Homeowner information

With carbon emissions high on the global agenda and the current high cost of fuel, we are all looking for ways to make our homes more energy efficient. In addition, installing energy efficient windows is a legal requirement in order to comply with current Building Regulations.

The Thermal Rating Register rates the energy efficiency of windows and is recognised within the Building Regulations as a method to show compliance for your installation.

It uses a consumer-friendly traffic-light style A-G ratings guide similar to that used on ‘white’ goods, such as fridges, freezers, washing machines etc. This ratings label can be used by you to make more informed choices about the energy efficiency of the windows you are looking to purchase.

Each window rated by the Thermal Rating Register has a unique label, which displays the rating level, the energy rating, the window U-value, the effective heat loss due to air penetration, and the solar heat gain. Click here for an example label. (this also needs to be on the homeowner sub menu and we need a diagram with a label and “English” explanations for all the different values).

Simply put, this will help you to determine how well the window or door will perform in terms of:

• Containing and conserving heat within your house in the winter
• Keeping out the wind
• Resisting condensation
• Contributing to improved sound insulation.
