The Visofold series of folding doors from Smart Systems is mostly used in private houses, stores, hotels and restaurants, in order to open a complete wall to create a larger space in the summer season. The system can also be utilised in conservatories as a screen which you can open completely to enjoy the lazy summer days.

Aluminium: Constructed of aluminium alloy extrusion to BS EN 755, extruded from 6063 T6 alloy.
Co-extruded profiles: According to DIN 7863, TV110, BFP 85301, ISO 3994, tested and approved according to an artificial ageing test of "Plexi glass" combined with vulcanised rubber.
Thermal break: Polyamide strips PA 6.6.25% reinforced with glass fibre.

Finishing

Electrostatic Powder coating: According to the guidelines of A.P.A.- Qualicoat in most of the current RAL-colours. The composed profiles (with thermal break) can be coated with different inner and outer colours (Dual Colour). Anodisation in satin or bronze colours with EWAA/EURAS-Qualinod quality label.

Also available in woodstructure finish to imitate different woodstructures (Powder coated according to Qualicoat standards).

Thermal break

The profiles consist of 2 aluminium extrusions which are separated from one another by polyamide strips PA 6.6.25 reinforced with glass fibre. A gluing thread, rolled and pushed in together with the thermal break profile ensures a strong adhesion after melting and flowing, when the profiles are heated in the hardening furnace.
