GENERAL INSTALLATION INSTRUCTIONS
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%

Subfloor
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 T42
Unpact the DuraCork T42 at least 24h before the installation and store it in the room where the installation will take place. A properly sized V-notched trowel and polyurethane flooring adhesive should be used to glue the DuraCork T42 to the concrete slab. Always follow the glue manufacturers recommended instructions.
Lay the DuraCork T42 sheets, with the rubber/cork side facing down into the bed of adhesive applied. Butt the sheets tightly against the perimeter insulation barrier already installed. Procede to cover the entire floor making sure the joints are butted tight, without gaps and securely taped. Roll with a roller the floor area in both directions to make sure the sheets are firmly embedded in the adhesive.

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