You will receive your TRR labels once you have had an audit for our auditor.

We aim to complete audits within 8 to 10 weeks after all the required information has been received.

The Master label provides a single label reference number fixed to each window manufactured. Once you have received your A/B/C labels, your Master label acts as an umbrella label to cover all of your other labels.

Initially this acts as a label to show you are Compliant with the Building Regulations, before you receive your A/B/C labels.

All members, with the exception of timber installers and/or manufacturers, will receive a Master label.

The Master label reference number and Thermal Rating Register website address must be included on the Permanent label. You may also optionally add your company information.

The Master label must be a minimum size of 65 x 15mm, must be stuck on with high tack glue so there is a permanent adhesion, both the label and ink must be waterproof, the text must be 10 point bold, and the label must be fixed to an opening light. Full details are available in the relevant quality management system manual.

The Master label should be put on the opening sash of the frame, or alternatively, printed on the spacer bar.
