Insulated Fire Glass (EI)
EI 30 to EI 120 glass that blocks heat as well as flames.
Learn more →From the SP1 district outwards, we arrange fire-resistant glass for buildings across Salisbury, matching glass, frames and seals to tested evidence rather than guesswork.

Fire-resistant glass is glazing that has been tested, as part of a complete glazed system, to hold back fire for a set time. It is classified by what it stops: E (integrity) keeps flames and hot gases on the fire side, EW also limits the heat radiated through the glass, and EI (integrity and insulation) also limits the temperature rise on the protected side, so people can pass it more safely.
Glass in doors, side panels and low-level positions has to meet impact safety rules as well as the fire rating. Most modern fire glass carries an impact classification; old wired glass usually does not.
No. A frame is only rated with the glass types and pane sizes it was tested or assessed with. We check the frame's evidence before quoting, and if the existing frame is unknown we say so and price the options.
Many insulating fire glasses use interlayers that need protecting from UV and moisture, so external positions need a product approved for exterior use, with the right edge seal and glazing system.
Survey visits can be arranged anywhere in Salisbury, including the SP1, SP5 districts, and in nearby Andover, Totton, Southampton. Salisbury is about 54 km from Swindon, the largest town in our Wiltshire coverage.
After survey you get a fixed written quote for the agreed scope, so Salisbury budgets are not open-ended.
We can phase work in Salisbury around residents, staff or pupils, with out-of-hours options.
If an existing frame in a Salisbury building has no traceable evidence, we say so and price the options rather than guess.
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.
Sector guides below cover public buildings, industrial units and other buildings in Salisbury.
Ordinary toughened safety glass is not. It can shatter early in a fire. Fire-resistant integrity glass is specially processed or formulated and only gains a rating when fitted in a tested frame and glazing system.
Our service is supply and installation, because the rating depends on how the glass is fitted. For trade buyers we can quote supply of cut-to-size panes with the matching glazing materials on request.
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
Yes. We survey and install in Salisbury and across Wiltshire, including the SP1 district and nearby Andover.
