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.
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 vertically around the entire perimeter of the room with width equal to that of the floor build up. 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).
Installation Instructions for DuraCork U34
Unpack the DuraCork U34 at least 24h before the installation and store it in the room where the installation will take place. Cut and trim the DuraCork U34 to the desired length and install directly over the subfloor with crown of the rolled materials up (removing eventual trapped air) Butt the DuraCork U34 directly against the insulation perimeter barrier already installed. Proceed to cover the entire floor making sure that the joints are butted tight.
After completion the DuraCork U34 should cover the entire flooring area without gaps and with joints securely taped. An insulation vapour barrier (p.e. foil) covering the entire flooring area MUST be installed prior to the screed. Install it, minimum 150mm wide vertically and overlapping it, minimum 100mm (use an adequate tape to fix it). After completion, the insulation vapour barrier should cover the entire DuraCork U34 area without any gaps. Never mechanically fasten the DuraCork U34 and/or the p.e. foil barrier with screws, nails or staples as this will severely diminish the performance of the insulation barrier.
Screed and Final Flooring
Cast a suitable screed over the loose laid PE foil previously installed over the product. Always follow manufacturers recommended installation instructions.
