Energy Efficient Windows

At Lockwood Windows we are not prepared to compromise on quality, and have invested heavily to provide the most energy-efficient and secure window systems available on the market today.

Windows which are installed must be compliant with building regulations in regards to thermal loss, as all homes now need to be as energy efficient as possible.

The British Fenestration Rating Council (BFRC), in conjunction with the UK glazing industry and European partners, has designed a window rating system which provides simple and accurate information regarding the energy efficiency of a product.

The BFRC provides third party certification for the total thermal performance of windows, which are rated using the familiar A to G scale on the basis of their total energy efficiency, where A-rated is more energy efficient than G-rated.

This means that you can quickly choose the most suitable window for your needs, and government inspectors and agencies can quickly see if the window meets the legal requirements.

In order to achieve a C-rated window, or above, many companies are choosing to use a basic PVCu system, which achieves the required efficiency rating but is sadly lacking when it comes to security, with only a thermal plastic sleeve for reinforcement, or no reinforcement at all.

For this reason, we advise customers to think carefully before deciding which company to use for new or replacement windows, and would recommend that you ask some key questions before proceeding.
