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.

Which Junctions Actually Move Your SAP Score - Our Junction-Impact Review
Not every junction is worth calculating. Before you commission anything, we rank your details by how much each one adds to the dwelling's heat loss, so you spend on the handful of junctions that move the SAP result - and leave the rest on conservative defaults.
