We have a wide range of beautifully designed PVCu windows to complement any home, in a number of aesthetically pleasing styles and colours. Not only do they look great, they significantly improve your energy efficiency and security.

We only use premium high-quality products from the likes of Rehau and Kommerling and they all come with optional extras, from chrome handles to a choice of over 200 RAL colours, they can be customised to you and your needs.

We supply our windows with Low-E glass, which is coated insulating glass, resulting in low surface emissivity. This gives our windows a lower level of thermal transmittance compared with traditional glazing. It reduces the amount of heat loss out through your window, whilst allowing heat from the sun in.

This effect is known as solar gain and it comes from the sun free of charge, making your home automatically warmer without the need to turn up the heating.

Replacement Glass

Reduce the amount of heat lost through windows in your home by up to 75% – by installing units containing energy-efficient glass.

Providing your existing frames are still in good condition, you only need to replace the glazing to see a huge improvement on the energy efficiency of your home.

Or, if one or more of your double glazed sealed units (the individual glass units found within double glazing installations) is broken or misted up between the panes, we can supply and fit a replacement unit so you won’t have the cost of replacing the whole window.
