Lipped Casements - Casement windows are single or double-panelled windows, hinged from the side, top or bottom. Operated with a handle, panels open outward and close proud of their frame. They are our most popular window for their ease of use and availability in different styles, colours & finishes.

Flush Casements - Flush casement windows open from top or side hung hinges, closing so that the face of the window sits flush with the frame. By comparison traditional casement windows have a lip that sits over the window frame when closed.

Secondary glazing provides a potential solution for improving the energy efficiency of single glazed windows i your home. Installing secondary glazing sees the existing windows left in place and another pane of glass installed inside to form something approximating double glazing.

Secondary Glazing is also a great way to improve acoustic performance of your windows. Often used on properties above busy roads and high streets as a cheaper alternative to double glazing.

Also used in listed building and conservation areas where building restrictions limit the changes that can be made externally to your windows.

Treble glazing - Triple-glazed windows have three panes of glass, one more than double-glazed. The space between the glass is filled with an extra layer of insulating inert gas, like argon. Together with the third pane of glass, triple glazing often has a higher energy rating than double glazing. It helps to keep your home warmer, quieter and safer.
