When it comes to getting the most glass for your home, sliding doors are the best possible option. Top and bottom running tracks allow for very large door panels, keeping the framing to a minimum and maximising glazing.Sliding doors achieve a perfect halfway house between doors and windows. The expansive view created by the impressive glass sizes and slim sightlines feels more like a large window when the doors are closed. Pair this with smooth sliding operation and you have external doors that tick all boxes.

Different design just for you
Heavy duty sliding door is an optimised, high performing. Thermally insulated sliding door with a slim sightline.The system combines this highly attractive aesthetic line with remarkable energy efficiency,the belongs to an entirely new generation of sliding systems thanks to technical innovation and well-considered design.

Easy to manufacture and install
Frames and sashes are asembled using eccentric,pin or press corners.Stainless steel corner chevrons guarantee a perfect alignment of the corners All profiles are prefabricated using the specially designed punching tools or machining centers.Drainage holes,vent cut outs and the holes punched for eccentric cleats are therefore very precise,ensuring fast and accurate assembly. No punching needed for the installation of the bottom rollers (lift-slide version).

Impressive strength & durability
A combination of strong profiles,stainless  steel rails and polyamide rollers with needle bearings allows sliding door to be used for glazing areas up to 2.8meter high without external reinforcement. The use of a stainless steel rail ensures the smooth movement of the vents and avoids surface finishing pealing off. Polyamide bottom rollers can take up to 300kg for each vent and still ensure a smooth operation.

Advanced Energy saving on modular basis
Heavy duty sliding door  profiles are coupled  with 40mm glas fibre reinforced polyamide strips, which reduce thermal conduction. These polyamide strips are specially designed in order to improve the thermal values, without adding extra internal inserts in the profiles. The bigger cavities between  profiles are insulated with customized PE strips. The result is that heavy duty sliding door achieves a high thermal performance level and improved total insulation. Leading to lower total energy consumption and a reduced environmental impact.
