How We Assess Surface Condensation & Mould Risk
A guide to our standalone surface-temperature assessment — proving that a junction stays warm enough to avoid condensation and mould, when a building control body, warranty provider or insurer asks for evidence.

How We Calculate 3D Thermal Bridges
A guide to our method for the junctions a flat section can't capture — balcony connections, structural penetrations and three-way corners — and the standards behind every figure we report.

How We Calculate the P1 Junction (Party Wall to Ground Floor) in 3D
A guide to the SAP junction that can't be captured in a single section — why the party-wall-to-ground-floor junction (P1) needs two full 3D models, and how BR 497 turns them into the Ψ-value your assessment needs.
