Before you order in Gwynedd
Closers and gaps
Self-closing devices and correct gaps are part of the performance. We set them at installation and record them.
Doorset, not just a door
The safest route is a complete doorset with frame and hardware tested together. Mixing a leaf from one source with a frame from another needs evidence that covers the combination.
Glazed area limits
Each door design allows a maximum glazed area and aperture positions. Bigger glass needs a door tested for it.
Wales rules for fire glazing
Wales Which rules apply?
Building regulations are devolved in Wales, so fire safety design follows the Welsh Ministers' version of Approved Document B rather than the English one, alongside impact safety guidance for glazing.
The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, so the responsible person must maintain fire-resisting glazing as part of the premises' fire safety measures. The Fire Safety Act 2021 confirmed this extends to the structure, external walls and flat entrance doors of multi-occupied residential buildings.
