High Performance Fireproof Windows for Light, Safety, and UK Compliance
Fireproof windows are a critical part of modern fire safety systems, offering both visibility and passive protection. Designed to resist high temperatures, they help slow the spread of fire and smoke — giving occupants time to evacuate and allowing emergency responders to act. At the same time, they provide natural light and clear sightlines, making them ideal for buildings that require both safety and transparency.
Fire rated windows are especially important in multi-storey buildings, where vertical fire spread poses serious risks. By acting as a barrier between compartments, fire rated windows help contain flames, heat, and smoke — protecting escape routes, separating high-risk zones, and reducing structural damage.
At FireResist, fireproof windows are manufactured using advanced materials and proven fire-resistant technologies. We combine strengthened laminated fire resistant glass with durable steel or aluminium frames. Many of our systems use intumescent interlayers — specialist materials that expand when exposed to heat, increasing thermal insulation and delaying the transfer of fire and smoke. Glass options include wired glass, tempered glass, and multi-layer glazing systems tailored to performance and appearance needs.
Double-Glazed Fireproof Windows with Acoustic Isolation
Modern fireproof windows can also incorporate double-glazing, combining two panes of fire-resistant glass separated by a cavity filled with air or inert gas. This not only improves thermal insulation, but also enhances acoustic performance — reducing noise transfer between rooms or from external noise. In schools, hospitals, hotels, and urban residential buildings, this dual functionality is critical.
Double-glazed fire rated windows are engineered to maintain fire integrity without compromising other performance areas. The cavity between panes may include intumescent materials or reinforced layers, ensuring the entire unit meets fire classification requirements such as EI30 or EI60.
Improved sound insulation helps create more comfortable environments, particularly in busy settings or sensitive areas such as offices, patient rooms, or educational facilities. With correct installation, fire rated windows can achieve Rw ratings of 40 dB or more, significantly reducing unwanted noise while still providing compliant fire protection.
Whether your project demands quiet, privacy, or thermal efficiency, our double-glazed fireproof windows offer a well-rounded solution that balances safety, comfort, and energy efficiency — without compromising on legal or architectural requirements.
Where Can Fire Rated Windows Be Used?
- Residential buildings – to protect escape routes and separate flats in apartments or dormitories.
- Commercial properties – such as offices, hotels, and shopping centres, where they isolate fire-prone areas like kitchens or storage zones.
- Hospitals and public buildings – including schools, kindergartens, and care homes, where both visibility and safety are essential.
- Industrial facilities – to protect machinery and equipment in manufacturing zones.
How to Maintain Fireproof Windows?
To ensure long-term reliability, regular inspection and care are essential. Fire rated glass and frames must be free of cracks or visible damage, as even small flaws can reduce performance. Intumescent seals and gaskets should be checked for wear, and hardware like latches or closers must work smoothly. Cleaning should be done with non-abrasive materials to avoid damaging fire-resistant coatings.
Fireproof Windows Are Tested, Certified, and Compliant
Fireproof windows in the UK are rated by how long they resist fire and heat — commonly classified as EW30, EW60, EI30, and EI60. These ratings indicate performance under exposure to both flames and radiant heat. All FireResist products are tested to meet and exceed UK and international standards, including BS EN 1364-1, BS 476-20/22, and the Regulatory Reform (Fire Safety) Order 2005.
We design every fire rated window to meet strict criteria for integrity, insulation, and smoke control — providing safety without sacrificing natural light. Whether for residential, commercial, or industrial use, our windows deliver dependable protection and complete peace of mind from installation through to everyday use.
