwiched between layers of insulation where it can perform best in a wildly varying climate like we have in Canada. There a...

Dense-packed cellulose insulation wall systems

...insulation can be a superior product to commonly used batt insulation, but somehow it has developed a bad reputation in Canada. Cellulose Fibre Insulation (CFI) is like the Rodney Dangerfield of insulations, it "can't get no respect". When done right, dense-packed cellulose is a highly efficient option for insulating...

How much insulation is too much in attics and walls?

...insulation is too much in an attic? What does ‘diminishing returns’ for insulation mean? It's as simple as this - adding one inch of insulation to a wall that has only one inch of insulation is certainly well worth the investment, in any climate. Adding one inch of insulation to a wall that has 5 inches of insula...
