Psi-value Calculations when
using Superglass Insulation

To help specifiers achieve Part L, the new Superglass Psi-value Guide features a range of common junctions for external masonry cavity walls and masonry party walls using Superglass insulation. Simply email us the reference number of the junction you need and we will send you the calculations.

We have also introduced an advanced on line calculation tool, where you can instantly download common calculations using 125mm & 150mm Superwall 32.

These Psi-values were calculated by our in-house Technical Services Team, who are all members of the Elmhurst Energy Psi-value Competency Scheme. If you require bespoke calculations please contact the team on technical.stirling@etexgroup.com
