Building Envelope & Heat Loss

Thermal bridging, insulation voids and air leakage on facades and elevations, reported on a balance-of-probability basis with every finding cross-referenced against RGB.

THERMAL + RGB

What we check for

  • Thermal bridging at structural junctions — balconies, parapets, lintels
  • Insulation voids and gaps in cavity or external wall insulation
  • Air leakage patterns around window, door and service penetrations
  • Cold bridging at render/cladding transitions
  • Visible cladding or render defects that could explain a thermal signature (RGB)
  • General elevation condition and weathering

An example of what you get back

Every finding in every report follows the same structure — location, frame reference, affected area, confidence, probable cause and recommended action, rated Red / Amber / Green. Here's a worked (illustrative) example from this survey type.

Finding 1: First-Floor Balcony Threshold — Cold Bridging

LocationSouth elevation, first-floor balcony threshold, units 4–6
Frame reference0012_T / 0012_RGB
Estimated affected areaApprox. 6 linear metres along the threshold
ConfidenceModerate
Severity rating (RAG)AMBER

Observation: A cool linear thermal signature runs along the balcony threshold, consistent across two passes at different times of day, distinct from the surrounding wall temperature.

Probable cause: On balance of probability, consistent with a structural cold bridge at the balcony-to-floor slab junction, where continuous insulation has likely been interrupted.

Recommended action: Recommend a fabric specialist review the junction detail; consider remedial insulation at next planned works.

How the RAG rating works

Every finding on every survey type is rated against the same published definitions, so a Red on one job means the same thing as a Red on the next.

● RedA live risk of water ingress, structural risk, or a safety hazard — flagged for prompt action.
● AmberLikely to progress to failure if left unaddressed, but not currently causing a problem.
● GreenCosmetic or early-stage — worth recording, not urgent.
