Schlüter-DILEX-BT/VTS  Support profile for structural movement joint

Schlüter-DILEX-BT/VTS is a maintenance free support profile made of aluminium for retrofitting in finished coverings. The sliding telescopic centre section DILEX BT/VTS is able to absorb movements of ± 5 mm. The lateral joints connections absorb three-dimensional movement.

DILEX-BT/VTS offers secure edge protection for coverings exposed to high foot and vehicular traffic and is, therefore, suited for use in warehouses, production facilities, shopping centres, airports, train stations, car parks or for floor surfaces maintained with cleaning machines. The profiles can also be installed in wall and ceiling surfaces made of gypsum plasterboard or in plastered and tiled surfaces.

Schlüter-DILEX-BT/VTS is designed for retrofitting in the structural movement joint. The joint must be at least 44 mm wide and 10 mm deep. Fully embed the lateral anchoring legs in the respective adhesive (e.g. epoxy resin) on the existing covering or drill a hole in the anchoring legs and attach the profile to the covering with screws. Depending on the attachment or anchoring, DILEX-BTS has limited mechanical strength. Flush installation within the covering is recommended for surfaces with conveyor vehicle traffic.

The profile is available in the following materials:

• A = aluminium
• AE = anodised aluminium

Material properties and areas of application

The suitability of a proposed profile type must be verified based on the anticipated chemical, mechanical and/or other stresses.

Schlüter-DILEX-BT/VTS is made of aluminium and must be tested to verify its suitability if chemical exposure is expected. Aluminium is sensitive to alkaline media. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and time of exposure) may result in corrosion (aluminium hydroxide formation). Adhesive or grout residue must therefore be removed immediately from visible surfaces.

DILEX-BT/VTS in the anodised aluminium version has an anodised surface finish that will not change under normal circumstances.

The surface, however, must be protected from abrasion. Tile adhesive, mortar and grout can scratch the surface of the profile; therefore, any residue must be removed immediately. Otherwise, the description regarding aluminium applies.
