More unique features
Our bifold doors, sliding doors and glazing systems are designed and manufactured with features that make them unique - just like us!
The phrase 'we lead, others follow' has never been more appropriate than with our glazing products. Being a technically led company that has been in the industry longer than most of our competitors there is a good chance that features that are now industry standard were first seen on one of our bifold doors or sliding door products - and the constant research and development that we carry out ensures that our products will continue to lead the market for years to come.
Unlike our competitors, IDSystems are technically lead.
We strive to give our customers information that is important to them. That is why our systems are fully tested with weather performance credentials and U-Value statistics (our quoted U-Values include the frame work – other companies may quote just the glass which is misleading).
All our systems meet or exceed the requirements for building regulations with our SF75 bifold doors system achieving a U-Value of less than 1.0 W/m²K and a severe weather rating - when used with the weathered track option, providing a top and bottom double-rebated seal.
High Weather Performance
But U-Values only measure thermal loss, not the effects of wind and rain...which in the UK we experience a fair amount of. To truly test the weather performance of the doors independent weather ratings testing is required.
With the SF75 bifold doors the unique triple gaskets provide a finger cushion and eliminate draughts. These gaskets, along with the manufacturing quality of the system means it achieves EN12206-11 – Air Permeability Class 4, Water Tightness Class 9A (900Pa) and Wind Resistance Class 4 (600Pa) – the best combined achievement of any folding sliding door system on the market today.
Unique vent position
Another unique feature, and an innovative one at that. The SUNFLEX bifold doors, including all aluminium, timber and composite systems, have an integrated vent position when closed.
When you do not want to open up an entire door panel but still wish to have ventilation into the room, the lock part vented position is the ideal solution. Pairs of panels can be part opened allowing ventilation but still providing security with the lead door remaining locked.
High security locking
Lead door or single pass door fitted as standard with a five lever key-locking cylinder, incorporating mushroom headed ESPAG bolt and shootbolts top and bottom. A central latch position can be added for convenience with a horizontal stainless steel lever handle.
First opening pair (or alternative lead door) consists of a two-point top and bottom shootbolt mechanism. The locking system is incorporated within the framework within each intermediate panel, operated by an internal flush handle. For improved security all Sunflex bifold doors systems are internally glazed as standard with centre secured locking hinge pins and interlocking gaskets.
Where there are an odd number of panels, a five-lever profile cylinder is fitted to the end lead door; or to the first opening pair in an even number of panels. It can be fitted to either the inside only or both internally and externally, meeting the requirements of the Association of British Insurers.
