Lipped Casement Windows simply have sashes that open out on special hinges that use friction to keep them open in the position you chose. Because this type of window opens out and has a rebated sash which lips over the outer-frame they offer superb protection against the wind and rain. They can be used to replicate any popular style of timber window with sashes that can open from the side or the bottom

Lipped Tilt & Turn Windows are most popular across mainland Europe allowing the biggest possible glass area. They are characterised by the fact that they open into your house. This can be useful if you have limited clearance outside and they are very easy to keep clean as even the outside of the glass can be washed easily from inside the room. Using a very clever hinge and locking arrangement you can either open the top of the sash at a fixed angle to allow gentle ventilation or you can open it from the side giving the maximum possible aperture to let in as much fresh air and light as possible. Be careful to consider your available space inside, as a big tilt & turn window can take up quite a bit of space in a small room

We will help you design the style best suited to your property, this could be simply copying the existing window on maybe something a little different. There is a separate information sheet available showing the most popular configurations if you want to see what else is available

Our windows make more of ambient heat

In winter, the energy efficient coated glass used in our windows retains warmth within the home. It’s also designed to exploit radiant heat energy from the sun. These properties result in significant fuel savings compared to a single glazed dwelling.

Above: The images show just how effective fitting energy efficient windows to your property can be. The right-hand side of the property still has the original windows – the reds and pinks show heat escaping. However, the new extension on the left is fitted with energy efficient windows, the lack of reds and pinks proving they help dramatically reduce heat loss

Choosing energy efficient windows, doors and conservatories to replace single glazed or older double glazed units saves energy from day one. In fact, replacing the windows alone could reduce your heating costs by up to 20% - perhaps worth up to £321 a year*

Clear, uncluttered sightlines ensure windows look well proportioned, elegant and attractive. Features like our low sightline Q-Lon weatherseal ensure performance and style with savings

Lowering heat loss at glass edges can cut window, external door and conservatory condensation by up to 80%. Glass units and our high performance Q-Lon gasket helps reduce noise pollution over a wider temperature range, too
