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
