U-Value is the measurement of thermal transmittance through a material or through the build-up of multiple materials known as an element. JPA Designer U-Value Calculator calculates the thermal transmittance of building elements in order to predict the rate of conduction heat loss through the element. The resulting U-values are used in SAP calculations and also for compliance with Building Regulations.
JPA Designer U-Value makes calculations straight-forward, with construction elements built-up layer by layer; a process made easier by the comprehensive database of generic and branded materials. The U-Value calculator also includes a ‘variable layer’ feature which makes it easy to compare the effect of design changes on the thermal performance.
Calculate U-Values for:
- Walls, roofs and floors (ISO 6946 ‘combined method’);
- Lightweight steel framed elements (BRE Digest 465 method);
- Ground floors and basements (ISO 13770 method).
- Printing your U-Value calculations for your clients using PDF.
- Use in SAP calculations.
