Supporting SAP Assessors with proven performance

At GDeck, we understand the critical role SAP Assessors play in demonstrating compliance with Building Regulations and delivering accurate energy performance assessments.

That’s why we provide the technical detail, Psi calculations and drawings you need, making it easier to model junctions and verify U-value performance.

Detailed Psi Calculations

Precise Psi values calculate junction heat losses between the floor and wall.

GDeck offers an extensive library of pre-modelled junctions
Floor and wall junctions are modelled in both parallel and
perpendicular directions.
Where new details are required, our in-house technical team can quickly provide calculations.

This means you can be confident in accurate modelling of overall heat losses for any dwelling design.
