RAUFIX/Railfix System
This system ensures that uniform circuit patterns are easily achieved and simplifies the installation process in larger areas.
Orkney Housing Association 
The REHAU range of RAUTHERM pipe in sizes 16mm x 1.5mm and 20mm x 1.9mm are fully compatible with the RAUFIX/Railfix system.
REHAU also offer the Railfix System. This system is an alternative to RAUFIX. The installation method follows that of RAUFIX, with the exception of using Railfix rails rather than RAUFIX. Railfix is supplied in 3m and 4m lengths for 16mm or 20mm pipe sizes.
The RAUFIX rail is manufactured from Polypropylene and its unique pipe clip design makes it universal for both REHAU pipe sizes -16mm and 20mm. The function of the rail is to secure the underfloor heating circuits in the planned pattern prior to screeding. The RAUFIX rails are supplied in 1m lengths and there are two variants:
It is placed on top of the polyethylene membrane and fixed securely onto the EPS floor insulation by using the plastic staples or barbs. The rails must be placed 800mm from walls and obstacles and spaced at 1m centres. The RAUFIX rail also features an integrated clip which makes connecting rails together simple and easy without the need of a tool.
Railfix Rail
The Railfix rails are manufactured from recycled polymer and are available for both REHAU RAUTHERM pipe sizes - 16mm and 20mm. The Railfix rail is notched at 50mm intervals to accept the pipe and is placed 800mm from walls and obstacles, spaced at 1m centres and must be fixed with staples every 400mm. The rails are manufactured with a break point at 100mm centres to facilitate easy installation.
Staples
The REHAU RAUFIX/Railfix staples are available in two sizes - 50mm and 40mm. The size of staple used will depend on the thickness of the EPS floor insulation. For 25mm EPS floor insulation the 40mm staples should be used and pushed in through the rail at alternating angles. For 50mm EPS insulation it is recommended to use the 50mm staples. Trim offs from the rails can also be used to fix the pipe bends to the EPS floor insulation.
