The robust system that offers extreme levels of fire protection

Planet FireStop offers a multitude of solutions to meet even the most stringent of fire requirements. The system is based around 'thermally broken' steel profiles which offer extreme levels of fire protection. The system is inherently robust and will provide long lasting durability in the most demanding applications.

Fire Rating UP TO 120/120 FIXED SCREENS

Maximum Protection

Fixed glazed screens can be provided in many guises, which enables the specifier to meet the design intent in tandem with the fire ratings needed. A firm favourite is butt jointing, which relies solely on head and base tracks with no glass to glass mullions. If a more structured aesthetic is required, FireStop can be formatted to include vertical mullions and horizontal transoms.  This added framing also enables the system to be certified at an unprecedented 120/120 minutes (integrity and insulation) using 58mm thick Planet FireGlass.

01 – Double doors as shown here are on held open devices, that automatically close doors once fire alarm systems are activated
02 – Fixed glazing can achieve up to 120/120 fire rating (integrity and insulation)

03 – Doors can be full height to ceiling, or use fixed glazing overhead as shown here
04 – Double doorset shown, with back to back pull handles. Many other options are available
05 – FireStop framework can be polyester powder coated to any RAL or BS colour
06- Glass to glass joints on Ei30 and Ei60 glazing can be formed by sleek and attractive jointing



The insulated and thermally broken steel framework of the FireStop system is polyester coated to any RAL or BS colour. Ironmongery options are vast and include lever handles, pull handles and also automatic hold open devices. Manifestation and other design options can be applied to the glass, in order to further enhance the look of the system.


FireStop Doorsets

Offering up to 60/60 minutes (integrity and insulation), single, double or ‘leaf and a half’ options are available, in partial or full height sizes. Doors can either be held open, on devices that close in the event of an alarm (ideal in heavy circulation zones), free swinging, or latched closed for added security.

Project highlights

“The FireStop screen range installed at Birmingham City University’s Curzon Street building was an impressive product. It did not compromise on aesthetics over fire rating performance, and worked well with the already designed apertures”.
