Technical specifications

Technical specifications

For decking, it is a non-load-bearing rail designed to be laid directly on the ground or screwed onto a structure for raised installation. The possible finished heights with this type of structure are between 39 and 47mm.

The Flat rail can be used for exterior cladding for invisible board fastening, offering an aesthetic finish without visible screws. It allows for the precise and regular installation of wood coverings, while ensuring efficient ventilation of the facade. Suitable for boards approximately 20 mm thick, it integrates into cladding configurations reaching up to 38 mm total thickness, guaranteeing durability, stability, and quick installation on site.
The Flat rail is also suitable for soffit, ceiling, and interior wall covering installation, allowing for aesthetic continuity of arrangements.

Instructions for use

Place the Elastomer strip under the rail.

This addition will compensate for level differences and eliminate all parasitic noises.

Then, place the rail directly on the ground.

Finally, fix the rail to the ground using nail anchors.

The Flat rail can be used in conjunction with other load-bearing elements such as a beam (wood/metal*), joists, or other UR-type rails.

*When installing on a metal beam, a Elastomer strip should be placed under the Flat rail.

For vertical or horizontal cladding, place your rail every 65 cm and fix them.

The Flat rail can be fixed directly to the ceiling.
