Using our experience in Passive House and all we have learned in 15 years we can now proudly announce the first of what will be many Psi Value Packages

​

A host calculations, diagrams of the construction, materials used, the arrangement, psi, chi and fRsi.

​

These have been created based on the experience of built Passive and NZEB houses with the shared expertise of contractors and designers.

​

We will constantly expand this library but have the first 25 details as a prototype starting with external insulation, timber frame and external insulation retrofit.

​

The Psi values that will be listed can be used for Passive House & Building Regulation applications. It is our aim to take the sting out of thermal bridging for all designers and contractors and so the 25 most common details were calculated to both standards.

​

If you would like to learn more about thermal bridging please see the thermal bridge section of this website or the course signup page for details on how you too can learn to calculate them in house.
