It is our aim to provide customers with the most advanced technical information in the industry and we are pleased to announce the launch of our new online Psi-value calculator.

The Keystone Group is the first lintel manufacturer to offer a Psi value calculator designed for energy assessors and architects who calculate thermal bridging and value engineer specifications to meet regulations and code of sustainable home requirements.

The Key benefit of the Psi value calculator is that you can obtain a psi value with a few clicks of a button – FREE OF CHARGE. Generally this thermal bridging information takes a specialist company a few days to turn around with typical costs between £200 and £400 per construction detail. As the new building regulations put more emphasis on reducing heat loss within buildings, the focus is on thermal bridging. Energy Assessors can now obtain a lintel Psi value from our online calculator and directly input the lintel psi value into their SAP calculations and view the performance benefit. Specifically calculated Psi values will help lower the y value within the sap calculation assisting Part L compliance. Psi value calculations couldn’t be simpler, by a click of a button you can have a Psi Value Certificate emailed to you.

To ensure accuracy, all Psi-values calculations have been generated by trained thermal modellers using Physical Trisco software which is also by BRE.

If you have any additional queries or problems with working out your Psi-value then please give the Technical Services team a call on 01283 200 150.
