Hinged Glass Fire Doors & Fixed Windows

*ROCKLITE® ‘S’ glass fire doors are easy to install. They are manufactured in a wide range of sizes to match existing applications.


*ROCKLITE® ‘S’ fire doors are supplied with a purpose-made 3mm steel frame with a 20mm rebate including 2 bullet hinges per leaf. Frames are tubular frames and gets bolted onto existing wall openings.


  • 6mm Schott PYRAN® S Borofloat Toughened Glass for a 120 minute fire rating is used in all our Glass Fire Doors. Between the Glass & Steel Glazing Beads we include Intumex® LPSK Intumescent Strips

  • 6mm Toughened PYRAN® S Borofloat Glass - 30 to 120 minutes

PYRAN® S is a superior fire resistant glass with a fire rating of up to 120 minutes if used in conjunction with a steel frame or door leaf.


PYRAN® S is manufactured using a micro-float process and outperforms soda lime glass. It allows for large formats and long fire resistance times due to its special physical properties. Furthermore, NiS crystals cannot form with Borosilicate glass. Borosilicate glass is the base material for the entire PYRAN® family of fire resistant glazing products. The standard PYRAN® design consists of a monolithic borosilicate glass, refined by thermal tempering and manufactured in a Microfloat facility, the only one of its kind in the world. This unique combination of borosilicate glass and the float process results in a specialized glass with outstanding characteristics.


Amongst the entire range of SCHOTT fire resistant products, PYRAN® S offers the greatest multi-functionality. PYRAN® S is a monolithic thermally tempered borosilicate safety glass according to DIN EN Standard 13024-1. PYRAN® S is a regulated building material and can be used for single or double glazing without conducting the heat soak test, giving it yet another advantage in terms of safety and dependability.


Even when exposed to severe heat, PYRAN® S glass remains transparent, this ensures lifesaving viewing making it safer in the event of an emergency evacuation.


PYRAN® S characteristics include:

*high transmission in the visible and ultraviolet spectral ranges

*brilliant optics, ensuring natural, pure colour reproduction


​PYRAN® S demonstrates extreme durability against:

*aggressive environmental atmospheric attack

*exposure to UV radiation

*abrasive chemical solutions

We specialise in the protection of buildings from fire by the insulation of structural members, walls and tanks against direct attack from flames by maintaining load-bearing members and tank-shells below the critical point at which failure or weakening is likely to occur.
