Our take on the K Flex USA 6RSX3X4038 Elastomeric Foam Sheet 36 in X 48 in X 3/8 in Thick

This is a closed-cell elastomeric foam insulation sheet from K-Flex, 36 by 48 inches and 3/8 inch thick, covering 12 square feet per sheet. It is the flat-sheet form of the same flexible foam used for pipe insulation, meant to be cut and wrapped around ducts, tanks, large fittings and flat surfaces. It suits HVAC and plumbing work where pre-formed tube insulation does not fit. Compared with fiberglass wrap, closed-cell foam resists moisture vapor and needs no separate jacket, but it is sold in large sheets and is harder to shape around tight bends.

Questions and answers

Is this sheet the same foam as K-Flex pipe insulation?
Yes. It is the same closed-cell elastomeric foam in flat sheet form, so it can be cut and wrapped where tube insulation will not fit.
What can I insulate with a 3/8 inch sheet?
Ducts, plenums, tanks, large fittings and flat or gently curved surfaces. For small-diameter pipes, pre-formed tube insulation is easier.
How much area does one sheet cover?
One 36 by 48 inch sheet covers 12 square feet at 3/8 inch thick. Plan seams and overlaps before cutting.
Does it need a separate vapor barrier?
No. The closed-cell foam itself acts as the vapor barrier, but seams and joints must be sealed with the proper adhesive to keep that performance.
How is it attached?
It is typically bonded with contact adhesive made for elastomeric foam and sealed at seams. Follow the adhesive maker's instructions for cure time.
