What is a French casement window?
French casement windows feature two side-hinged sashes that open from the centre, creating a wide, uninterrupted opening for more natural light and fresh air. Available in uPVC, aluminium and timber, they suit both modern and traditional homes. At Osborn’s, we install made to measure French casement windows across South London, Surrey and Kent.
Unobstructed Views
With no central post, you get a clear, open view straight through to the garden. It's the kind of detail that makes a room feel bigger the moment you walk in.
Improved Ventilation
Both sashes open fully to let more fresh air into your home. Ideal for bright, airy living spaces.
Energy Efficient
Available with double or triple glazing to help reduce heat loss. Keep your home comfortable throughout the year.
An Authentic Design
Choose from three durable materials to suit your home. The Residence Collection offers the authentic look of timber without the extra upkeep.
