Designing, specifying and installing fire rated timber framed butt-jointed glazing is now easier with the assurance of a fully traceable supply chain with the launch of SYSTEMGLAS® Ligna by Promat UK, one of the country’s leading manufacturers of fire, thermal and acoustic solutions.

Joining the existing ‘frameless’, paintable, metal-clad and steel frame options to complete the SYSTEMGLAS® range, Ligna gives designers the ideal balance of assured fire protection and maximum light transmission in all kinds of timber framed glazed partitions and screens. Ideal for offices, healthcare, education, retail and public sector applications, it has been tested (CERTIFIRE CF5452) to provide integrity and insulation (EI) fire protection from 30 minutes up to 60 minutes (EI30 to EI60). All the options are explained in Promat’s UK’s comprehensive new Specifiers Guide, available to download at

SYSTEMGLAS® Ligna’s exact configuration of fire glass and components, including beading and setting blocks, is provided to joinery manufacturers who are fully supported by Promat UK throughout the manufacture stage. This ensures the timber frame is created to the correct specification to deliver the finished glazing’s promised fire protection level.

 It is an approach which ensures that Promat UK provides a 360 degree ‘wheel of assurance’ to specifiers and end clients. Promat UK’s passive fire protection experts work closely with customers at every stage of the supply chain, starting with guidance on the right approach at the design and specification stage. All SYSTEMGLAS® products are then manufactured consistently in its ISO 9001 and ISO 14001 (2015) manufacturing plants with close supervision provided to its partner joinery manufacturers to eliminate risk. This ensures all cutting and processing is completed to the correct standard.

The final stage of the wheel of assurance sees Promat UK inspect SYSTEMGLAS® on completion to check that it has been installed in accordance with its recommendations. The company then provides a certificate of conformity for installation.

Ian Cowley, Regional Director (UK and Scandinavia) at Promat UK says: “SYSTEMGLAS® Ligna takes fire protection in timber framed glazing to a whole new level. For the first time, specifiers can choose a complete system with confidence, safe in the knowledge that all elements of the glazing system are designed and manufactured to work together to deliver the required fire protection. It takes away any ambiguity with Promat specialists maintaining control and reducing supply chain risk by eliminating the points where there could be any deviation in the specification.” 

Part of international building product manufacturing group the Etex Group, Promat UK has been producing fire, thermal and acoustic protection solutions for more than 30 years. In addition to its range of fire resistant glass, the company manufactures market leading high performance solutions which are used in numerous hi-tech, engineering and industrial sectors.
