Welcome to Avesta ARCHITECTURAL ALUMINIUM SYSTEM.

Due to high customer demand, avesta has newly designed Visions Fold, a bi-folding door system. As a leading bi-fold systems company, the profiles are designed with security and thermal insulation as it's design core. Constructed with light weight aluminium, it provides a clean and visually pleasing finish to any building exterior.

Profiles are designed to be slim as possible, without compromising security and thermal insulation. This design enables the greatest amount of natural light to enter through the doors.
We work together with fabricators and the end user to ensure the end product has been designed to accommodate all positive design aspects, and eliminate the negative points.
System incorporates 3 point door locking, shootbolt locking, external rebate for all panes, internally beaded and 32mm thermal break.
Testing:
Vision fold has undergone rigorous testing to ensure a long lifspan. Test to 10,000 cycles and fully weather tested.
Energy Performance:
With a double glazed unit, the system achieves a U-value of 1.7. Surpassing current requirements of 1.8. With adititonal materials, the system can achieve even lower results.
Materials used:
Aluminium: produced at EN-AW-6063 AlMgSi, AA 6063/A, SS-EN-AW-6063/A to T6. Light weight profiling and locking its physical strength.
Themalbreak:
a large 34mm thermal break, produced with polyamide 6.6 with 25% glass fibre content to give it strength while maintaining resistance to heat flow.
Sealing:
EPDM with double chamber design to conserve heat and ristance to water. giving a W/(M.k) value of only 0.25. Fold gasket incorperates a child finger protection system.
Finishes:
Powder coating: coated to BS EN12206:2004 in various RAL colours. Painted to QUALICOAT License 1003. Dual colour option available
Anodized finish: hard protecting on top of aluminium eliminating aluminium oxide. Giving it the natural aluminium finish. Silver as standard.
Manufacturing:
Joining: profiles are mitre cut at 45 degrees and then bonded and bolted together with corner cleat inserts and cheverons for added stability.
Hinges: Specially designed hinges to fit the profile, with bottom rollers and top rollers.
Sealing: rubber gaskets are fitted at glazing points and throughout the sash framing.
Flippers gaskets are fitted at folding stiles with a large clearance as a anti-finger protection.
Foaming:
EPS foam is used on the frame for insulation and GA25 mid-density foam is used in fold stiles for greater insulation.
