Double Glazing

Long gone are the days of single pane windows as homes across the UK have double glaze windows installed to help make their homes warmer, which will instantly improve the energy rating of your home saving you money in your heating bills. Available as a crystal clear pane or with a glazed finish, or leaded glass design your windows will instantly look stylish and suited to your home.


Triple Glazing

For added benefits of window installation, triple glaze windows consist of 3 panes of glass instead of 2, which is standard for double glaze window installation, regardless of the frame material. For a home that is warm and saves money in heating bills, Triple glaze windows can dramatically increase the energy efficient ratings, add more protection to your home and provide sound insulation from external noise.

Available in various colours and glazing designs, UPVC windows with double or triple glazing can increase the warmth and security of your home.

Aluminium Windows

Aluminium Windows are lightweight and offer strength, durability whilst providing high thermal efficiency with their ultra slim lines and larger glass panes. The other benefits of Aluminium windows are that the material is unlikely to corrode or rust, which reduces the maintenance. Available in hundreds of colours, Aluminium Windows can be made with a different colour on the external part of the frame and another for the internal. With the RAL colours being powder coated on the frames the colour is guaranteed to not fade in years to come. A sustainable solution for Aluminium Windows that are suitable as casement windows, sash windows, tilt and turn windows and shaped windows such as curved or D-windows.
