GQAFEN25 Use of fire-resistant glazing in timber screens and doors

Overview

This standard is concerned with the use of fire-resistant glazing in timber screens and doors. You will understand the factors that influence the behaviour of timber on exposure to fire and how each of the component parts of a fire-resistant timber system interact to provide the required levels of fire-resistance of a timber system.

This standard is for you if you work in the Fenestration and Glazing Industry and are involved in on-site installation of fire-resistant glazing into timber screens and doors

Performance criteria

You must be able to:

1. comply with health and safety requirements and procedures at all times
2. follow assembly and installation guidelines and instructions to meet specifications
3. install systems that take account of bead types following standard operating procedures (SOPs)
4. apply timber treatments to meet specifications following SOPs
5. obtain and refer to test, assessment and approval reports relevant to systems being installed
6. provide components to meet specifications
7. check completed installations meet specifications

Knowledge and understanding

You need to know and understand:

1. how timber behaves in fire
2. special requirements that apply for framed systems and doors
3. why type and species of timber is important
4. importance of timber section thicknesses
5. importance of installing systems of matched named components, including doors, all hardware and edge and frame smoke seals
6. function of timber beads and bead fixings
7. which bead fixings to use and how to fit them in line with SOPs and specifications
8. glazing guidelines for fire-resistant glass especially seal type and edge cover
9. requirements for glazing setting blocks and their function
10. attention to glass edge cover specification
11. requirements for impact rating of glass according to application
12. importance of not extending glazing apertures beyond approved sizes
13. importance of following glazing configurations and layouts provided
14. main factors that determine fire-resistance performance of fire-resistant glazing in timber systems
15. special requirement of proprietary systems that achieve fire-resistance classifications longer than 30 minutes
16. why provision for glazing expansion is important
17. importance of bead profile and types of timber for beads
18. types of treatments used on beads
19. risks of using surface treatments that are not approved
20. importance of not exchanging named components for non-specified components without manufacturer's approval
21. why minimum edge cover limits are important
22. handling and glazing of double glazed units
23. checks made on systems following installations and how to make them in line with SOPs
24. implications of making any changes to components within systems
25. how to confirm certified glass, seals and framing systems
26. requirements for sealing around installed systems and surrounding structures with approved fire stopping materials
27. importance of not modifying a factory-delivered door on site
28. importance of not damaging provided smoke and fire seals
29. importance of not cutting glazing openings in doors that are not designed for glazing
30. how to recognise certified door sets and interpret certification labelling
31. additional requirements for glazed systems in 60 minute rated doors compared with 30 minute doors
