Who This is For Strata Managers Building & Asset Managers Builders & Developers Facilities Managers If your building includes large-scale glazing, exposed corners or recurring condensation or leaks, this checklist is designed to support a structured review of system performance and condition. Have You Noticed Any of These? If any of the following look familiar in your building, the sections below can help you identify where the concern may originate. A Clearer Picture Starts Here. How To Use This Checklist Work through each section and consider whether the following items appear consistent with expected glazing performance and maintenance practices. YESappears consistent UNSUREmay require further review NOpotential concern identified 0 YES 0 UNSURE 0 NO 41 NOT YET SET 1 Design and Compliance Considerations The glazing system appears to have been considered in relation to: AS 2047 AS 1288 NCC 2022 Amendment 2 Documentation and engineering checks: Documentation is available relating to tested system performance Wind loads appear to have been determined using the appropriate standard (AS 4055 for housing, or AS/NZS 1170.2 for commercial or taller buildings) Design pressures appear generally consistent with the installed glazing system’s tested performance ratings Insight: Where documentation is unavailable or incomplete, it may be difficult to assess whether systems align with relevant performance expectations or compliance requirements. 2 Installation and System Configuration The glazing system appears generally consistent with tested or specified configurations No obvious unauthorised modifications to framing, seals, or glass thickness are visible Mullion spans and fixings appear generally consistent with available specifications No apparent substitution of key glazing components or materials is evident Insight: Variations between installed systems and tested configurations may influence long-term system performance. 3 Structural Performance Considerations Mullion deflection appears generally consistent with expected Serviceability Limit State (SLS) performance The glazing system appears to have been considered for Ultimate Limit State (ULS) wind loading conditions No visible indications of: Frame movement Bowing mullions Stress cracking Insight: Movement or deformation may contribute to water ingress or other longer-term performance concerns over time. 4 Water Penetration and Sealing Documentation or evidence relating to water penetration resistance testing is available Seals appear intact, continuous and appropriately installed No visible indications of: Water staining around frames, sills, or surrounding walls and ceilings Surface deterioration: peeling, bubbling, or chipping paint or wallpaper Structural changes: swollen or warped frames, sagging plasterboard, loose tiles, or lifting floorboards Internal dampness, drafts, or localised temperature inconsistencies Condensation or fogging between glazing panes Mould or mildew near glazing systems Sealant deterioration or separation Difficulty operating windows or glazed doors Insight: Water ingress pathways are not always visible at the source and may originate from surrounding or concealed areas. Further investigation methods, such as AAMA 501.2 water testing, may assist in identifying potential water pathways where appropriate. 5 Glass and Edge Support Conditions The glazing type appears generally suitable for its application in the context of AS 1288 Glass edges appear adequately supported and protected No visible indications of: Edge chipping Stress fractures Incorrect glazing packers Edge delamination Glass deformation General glass defects Insight: Localised defects or inadequate edge support may affect glazing performance over time. 6 Exposure and Higher-Risk Areas Corner glazing areas appear to have been considered in the overall design and installation High wind exposure areas appear to have been reviewed Large uninterrupted glazing panels appear to have been assessed in relation to their exposure conditions Higher-risk areas appear to have been engineered and reviewed following installation Insight: Corners, exposed elevations and large glazing panels are typically subject to increased wind and structural stresses, and may warrant closer review over time. 7 Maintenance and Inspection Records A documented inspection or maintenance schedule is available Periodic inspections or facade reviews appear to have been undertaken Maintenance activities appear to be recorded and tracked Previously identified leaks or glazing concerns appear to have been investigated and addressed Insight: Ongoing inspection and maintenance records may assist in supporting long-term performance management and insurance-related processes. Your Details Performance Profile Mostly Yes: Conditions appear generally consistent with expected system performance, with ongoing monitoring recommended. Mix of Yes and Unsure: Some areas may benefit from further review or investigation. Multiple No: A more detailed assessment may assist in understanding potential performance concerns. Consider contacting a specialist for a structured assessment of your glazing system. Performance Depends on More Than Design Glazing systems are designed to perform under specific conditions. Where those conditions are not fully achieved through design, installation, environmental exposure, or ongoing maintenance, system performance may gradually change over time. Early identification through structured review may assist in addressing issues before they affect durability, performance, or broader building condition outcomes. Understanding Your Building’s Performance A structured assessment can help provide greater clarity on how glazing systems are performing and where additional attention may be beneficial. WS Remedial Group works with building owners and managers to support the long-term performance of glazing systems through: Facade and glazing inspections and reviews Compliance-focused assessments Leak diagnosis and investigation Targeted remedial works and maintenance support If you would like a clearer understanding of your building’s glazing condition and performance and learn more about specialist glazing led by people who've done this for decades, we are here to assist.
