Continuous Insulation How to Video

May 15, 2013

Our homeowner from Monday’s blog, Ted Hubert, applied DuroFoam insulation over his exterior above grade walls to create a continuous layer of insulation. You can retrofit your home or apply this method to new construction using some of our other product lines as well. Aside from DuroFoam, you can use PlastiSpan or PlastiSpan HD to complete this project.

This video takes you through the steps to insulating your home with exterior sheathing, also known as continuous insulation using PlastiSpan insulation by Plasti-Fab.

    WARNING ! This procedure may cause an Exterior Vapor Barrier, trapping moisture in your insulation and wall cavities.

      In compliance with the National Building Code of Canada 2010 (NBC 2010), Plasti-Fab Product Information Bulletin 287 addresses the use of PlastiSpan and PlastiSpan HD insulation board as an exterior insulating sheathing board applied to above grade walls.

      The Vapour Barrier System Requirements of this code requires all thermally insulated wall, ceiling and floor assemblies to be constructed with a vapour barrier sufficient to prevent condensation.

      Wall assemblies with ratio of outboard to inboard thermal resistance values greater than those given in Table of PIB 287 ensure that the inner surface of the insulating sheathing is likely to be warm enough for most of the heating season such that no significant accumulation of moisture will occur. As well, the vapour barrier function has to be provided by a separate building element installed on the warm side of the assembly.

      Plasti-Fab PIB 287 can be found in the Technical Information section of the web site, or you can download it here:

    Having read this I believed it was really enlightening.
    I appreciate you taking the time and energy to put this article together.
    I once again find myself spending a lot of time both reading
    and commenting. But so what, it was still worthwhile!
