A standard domestic floor/ceiling construction with square edges floorboards will only give around 36dB of airbourne noise reduction and around 82dB of impact noise reduction. This can be improved on greatly if the following measures below are implemented. The fire performance, by adding additional plasterboard to the ceiling below, is also increased to 1 hour.

Installation as a Basic Floating Floor.
Before laying the insulation it is important to ensure that the floor itself is perfectly sealed. Any small holes or gaps should be filled with flexible mastic or overlay the whole floor with soundproofing mats, glued down, to reduce airborne sound penetration.

The insulation is simply unrolled over the existing floor. All edges should be butt jointed and offcuts can be re-used. The R10 can be cut easily with scissors or a sharp knife. 18-22mm T & G Flooring Grade Chipboard should be applied directly on top of the insulation. The T&G floor surface should be applied directly on top of the R10 with the joints glued using a PVA wood adhesive or our own sealant. No mechanical fixings must be used which may penetrate the R10 insulation. A gap of around 5mm should be left around the perimeter of the floor (read specific flooring manufacturers instructions for likely expansion). The flooring chipboard should not touch the walls. This gap should be completely filled with our flexible sealant. When applying skirting boards, allow a 2-3mm gap between the skirting and the top of the flooring. This gap should not be filled unless the material used is flexible and non-hardening.

Load bearing and stud partitions should be constructed from the base floor before the installation of floating floors. Under no circumstances should our R10 be used as a load bearing component.
