Choosing the right house wrap / weather barrier, which is best?

...insulation on the exterior, that as well will have a vapour permeability rating that should be considered. As an example, 2 inches of Roxul ComfortBoard is rated between 30 and 40 perms, compared to 2 inches of EPS foam which is about 1 perm, and 2 inches of XPS foam is only about .5 perms. Meaning, by putting 2 inches...

...insulation against frost heave. 'Insulation' does this as well, so laying a rigid foam insulation board down (foam or stone wool) below and around the deck block may reduce the chances of movement from frost heave. Laying down a bed of 3/4" clean crushed stone will also act to prevent frost heave, it just can't have an...

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...
