THERMAL BRIDGING

Thermal bridging occurs where heat can travel more easily through the building fabric — typically at junctions such as wall‑to‑floor connections, around windows and doors, or where structural elements interrupt insulation. These areas create “weak spots” that increase heat loss and can lead to condensation or mould if not properly detailed.

By using correct junction details or modelling bespoke ones, we reduce these losses and improve the overall energy performance of the dwelling.

Where possible, we use existing thermal‑bridging details from industry standards or manufacturers. These provide reliable, pre‑modelled values that can be used directly in your SAP calculations.

For bespoke or non‑standard construction, we can model each thermal‑bridge junction to produce accurate ψ‑values. This is done using AutoPSI software and ensures your SAP assessment reflects the actual design rather than generic assumptions.
