Most of our surveys end in one of two ranges: sash or casement. Neither is better. They suit different houses and different rooms, and plenty of homes use both.
What a sash window gives you
A box sash slides vertically, so it never swings into the room or catches the wind. Open it top and bottom and warm air leaves through the upper gap while cooler air enters below, ventilation the Victorians designed on purpose. On Georgian and Victorian facades a sash is usually the original language of the house. We build traditional box sash and Yorkshire-style sliding sash with authentic detailing and smooth modern operation.
What a casement gives you
Casements are side-hung and swing outward, sealing tighter as the wind pushes against them. They come in flush styles, sitting level with the frame for a clean modern face, and stormproof styles with an overlapping edge. Casements are also the range we fit most when replacing ill-fitting uPVC, because the style suits almost every property built in the last century.
Room by room
Kitchens and bathrooms love casements: one hand opens them wide for quick ventilation. Bedrooms on the street side often suit sash, which never protrudes over a pavement. For upper floors that need easy cleaning from inside, look at our tilt and turn range, which swings fully inward.
Either way, the spec is yours
Hardwood or treated softwood, any colour and finish, and double, triple, Slimlite or vacuum glazing. Every window is made to measure, so the choice is about style and use, never about compromise.
