What is important when specifying and installingFire-resistant Glazing Systems?
• The framing system
• Timber
• Steel
• Aluminium
• The glass
• The glazing components/compounds
• Fire test or assessment evidence
• Quality of installation

Understanding Fire-ResistantGlazing Systems
Potential issues with Framing Systems
• In particular, with timber framingsystems, the framing may bemanufactured and installed by differentcontractors to the glazing contractor. Theglazier must confirm:
• The framing has been manufactured inaccordance with the fire test or assessmentspecification
• It is installed into the building fabric correctly

Understanding Fire-ResistantGlazing Systems
The Framing System
• Timber framing – critical factors
• Species and density of timber used
• Section sizes and profile
• Rebate upstand size
• Glazing bead profile, in particular:
• Square edge top face or
• Chamfered or beveled top face
• Bead fixing details

Understanding Fire-ResistantGlazing Systems
The Framing System
• Steel and aluminium frame systems
• Generally supplied and fitted by a singlecompany or contractor
• Critical to ensure it is installed into thebuilding fabric correctly

The Fire-Resistant Glass
• Performance of Fire-Resistant Glass
• When tested for Fire-Resistance, glass will becatagorised for use in the UK as:
• Exx (e.g. E30) – Integrity only glass, thenumber indicating the period it willprovide protection
• EIxx (e.g. EI60) – Integrity and insulationglass, the number indicting the period itwill provide protection
• EWxx (e.g. EW60) – Not recognized in UK

The Fire-resistant Glass
• Marking of Fire-resistant Glass
• Glass to be used in fire-resistant systemsshould be permanently marked with thefollowing in a visible location:
• Manufacturers name, trading name or producttradename
• Product standard e.g. BS EN 12150, BS EN 14449etc.
• Safety classification if appropriate
• Fire-resistance e.g. E30, EI60 etc.

Glazing components and compounds
• The glazing components and compoundsmust be as stated in the test orassessment evidence:
• Substitution without supporting evidence isnot allowed
www.ggf.org.uk
Understanding Fire-ResistantGlazing Systems
Quality of Installation
• Provided the framing material, glass andglazing components/compounds are asspecified in the test or assessmentevidence, the performance of the Fire-resistant Glazed System is reliant on:
• The correct installation of the frame into thebuilding fabric and
• The fire-resistant glass being installed in theframe correctly using the materials specified
www.ggf.org.uk
Understanding Fire-ResistantGlazing Systems
Quality of Installation
• The installation is as critical as thecomponent parts of a barrier to fire
• The GGF has developed installer trainingbased on 2 GGF documents:
A Best Practice Guide in theSpecification and Use of Fire-Resistant
Glazed Systems
• Referenced in Approved Document B

Quality of Installation
• The GGF installer training workshop:
• Knowledge based workshop
• Knowledge assessment at end of course
• Initial courses in Northern Ireland
• Will be rolled out in England, Scotland andWales during 2014
• Delegates received a certificate to showattainment
• Intend to move to a registered list and issue anapproved installer card

What is the result if the wrong system, glassor components are used?
What happens if the quality of installation isnot ‘up-to-standard’?
