Fire-Rated Acoustic Glass

What is fire-rated acoustic glass?

Fire-rated acoustic glass is engineered to:

• Maintain fire integrity and, where required, insulation for a defined period
• Reduce airborne sound transmission between spaces
• Meet impact safety and building regulation requirements
• Integrate into certified framing systems without additional counterpanes

It’s commonly specified in education, healthcare, commercial offices, transport hubs and mixed-use developments where fire protection and noise control are both top priorities.

Pyroguard glass for fire-rated acoustic applications

Designers and specifiers often look for fire-rated acoustic glass when compartmentation, privacy and comfort are all part of the brief. In these scenarios, glass must do so much more than simply resist fire. The specified glass would need sufficient mass and construction flexibility to limit airborne sound, while remaining clear, safe and compliant.

Pyroguard fire safety glass is regularly used in these applications because it can be configured to deliver meaningful noise dampening alongside tested and certified fire performance. Depending on the system and implementation, Pyroguard glass can achieve sound reduction values typically associated with acoustic glazing, without introducing unnecessary complexity to the specification.

Two Pyroguard ranges are particularly well suited to these requirements: Pyroguard Protect and Pyroguard Infinity. Each supports different design priorities, from extended fire resistance and external use through to seamless internal partitions.

Pyroguard Protect

Pyroguard Protect is often specified where a project demands robust fire performance alongside improved acoustic control. Its thickness range and compatibility with laminated constructions make it a strong option for spaces where noise reduction is important, such as classrooms, meeting rooms, healthcare corridors and mixed-use developments.

In acoustic terms, Pyroguard Protect can achieve sound reduction values typically in the region of 39-47 dB without modification, but far greater sound attenuation may be achieved by adding specialist counterpanes as a laminated version (VF), double-glazed (VI) or triple-glazed (TVI). This level of performance supports privacy and concentration without the need for secondary glazing or additional counterpanes.

Fire performance remains the primary function of the glass. Pyroguard Protect is available with EW and EI classifications, offering fire resistance from 30 minutes up to 180 minutes. This makes it suitable for both standard compartmentation and higher-risk areas where insulation against heat transfer is required.

The range is designed to integrate easily into common framing systems and building types. It can be used internally or externally, as single glazing or within insulated glass units, and is certified for use in steel, timber and aluminium profiles. This flexibility allows acoustic and fire objectives to be addressed without compromising the wider façade or interior design strategy.

Alongside its fire and acoustic capabilities, Pyroguard Protect offers impact safety, UV stability and long-term durability, supporting consistent performance wherever it’s implemented.

Pyroguard Infinity

Pyroguard Infinity is frequently chosen for internal spaces where fire-rated glass must also support clean lines and open visual connections. Its certification for butt-joint applications allows designers to create near-seamless glazed partitions without intermediate vertical framing.

In terms of acoustic performance, this glass can contribute to sound reduction levels typically around 38-44 dB, helping to isolate noise between rooms, corridors and open spaces again these products may be modified to achieve even more impressive levels of sound reduction. This makes it a great option when acoustic-rated fire glass is required for offices, education buildings and healthcare environments where both visibility and acoustic separation matter.

Infinity provides EI fire resistance for 30 and 60 minutes, maintaining integrity and insulation in critical internal zones. It can be supplied as part of a complete, tested glazing system, simplifying specification and installation while reducing risk on site.

High light transmission is a key benefit, allowing natural light to pass through spaces and supporting modern interior design objectives. The result is a fire-resistant glazing solution that meets acoustic needs without the visual weight often associated with traditional fire partitions.

Typical applications for fire-rated acoustic glass

Fire-rated acoustic glass is commonly specified in buildings where noise control, safety and transparency all influence the user experience. Pyroguard solutions are regularly used in:

• Education buildings, including classrooms, lecture theatres and learning hubs
• Healthcare environments such as wards, consultation rooms and circulation corridors
• Commercial offices, meeting rooms and collaborative spaces
• Hotels and residential developments where privacy is essential
• Transport hubs and public buildings with high levels of background noise

Each Pyroguard system can be tailored to suit the fire strategy, acoustic expectations and framing requirements of the project, ensuring compliance without unnecessary over-engineering.

Specification support and technical advice

Selecting the correct fire-rated acoustic glass depends on fire strategy, acoustic targets, framing and building use. Pyroguard provides:

• Project-specific specification support
• Certified test evidence
• Advice on glazing configurations and system compatibility
