The following installation instructions are recommended by Durabella Acoustics Limited, but are not intended as a definitive project specification. They are presented in an attempt to be used with recommended installation procedures of the flooring manufacturers.

Room Conditions
Temperature >10˚C / Room moisture content < 75%

All subfloor work should be structurally sound, clear and level. The moisture content of the subfloor should not be more than 2.5% (CM) by weight measured on concrete subfloors.

Perimeter Insulation Barrier
Install a perimeter insulation barrier minimum 35mm wide vertically around the entire perimeter of the room. This is highly recommended in order to avoid lateral propagation of impact noise. Spot adhere the strips to the wall using acrylic glue or a bead of silicone sealant (do not forget the edges of pipes, ducts, etc). Before the installation of the skirting boards, the insulation strips must be leveled (trimmed) to the height of the wood.

Installation Instructions for DuraCork T31
Unpact the DuraCork T31 at least 24h before the installation and store it in the room where the installation will take place. Cut the DuraCork T31 to the desired length and install directly over the subfloor. Butt the DuraCork T31 directly against the insulation perimeter barrier already installed. Apply suitable polyurethane glue in all perforated areas of the DuraCork T31 in the amount recommended by the manufacturers.

Final Flooring
Use polyurethane based adhesive. Always follow manufacturers recommended installation instructions.
