- What thermal performance does casement windows achieve in Winslow?

- What is a casement window?
- A casement window has one or more sashes hinged on the side (side-hung) or the top (top-hung) that swing outward to open, plus optional fixed lights. It's the most common window configuration in the UK and is available in uPVC, aluminium and heritage flush-casement.
- Should the opening sash go on the left or the right?
- It's normally decided by the room layout — hinges on the wall side so the sash opens away from where people stand. We confirm handing at survey; both configurations are available.
