Cork is a renewable resource, harvested from trees without killing them. Although it comes from far away (mostly Portugal), its carbon footprint from transportation is quite reasonable given that it is light-weight and can be made very thin.
The Edelweiss House is a slab-on-grade concrete floor covered with 1/8 thick pre-finished cork tiles from Lusimat, installed with a Zero VOC GreenForce adhesive from Bostik. We thank them both for taking part in this project, helping us reach our target of LEED Platinum while creating a healthy and beautiful interior living space.
As I read this I am curious as to the heating load loss on your cement pads thermal mass by putting this product down
Hi Lee,
I think you are asking if the cork insulates it and reduces the heat transfer, right? It would in a minor way, but the insulation value of 3/16ths of an inch of cork is next to nothing compared to the 8 inches of insulation underneath (R32), so it really wasn't a concern for us.
