Sub-Floor Boards

Water Resistant
No need to replace them in case of water damage - just let them dry.
Fire Resistant
This material is non-flammable.
Impact Resistant
Requires fewer repairs and touch-ups.
Mold Resistant
Mold and mildew cannot develop due to their anti-microbial composition.
Termite Resistant
Termites and rodents do not feed off this inert material.
Their dimensional properties remain stable under a wide range of temperature and humidity variances.
Their homogenous composition does not allow for delamination, increasing their durability and resistance.
Soundproofing Properties
Due to their high density, the boards contribute to decreasing and attenuating sound transfer.
Structural Properties
No need for blocking - cabinets and other elements can be fixed directly to the wall and they can be used in structural assemblies.


Overview:  KLEAN BOARD for Sub-Floors are available in two thicknesses: 15mm, 18mm or 20mm

These boards were developed to offer speed of execution during construction.  They can replace a light concrete screed and eliminate wait time for the concrete to dry.  They can be walked on immediately, saving a lot of time in the construction schedule. They are fire - mold - mildew - rodent - insect resistant. They do not delaminate. The edges are straight and even. They are available in several different edge finishes. The boards are tested according to ULC S101-07, with a 60 minutes (1-hour) fire resistance.
