Celotex Floor Applications

1 Cement floors

The specification of insulation for ground floors is more complex than that for walls or roofs. This is because the mechanisms for heat flow are affected by the ratio of surface area to perimeter.

Optimum positioning of the insulation within the floor may depend on the positioning of the insulation in the walls. For instance, when insulating dry lining is specified for the walls, over-slab insulation enables continuity of insulation to be achieved.

In over-slab installations, such as solid oversite slabs and, more particularly, exposed solid slabs, use a vapour control membrane over the insulation to eliminate any risk of condensation forming on the cold slab surface.

2 Underfloor Heating

Underfloor heating is now recognised as one of the most efficient and cost-effective forms of domestic heating. For maximum efficiency it requires effective insulation beneath the heating elements to minimise heat loss downwards into the structure and to reflect the heat upwards into the room. Celotex fast-R FF3000 insulation is the ideal solution. Underfloor heating systems are used in approximately 50% of all self-build homes and increasingly in extension and conservatory projects. Many underfloor heating companies already make use of the high performance characteristics of Celotex insulation.

When extending a building, adding underfloor heating to the existing heating design can bring major benefits especially in applications, such as conservatories, where it is difficult to position standard radiators and an underfloor heating system is possibly the only acceptable form of heating.

3 Suspended Timber Floors

With a suspended timber floor, there is little choice but to install the insulation between the joists, but the thermal bridges created by the joists have to be considered.

Continuity of the insulation must be ensured by packing the spaces between the external walls and the joists with insulation.

The void below an insulated suspended timber floor must be well ventilated. The insulation must be cut to fit tightly between the joists to prevent heat loss.

4 Beam and block Constructions

With a beam and block floor, there is little choice but to install the insulation over the floor before screeding. The ventilated air space beneath any suspended floor can be very cold, so Celotex recommends the application of a continuous vapour control membrane over the top of the insulation, before screeding, to reduce the risk of condensation forming at the insulation/slab interface. This also prevents screed migration between the board joints, thus avoiding cold bridges. Use Celotex Tough R GA3000z range
