Plywood Underlayment: Halex Plywood Underlayment: Product Guide

Plywood Underlayment Thickness

6mm Plywood Underlayment Halex 6mm plywood underlayment meets the APA standard for 1/4 inch plywood the minimum recommended thickness, as well as the standards of all major vinyl brands. Halex 6mm plywood underlayment is composed of 5 plies, which make it an even sturdier alternative to standard 3 ply plywood underlayment. It also provides additional strength over all 5.2 mm and 5.5 mm plywood underlament porducts. Use for sheet vinyl, vinyl tile, rubber tile, and carpet installations over suspended wood-based subfloors. Not recommended for ceramic tile installations; use a 9mm plywood underlayment in these situations. 6mm plywood underlayment is available in 4x4, 4x5, and 4x8 sizes.
9mm Plywood Underlayment Halex 9mm plywood underlayment meets the APA standard for 3/8 inch plywood and meets the performance requirements of the Tile Council of America for installation under ceramic tile. It is 50% thicker than 1/4" plywood underlayment, and is composed of 7 plies, forming a construction strong enough to provide a safe and solid foundation for ceramic tile over L/360 subflooring. 9mm plywood underlayment may be used under hardwood and laminate flooring, and under resilient floors when installing over existing cushion vinyl, to improve the stiffness of the subfloor or to compensate for the removal of a thick previous floor. 9mm plywood underlayment is available in 4x4, 4x5 and 4x8 sizes.
