Building-Envelope Inspection and Testing

Building envelope problems rarely come from one bad product. They come from interfaces: window-to-wall junctions, roof edges, penetrations, movement joints and transitions between trades. Design details are often incomplete, submittals are approved without checking continuity of the air and water barriers, mock-ups are skipped to save time, and field tests are specified but carried out too late, on the wrong areas, or without clear pass criteria. In hot and humid climates, high temperature differences and dust add to the problem, and defects appear as leaks, mould, high cooling loads and damaged finishes.

This programme follows the envelope through the project life cycle. It moves through five stages: understanding how the envelope controls water, air, heat and vapour; reviewing design and submittals for continuity; inspecting installation and mock-ups; planning, witnessing and interpreting field tests; and diagnosing defects in existing buildings and closing them out.

Built on recognised practice. The programme references widely used standards and guidance, including ASTM E2813 and ASTM E2947 on building enclosure commissioning, ASTM E779 and ISO 9972 for whole-building air leakage testing, ASTM E1186 for air leakage site detection, ASTM E783 and ASTM E1105 for field air and water testing of windows and curtain walls, the AAMA 501.2 field water hose test, and ASTM C1060 for infrared inspection of envelope insulation. Participants learn how to specify and apply them on site, not only what they say.

Decisions this programme improves. Which envelope details need a mock-up or a performance test; when and where to sample installed work for field testing; how to set clear pass and fail criteria in the specification; whether a failed test indicates a local defect or a systemic problem; what remedial work and retesting to require; and which evidence to keep for handover and warranty.

How it is delivered. Twenty hours across five sessions, built around one running case: a mid-rise building with curtain wall, punched windows and a flat roof, followed from design review through mock-up testing and field inspection to a leak investigation after handover. Participants review details, prepare an inspection and test plan, interpret test reports and thermal images, and write a defect close-out report.

In-house option. For organisations, the programme can be tailored to your own specifications, envelope systems, inspection and test plans and climate conditions, and delivered to design, construction, quality and facility management teams together so that everyone applies the same acceptance criteria.

Who Should Attend

Objectives

Explain how the envelope controls water, air, heat and vapour, and identify the control layers in a given wall or roof detail

Review drawings and submittals for continuity of air and water barriers at interfaces and penetrations

Prepare an envelope inspection and test plan with hold points, sampling rules and pass and fail criteria

Inspect installation of cladding, fenestration, membranes, sealants and roofing against specifications and manufacturer requirements

Plan and witness field water penetration and air leakage tests on windows and curtain walls

Interpret results from whole-building air leakage tests and relate them to specification targets

Use infrared thermography and smoke tracing to locate air leakage and thermal defects

Diagnose the cause of leaks, condensation and sealant failures in existing buildings

Specify remedial work, retesting and documentation to close out envelope defects

Compile envelope records for handover, warranties and future maintenance
