Before you order in Northamptonshire
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.
Escape windows are different
Windows used for escape from rooms have their own size and opening rules, and should not be confused with fire-resisting windows.
Matching appearance
Rated windows can usually be finished to match the rest of the elevation.
England rules for fire glazing
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.
Questions from Northamptonshire clients
Do fire-rated windows look different?
Frames can be slightly heavier, but most can be finished to match surrounding windows.
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.
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 you survey anywhere in Northamptonshire?
Yes. We can arrange surveys anywhere in Northamptonshire, including Northampton and Corby, Kettering, Wellingborough, Rushden.
