Emissivity measured by National Physical Laboratory.
Thermal resistance measured by
Independent Test Laboratories.
Tested to BS EN 12153:2000 for water tightness
and air permeability.
Manufactured in the UK and meeting the requirements
of
BS EN ISO 9002.
Condensation Risk
Further to calculating the thermal insulation requirements through a cavity wall,
a check should be made for predicting the risk of condensation within the structure.
This should be
carried out using the method described in BS5250:1999.
