Installation

1. SUB-FLOOR
Make sure the subfloor is structurally sound, flat and dry.

2. DURACOUSTIC®
Install black side down, fibreglass up. Adjoining edges should be butted and taped together.

3. PERIMETER
Install polyethelene foam or fibreglass board at the perimeter of the entire subfloor and around any protrusions through the installation. The isolation of the floating floor prevents flanking between floor and walls. Tape or tack-glue the isolation material.

4. GYPSUM CONCRETE
When a Gypsum concrete overlay is poured, please refer to supplier’s instructions.

5. CEMENT BOARD
Cement board (1/2”) should be installed with a 1/4” gap between units, taped on both sides of joints (2” coated fibreglass tape) and butt bonded with latex portland cement bond coat.

6. PLYWOOD
The two layers of plywood must be 90° to one another, joints gapped and offset, top sheet glued
(full coverage, non water based) to bottom sheet.

The two layers fastened with screws in corners
and center with no penetration into DURACOUSTIC® (prevents flanking). The plywood should be 1/2” for hardwood floors and 3/8” for ceramic, vinyl, carpet and pad.
