Below is a selection of U-Value calculations for different thicknesses of Sips Eco Panels used in a roof and wall constructions. NB - because the SIP panel provides the bulk of the insulation, altering the roofing finish does not drastically affect the U-Value. All dimensions are nominal and within a tolerance of +/-3mm
Internal & External OSB Thickness; (mm)
Foam Core Thickness: (mm)
U-Value as Wall Type 1: (W/m2)
U-Value as Wall Type 2: (W/m2)
U-Value as Wall Type 3: (W/m2).
U-Value as Roof Type 1: (W/m2).
U-Value as Roof Type 2: (W/m2)
