Energy Assessors
Technical guidance and performance data to support accurate SAP calculations and confident specification.
Technical support for energy assessment
Our technical team can provide guidance on lintel selection, thermal bridging and product performance, helping Energy Assessors identify appropriate solutions for different construction details and project requirements.
With specialist knowledge of lintel design and thermal performance, we can support projects from the early stages of assessment through to final specification, helping to make the process of evaluating lintel performance as straightforward as possible.
Supporting compliance with reliable thermal data
Our PSI Value Calculator also makes it easy to explore the thermal performance of different lintel solutions and construction details, providing calculated PSI values to support assessment and specification.
Where a standard construction detail or existing PSI value does not meet the requirements of a project, our technical team can carry out bespoke PSI value calculations. This provides project-specific thermal performance data for more complex or individual construction details.
By combining an extensive library of PSI values with online calculation tools, bespoke calculations and specialist technical support, Keystone Lintels can help Energy Assessors accurately assess thermal bridging and provide the information required to demonstrate compliance with current Building Regulations.
"The online PSI Calculator is an excellent tool during the early design stages, while the verified PSI values and thermal data enable accurate and compliant SAP assessments."
