The underfloor insulation is designed to suit our timber floor. The rigid 25mm thick insulation boards are suspended between the floor joists and above the ground. The top face of the insulation is just below the floorboards.
The solidity of the floor is unaffected by this design. The internal appearance is also unchanged with attractive and durable tongued and grooved boards. Sufficient fixings are supplied to ensure that the insulation is suspended at the optimum height. Detailed instructions are supplied. The floor insulation used is 25mm thick polystyrene which is certified by the British Board of Agrement.
