Floating Floor System

The REHAU Floating Floor system is suitable for domestic as well as commercial applications. For domestic applications this can be chipboard or plywood, for commercial installations we recommend 25mm thick dry flooring elements.

Extruded polystyrene panels are pre-routed in different patterns and are laminated with a strong aluminium foil. The foil diffuses the heat uniformly across the entire floor surface, the response time is significantly reduced compared to traditional wet screed systems due to the lower thermal mass.

Floating Floor installations using the single meander pattern are possible on both solid and suspended substrates. The REHAU Floating Floor system utilises the REHAU RAUTHERM Universal pipe 20mm x 1.9mm.

All floating floor panels are made from extruded Polystyrene XPS. Each panel feature a rebate to create an interlocking floor. They are supplied in a standard size of 1.25m (L) x 0.6m (W) x 30mm (H) and are available in four variants:

• - Straight Panel (foil faced)
• - Highway Panel (no foil)
• - Curve A Panel (foil faced)
• - Curve B Panel (foil faced)

Highway panels are used for all connecting lengths of pipe and to connect the pipework to the manifold.

Floor Preparation
The ground must be sufficiently level before the system is installed. To overcome unlevel ground a dry levelling compound can be placed onto REHAU PE membrane followed by a 10mm dry flooring element. This provides a clean solution without the introduction of any wet trades and can compensate for differences in floor height of up to 60mm.

When installing the system onto a suspended timber floor, ensure the floor structure is solid enough to withstand the intended load without deflecting or flexing. Check the structural integrity of the floor and make any defects good (i.e. screw down all loose floorboards).

Distribution Layer To distribute the intended loads uniformly across the Floating Floor panels a distribution layer must be laid. For domestic applications this can be chipboard or plywood, for commercial applications it is recommended using 25mm Dry Flooring Elements, which are glued together at the joints to create a uniform floor (See flooringmanufacturers guidelines). For commercial applications with higher traffic loads, a second layer of 10mm Dry Flooring Elements can be bonded on top (see flooring manufacturers guidelines).

Additional insulation
To meet current Building Regulations, some installations may require additional insulation. Extra insulation panels can be laid underneath the floating floor panels at a 90° angle. However, it is important to check that the insulation is suitable for the intended point loads

REHAU Routing Tools
The REHAU routing tool allows easy and quick customisation of panels. It is mains operated and features a hot blade specially shaped to cut the correct groove into the Floating Floor panels. Its size makes it the ideal solution for tight pipe bends and where grooves have to be cut close to a wall or corners.
