Order Aluminium Bi-Folding Doors

Trickle vents included as standard.

From the 15/06/2022, the Building Regs state that trickle vents are required on practically all glazing elements. Unless otherwise specified we will include trickle vents in pre-determined locations as standard. On bi-folding, trickle vents are fitted into a 42mm add-on above the outer door frame. If a certain rate of 'equivalent area' is required, please include instructions
If trickle vents are not required, please tick below. Please note trickle vents cannot be retro-fitted.
