Fire-Rated Windows: what you get in Dorset
Most fire-rated windows are fixed lights, because opening windows need the opening sash, hinges and locks to be tested too. We supply and install fixed and, where tested, opening fire-rated windows in steel, aluminium and timber, matched to the surrounding windows where possible.
- Fixed fire-rated windows
- Tested opening fire-rated windows where available
- Matching sightlines to adjacent non-rated windows
Before you order in Dorset
Why fixed lights are common
An opening sash introduces gaps and hardware that all need testing. Fixed fire-rated windows are simpler and more widely available.
Boundary distance
The closer a wall is to a boundary, the less unprotected area it can have. Fixed windows that meet the wall's full fire-resistance requirement, including insulation where required, are not counted as unprotected area; integrity-only glazing generally still is.
Retrofits
Replacing a non-rated window near a boundary is often triggered by an extension or change of use. We survey the opening before quoting.

Which rules apply in England?
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
Fire-Rated Windows in Dorset: questions
Is fire-rated glass in a standard window enough?
No. The frame, glazing system and fixings also need to be part of a tested window.
Can fire-rated windows open?
Some can, if the opening version has been tested. Fixed fire-rated windows are more common.
When do I need a fire-rated window?
Usually when a wall is close to a boundary, when a window overlooks a protected escape route, or when part of a building faces another part at close range. Your designer or building control will confirm.
Which parts of Dorset do you cover?
All of it: Bournemouth, Poole, Weymouth, Christchurch and every district in the BH, DT, SP, GY postcode areas.
