Thermal Analysis

Thermal analysis of our windows and doors can be done by several means, the design team uses “LBNL software THERM” if required to produce a heat flow through a section and “LBNL software WINDOW” if a bespoke thermal calcualtion is required.

JPF also utilzes the latest software from the extrusion sources and can give average weighted U-Values for a contract as well as whole window U-Values and Centre Pane U-Values.

Infared images can be used to determine heat loss in a facade as well as the areas which are insulated.
