Insulated Fire Glass (EI)
EI 30 to EI 120 glass that blocks heat as well as flames.

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.
The fire strategy or building control drawings set the rating for each element. Integrity-only glass is cheaper and thinner, but its use on escape routes is restricted; insulating glass carries far fewer restrictions because people can pass it safely during a fire.
Most fire glass is permanently marked with its product and classification. We record the marks, pane sizes and evidence references on handover so whoever is responsible for fire safety can show what is installed.
Our Hertfordshire coverage takes in Hemel Hempstead (HP3, HP2, HP1) and the neighbouring towns of Berkhamsted, St Albans, Harpenden. Hemel Hempstead lies roughly 12 km from Watford, within our Hertfordshire coverage.
Every quote in Hemel Hempstead identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
If an existing frame in a Hemel Hempstead 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.
We can survey and quote for schools and colleges, offices and other building types in Hemel Hempstead.
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.
Integrity glass can be similar in thickness to standard glass. Insulating glass is laminated from several layers, so it gets markedly thicker and heavier as the rating increases from EI 30 to EI 120.
Yes. We survey and install in Hemel Hempstead and across Hertfordshire, including the HP3 district and nearby Berkhamsted.
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
