This guide will provide a step by step procedure to use SuperQuilt Insulation on Concrete Floors. SuperQuilt is proven to save on cost, space & installation time compared to Rigid PIR Insulation. PIR manufacturers include Kingspan & Celotex. SuperQuilt is fully LABC & BDA certified for Solid Concrete Floors. The multi-layered blanket can commonly achieve building regulations stand-alone in floors.

Method steps

1. Installing first run of SuperQuilt

SuperQuilt can be rolled out vertically or horizontally along the concrete floor. Leave enough material at the edges to protrude SuperQuilt Insulation above the floor deck. Ensure the concrete floor is fully clean, flat, and debris free.

2. Joints and Taping

Ensure SuperQuilt is butt jointed with other layers on both the verticals and horizontals. (No overlaps). Fully tape and seal all butt joists of SuperQuilt with Thermaseal 75mm ThermaSeal Foil Joining Tape.

3. Installing Battens

Timber battens or joists are then laid over the top of SuperQuilt - at 400mm centres (evenly spaced). The minimum batten depth is 50mm, increasing the batten depth enhances the performance. SuperQuilt will compress to around 7mm when timber is installed above.

4. Finish with Flooring

Proceed with installing your timber boarding floor. The deck is then fixed at 200mm centres, with 37mm screws into the joists or battens below
