- Tested fire-rated curtain wall systems
What every Chelmsford quote includes
England rules applied
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
Work around occupied buildings
We can phase work in Chelmsford around residents, staff or pupils, with out-of-hours options.
Honest about unknowns
If an existing frame in a Chelmsford building has no traceable evidence, we say so and price the options rather than guess.
Before you order fire-rated curtain walling: what matters
External-grade glass
External fire glass must be suitable for UV and weather exposure, usually in a sealed double-glazed unit with the fire pane positioned as tested.
Boundaries
External walls close to a boundary may need to be fire-resisting with limited unprotected areas. Fixed glazing that meets the wall's full fire-resistance requirement, including insulation where required, is not counted as unprotected area, so it can let you keep glass in those positions.
Thermal and acoustic
Fire-rated units can still meet thermal targets when specified correctly; we confirm U-values with the system supplier.

Fire glazing rules 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.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
Building types we cover in Chelmsford
Fire-rated curtain walling applies to many building types in Chelmsford, including industrial units and healthcare buildings.
Fire-Rated Curtain Walling: Chelmsford questions
When does curtain walling need to be fire-rated?
Typically where the facade is near a boundary, where it encloses a protected stair or lobby, or where fire spread between floors has to be controlled. The fire strategy sets the requirement.
Can you add fire-rated zones to existing curtain walling?
Sometimes, if the existing system has a tested fire-rated version. Otherwise a local replacement may be needed.
How quickly can you survey in Chelmsford?
Survey timing in Chelmsford depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Do you work on occupied buildings in Chelmsford?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
