An advantage of this system is that the aluminium structure allows a different material to be used on either side of the door, which is not possible with traditional wooden doors.

The materials used on the door panels can also be used for the wall facing. The door frame design enables easy levelling and allows a flush aesthetic finish.

This Design line system is characterised by the employment of the highest quality materials and design elements.

• Aluminium profiles pressed by Swedish concern SAPA – a worldwide leader in aluminium production

• Door profile in two anode colours; natural and brushed steel with an enhanced thickness of the layer resistant to scratches.

• The aluminium construction is bonded with a glue made by the Swiss producer Sika – a leader in production of chemical glues.

• Hinges are regulated in 3 planes and are certificated by IFT Rosenheim institute (200,000 thousand opening cycles)

• Magnetic-mechanical lock made by KFV, a German producer.

• XPS filler made by DOW Chemicals enhances the thermal and acoustic insulation as well as improves the wing stiffness.

The use of materials made by renowned producers ensures that the Design Line System is of the highest quality and will offer endurance, safety and comfort.

The light aluminium construction allows the door to reach heights of up to 3000 mm and the makes the use of heavier finishing materials possible.

The Design Line system can be fitted with additional elements:

• hidden door closer GEZE

• drop seal

• Assa Abloy door lock

• various types of locks (with sub-bullet points of WC locks, insertion, key)
