When installing doors Building Regulations require compliance with Document L in England and Wales for the conservation of fuel and power, and Regulation J in Scotland for the limitation of heat loss/gain in any particular dwelling.
Oakeco doors that are marked with ‘2’ are suitable for new buildings and extensions. Products marked with ‘2+’ are suitable for replacement and refurbishment projects only.
U-values (W/m2K) are available for all applicable products and are only relevant when installed into the appropriate frame supplied with the doors.
It is the responsibility of the customer/fitter to ensure compliance with Document L and Regulation J and Oakeco recommends that customers refer to their Local Building Control Officer or architect prior to installation.
