Every style of Bowaters Composite Door, whether single or double rebate, complies with the latest Building Regulations - achieving a U Value of 1.6 or less, with many styles achieving just 1.0.
Not only this, but every Bowater Composite Door is supplied with a bespoke U Value Certificate that is unique to the exact combination of door style and glazing for you to pass to your customer. A summary of the latest Building Regulations in regard to requirements for doors can be found below:
Changes to the Approved Document L of the Building Regulations in England and Wales came into force on 1st October 2010 and stipulate that doors must have a combined U value of 1.8 W/m²K - there is no equivalent to the WER rating bands for doors.
Similar changes to Section 6 of the Scottish Technical Domestic Handbook stipulate that doors must have a combined U value of 1.6 W/m²K. Just as with England and Wales there is also no equivalent to the WER rating bands for doors in Scotland.
The U Value of each & every style of Bowater Composite Door not only meets, but exceeds these standards - ensuring that a home with a Bowater Composite Door not only looks great, but is well protected from the worst of the elements.
