Contemporary fire rated glazing system with timber framing

SYSTEMGLAS® Ligna is a timber framed butt jointed fire resistant glazing system designed to match contemporary or traditional environments. Suitable for combination with tested timber doorsets, this solution combines the natural beauty of a timber product with the functionality of a fire protection system. 

Unlimited runs of aesthetically pleasing butt jointed glazing can be installed to maximise light transmission and create a contemporary design without compromise to fire protection. It has been tested (CERTIFIRE CF5452) to provide integrity and insulation (EI) fire protection from 30 minutes up to 90 minutes.

As part of the Promat SYSTEMGLAS® 360 Degree Wheel of Assurance, guidance is offered from specification through to installation, the system is designed in-house, it is fitted by a Promat approved installer and a certificate of conformity is issued on completion following an inspection by a Promat expert for maximum supply chain traceability.
