U-values must be independently certified


Dear Ian

A few people are waking up to the implications that the latest Building Regulations have for doors. It’s down to individual companies to prove their door complies with a U-Value of at least 1.8W/m2K. The legislation comes into force on 1st October.

PVC panel doors, and timber and aluminium doors may struggle to comply, but the problem for most companies will be the proof – which councils are asking for already.

It won’t be acceptable to have generic U-Values for certain styles, or - worse still - to have a standard rating that ‘applies to all doors’. It won’t be enough for companies to say they’ve worked it out themselves if they don’t have the test data to prove it.

Some people say it can’t be done. But we believe meeting the new legislation isn’t just achievable; it’s also possible to offer a tailored U-value for each and every door configuration that is independently certified.

This is what Door-Stop is working towards, with various independent authorities and testing houses to offer this accreditation credibly. Our information will not be generic. The web is full of people offering generalisations without credible proof – we don’t plan to be one of them!

Yours sincerely

Nick Dutton
Managing Director
