Underfloor Heating.Timber floors and underfloor heating make for the perfect combination. But...
Underfloor heating is the most demanding environment for timber floors. It is very risky to lay solid timber floors over underfloor heating: the timber will cup, split and shrink. The floor must be engineered. This means a structural bonding of layer materials with very low movement factors.
We use 12mm 9-layer 100% birch throughout ply as the core. This is more stable than any other core. Even so, from winter to summer the floor will move slightly, so our boards are allowed to move accordingly. This is particularly vital for flooring over underfloor heating.
Underfloor heating buried in the screed can be used to dry out the screed, but it will take some time. Check with the manufacturers of both products. It is preferable to not include additional water in the construction and, instead, use extruded polyurethane or dense polystyrene as an insulating layer that receives the hot water pipes or electric mat. Our floor then sits directly on this.
The upper surface temperature of our floor must not exceed 28° C. The maximum working temperature of the water is 33° C. Make sure suitable controls are fitted for this.
Underfloor heating must be installed, fully commissioned and controlled at least a week prior to installation. Allow the flow temperature of the water to increase from ambient to 28° C at 2° C per day, and then leave the system running at 28° C.
We will lay the floor over the operating underfloor heating. This helps prevent the floor taking up moisture from the building before it fully dries out. Leave the heating on low until the client takes possession of the building.
Electric underfloor heating must be controlled so that the top surface of our floor does not exceed 28° C.
We are happy to advise on underfloor heating and its requirements.
Acoustic insulation.Timber floors can be noisy. Reducing the noise may be vital great care should be taken.
Timber floors can have impact sound and airborne sound reduction incorporated prior to and during laying.
