TempaSoak™ Heat-Soaked Toughened Safety Glass is suitable for residential, commercial and architectural applications where a reduced risk of spontaneous toughened glass breakage is required.

Typical applications include:

• Building façades
• Structural glass walls
• Balustrades and barriers
• Glass canopies
• Overhead and sloped glazing
• Point-fixed glazing
• Frameless entrance glazing
• Shopfronts
• Glass fins
• Large or difficult to replace panels
• High level glazing
• Toughened laminated safety glass assemblies

Heat soak testing should be considered where glass breakage could present a risk to people below, compromise a barrier, require difficult access or cause significant operational disruption.

• Heat soaking reduces but does not eliminate the possibility of spontaneous toughened glass breakage.
• Heat soaking does not prevent breakage caused by impact, edge damage, excessive loads, thermal stress, incorrect installation or building movement.
• Heat-soaked monolithic toughened glass does not remain intact after breakage.
• Applications requiring post-breakage retention may require a laminated or toughened laminated glass configuration.
• Glass thickness, dimensions and make-up must be selected for the applicable loads and support conditions.
• All cutting, drilling, notching and edge processing must be completed before toughening and heat soak testing.
• Heat soaking must be specified before manufacture and cannot be completed after the glass has been installed.
• The glass must be installed in accordance with Metro’s requirements, the relevant system documentation and the current New Zealand Building Code.

When correctly selected, designed, manufactured and installed, TempaSoak™ Heat Soaked Toughened Safety Glass complies with or can contribute to compliance with relevant provisions of the New Zealand Building Code, including:

• B1 Structure
• B2 Durability
• E2 External Moisture, as part of a complete external glazing system
• F2 Hazardous Building Materials
• F4 Safety from Falling, where incorporated into a specifically designed and compliant barrier system
• G7 Natural Light

Heat soaking is an additional quality-assurance process and does not replace the need to select and design the glazing in accordance with the applicable requirements of NZS 4223 and AS/NZS 2208.

• Reduced risk of nickel sulphide related spontaneous breakage
• Increased mechanical and thermal strength associated with toughened safety glass
• Breaks into relatively small particles if fractured
• Can be laminated where post breakage retention is required
• Suitable for applications where access and replacement would be difficult
• Safety glass manufacture is undertaken in accordance with AS/NZS 2208
• Final performance depends on the glass thickness, panel size, fixing method, support conditions and project-specific loads
• Heat-soak certification or production records should be retained where required by the project documentation

Warranty & Maintenance

• 10 year double glazing warranty
• Heat soaking reduces but does not warrant the complete elimination of spontaneous breakage.
• Refer to the attached Metro Performance Glass warranty document for coverage, exclusions and claim requirements.
• Maintain in accordance with the attached Metro Performance Glass care and maintenance guide.
• Regularly inspect exposed edges, holes, notches, fixings and support systems.
• Do not cut, drill, notch or modify the glass after manufacture.
• Impact damage, scratching, edge damage, incorrect installation and excessive building movement may invalidate warranty coverage.
