Fabric & thermal detail
PSI thermal bridge calculations
Give the junctions between building elements the attention they deserve.
What this service helps you do.
Heat loss occurs at junctions as well as through walls, roofs and floors. Ordellis reviews the agreed construction details and calculates PSI values to support the project’s thermal bridging strategy and energy assessment.
What’s included.
- Review of the junction drawings included in the agreed scope.
- Thermal modelling and PSI-value calculation for agreed details.
- A report documenting the geometry, materials and calculation assumptions.
- Coordination of the results with the dwelling’s energy assessment.
What we need to get started.
- Dimensioned junction details with continuous insulation shown.
- Material thermal properties and product information.
- Relevant wall, floor, roof, window and door build-ups.
- The junction schedule and agreed measurement conventions.
A calculated PSI value applies to the detail assessed. Revised geometry, materials or insulation continuity should be checked before reusing the result.
Your questions, answered.
Which junctions should be included?
Send the junction schedule or construction details. The quotation will identify the relevant wall, floor, roof, opening and other junctions to assess.
Can these results support SAP calculations?
Yes, when the assessed details and measurement conventions match the dwelling specification and the relevant assessment requirements.
