Hi Lynelle,
<div class="">I know Wasaga Beach well.</div>
<div class="">The DryCore product idea is a good one, BUT it does not add much insulation. Your standards are a bit higher I think than R-2.</div>
<div class="">Hence, the approach shown in the cool example retrofit Norbert provided a link is is more appropriate, IF you have an additional 1 or 2” or headroom</div>
<div class="">That approach would be low vapor permeance foam (such as EPS, R4/inch XPS R5/inch or even polyiso R6/inch) all available at local supply stores in Ontario. 1” of polyiso will be three times the insulating </div>
<div class="">Then a vapor AND airtight layer on top. This is often easiest achieved reliably by taping the joints in the foam.</div>
<div class="">Then you can put a floating floor of T&G OSB direct on top (some use glue in the grooves to joint the system together) leaving 1/2” or so around the perimeter and penetrations to accommodate movement. Then flooring.</div>
<div class="">Or especially if on a budget and limited height, add rolled dimple sheet (like System Platon or Delta Dry), tape the joints, and direct apply click flooring over the thin underlay.</div>

Hello Listers<br class="">
<br class="">
I hope some of you are still here!<br class="">
<br class="">
I've bought a home in Wasaga Beach, Ontario. It's an Upper Canada Post and Beam with Board & Batten siding. I know I will have to upgrade insulation, but have a question about the basement. It's a walkout and will be regularly used for living space. It is
currently carpeted, but that will be recycled when I take possession. I want to insulate the concrete slab and have looked at the insultaing versions of DryCore and Amvic, under a hard surface (bamboo )<br class="">
<br class="">
I've never insulated an existing slab (always insulated under them when building). Anyone use either of these products or something better? Lower area is about 900sq feet. Walkout is open to the NW.<br class="">
<br class="">
Hope everyone is well.<br class="">
<br class="">
Thanks in advance,<br class="">
<br class="">
Lynelle<br class="">
