Tilt and Turn


These dual-purpose windows can be tilted and opened in various ways to ensure secure ventilation. A quarter turn of the handle will open the top of the window, allowing it to tilt inwards from the bottom hinges. Another quarter turn in the same direction will allow you to open the window fully in towards the property, allowing you to clean the window in a safe manner.

Sash Windows


uPVC sash windows retain the distinctive charms of the traditional sash design whilst avoiding any potential problems which may occur from daily use – so no sticking, no rattling and no weights and sash cords. Instead you get a smooth gliding action, plus inward tilting for easy cleaning.


Warm Edge Spacer bar

1What is a Warm Edge Spacer bar?
A Warm Edge Spacer bar is a product that is made from an insulating plastic composite material that is thermally optimised to prevent heat lose through the edge of the double or triple glazed unit.

Argon gas filled unit

1What is the benefit of Argon filled units?
The benefit of substituting dehydrated air with an inert gas, such as argon, is that you can further increase the energy efficiency of your double glazed units. Argon, which has 34% lower thermal conductivity than air, is the most commonly use.
