This U-value calculation is provided to customers free of charge and is based on information you have entered. No duty of care is owed to the recipient or any other third party and British Gypsum cannot accept liability in respect of the information shown. The specification should therefore be approved by the project design and management authority before use to ensure that it meets with their specific project requirements. This calculation must be read in conjunction with current literature at british-gypsum.com or isover.co.uk. British Gypsum/Isover products must be installed in accordance with current literature and relevant standards. The properties and suitability of any non British Gypsum/Isover products must be verified with the relevant manufacturer prior to installation. Any bonded wall lining system identified assumes background suitability - where any uncertainty exists an alternative mechanically fixed lining system should be considered. All wall lining solutions to masonry backgrounds assume that the background is dry and completely weather tight.
If the type of construction you have is not included within this database, please send your enquiry, describing the precise make-up, u-value requirement, site address and contact details, to email@example.com.
