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 Industry and are involved in on site installation of Fire Resistant Glazing into timber screens and doors
Performance criteria
You must be able to:
- comply with health and safety requirements and procedures at all times
- follow assembly and installation guidelines and instructions to meet specifications
- install systems that take account of bead types following standard operating procedures
- apply timber treatments to meet specifications following standard operating procedures
- obtain and refer to test, assessment and approval reports relevant to systems being installed
provide components to meet specifications
check completed installations meet specifications
Knowledge and Understanding
You need to know and understand:
- how timber behaves in fire
- special requirements that apply for framed systems and doors
- why type and species of timber is important
- the importance of timber section thicknesses
- the importance of installing systems of matched named components, including doors, all hardware and edge and frame smoke seals
- function of timber beads and bead fixings
- which bead fixings to use and how to fit them
- glazing guidelines for fire-resistant glass, especially seal type and edge cover
- requirements for glazing setting blocks and their function
- attention to glass edge cover specification
- requirements for impact rating of glass according to application
- importance of not extending glazing apertures beyond approved sizes
- importance of following glazing configurations and layouts provided
- main factors that determine fire-resistance performance of fire resistant glazing in timber systems
- special requirement of proprietary systems that achieve fire resistance classifications longer than 30 minutes
- why provision for glazing expansion is important
- importance of bead profile and types of timber for beads
- types of treatments used on beads
- risks of using surface treatments that are not approved
- importance of not exchanging named components for non-specified components without manufacturer's approval
- why minimum edge cover limits are important
- handling and glazing of double glazed units
- checks made on systems following installations and how to make them
- implications of making any changes to components within systems
- how to confirm certified glass, seals and framing systems
- requirements for sealing around installed systems and surrounding structures with approved fire stopping materials
- importance of not modifying a factory-delivered door on site
- importance of not damaging provided smoke and fire seals
- importance of not cutting glazing openings in doors that are not designed for glazing
