Fire-Rated Glass

Fire-rated glass saves lives. It maintains the integrity of escape routes and compartments during a fire, holding back flames, smoke and — in insulated grades — radiant heat, while still letting daylight and visibility through. Lord Glazing supplies and installs certified fire-rated glass and glazing across London for offices, schools, hospitals, retail and hospitality buildings. From fire-rated doors and screens to glazed partitions and vision panels, we deliver fire glazing that is fully tested, correctly installed and properly documented. With 15+ years' experience, 5,000+ projects and a 4.9-star reputation, we are a specialist you can trust on life-safety glazing.

Why choose fire-rated glass for your London business

Fire-rated glazing is not an off-the-shelf product — its performance depends on the glass, the frame, the seals and the installation working together as a tested system. Get any element wrong and the rating is void. We install complete, certified fire-rated systems that satisfy Building Regulations and the relevant BS EN standards, providing fire integrity (E) and, where specified, integrity plus insulation (EI) ratings of 30, 60, 90 and up to 120 minutes. This protects occupants, supports safe evacuation, satisfies fire risk assessments and gives building owners genuine compliance. Every installation is carried out by a fully insured team and properly documented for your fire safety records.

As a GGF member, TrustMark approved and Checkatrade verified installer, we bring accredited expertise to critical life-safety work.

Our process / installation

Fire glazing demands precision. We start by reviewing your fire strategy or risk assessment and surveying the openings, then specify a fully tested system — glass, frame and seals as a certified unit. After you approve the quote, the system is fabricated to exact tolerances. Our installers fit it strictly in accordance with the test evidence and manufacturer instructions, install intumescent seals correctly and complete the work to the rated standard. We then provide the certification and documentation you need for compliance, and can programme works out of hours in occupied buildings.

Sectors we serve

We install fire-rated glazing across London's hospitals and care facilities, schools, colleges and universities, commercial offices and high-rise buildings, retail and shopping centres, and restaurants and hotels — anywhere compartmentation, protected escape routes or fire-rated separation is required.

Fire-rated glass across London

We cover all 33 London boroughs. From hospital and education estates in Lambeth, Southwark and Camden to office towers in the City and Canary Wharf and commercial buildings in Croydon, Newham, Brent and Hounslow, our fire-glazing specialists deliver compliant systems throughout the capital. With fire safety under closer scrutiny than ever across London's commercial and public buildings, our documented, certified approach gives building owners, managing agents and responsible persons the assurance they need.

Compliance & building safety

Fire-rated glazing sits at the heart of a building's passive fire protection, and getting it right is a legal and moral responsibility. We install systems strictly in line with their fire test evidence and classification, ensuring the glass, framing, seals and fixings are matched as a certified assembly — never mixed and matched in a way that would invalidate the rating. Our work supports your obligations under fire safety legislation and the building's fire strategy, helping protect escape routes, maintain compartmentation and limit fire and smoke spread. We supply full certification and installation records for your fire safety file, and we are fully insured and GGF members, so you can demonstrate compliance with confidence.

Pricing guide

Fire-rated glass is priced on application (POA) because cost depends on the rating (30 to 120 minutes), whether insulation (EI) is required, the framing system, sizes and quantities. We provide a detailed, transparent quote following survey. Free quotes are available for all enquiries. For related works, see our commercial doors and glass partitions, or contact us to discuss your fire strategy.

Frequently Asked Questions

What fire ratings can you provide?

We supply certified systems offering fire integrity and, where required, insulation at 30, 60, 90 and up to 120 minutes, matched to your building's fire strategy.

What is the difference between E and EI fire glass?

E (integrity) glass contains flames and smoke for the rated period. EI (integrity plus insulation) glass additionally limits radiant heat transfer, protecting people on the safe side and enabling closer escape routes.

Is the glass alone enough to achieve a fire rating?

No. The rating is a property of the whole tested system — glass, frame and seals together. That is why we install complete certified systems strictly to the test evidence.

Will fire-rated glass still let in light?

Yes. Modern fire glass is clear and lets daylight and visibility through, so you keep bright, open interiors while meeting fire safety requirements.

Do you provide certification for compliance?

We do. We provide the documentation needed for your fire safety file, building control and insurers, and we are fully insured with a 10-year guarantee.
