Britain’s most popular window since the 16th century — practical opening, strong security and excellent thermal performance, handcrafted to your specification.
Timber casement windows have hinged opening sections set in a wooden frame. Schnauber offers flush and stormproof designs with glazing and finishes selected for the property. Compare the frame profile, opening direction and existing sightlines, then agree the measured sizes and specification at survey before placing an order.
Schnauber bespoke casements combine traditional British styling with modern manufacturing technology. Precision-engineered timber, high-performance glazing — double, triple or vacuum glass — and carefully selected hardware deliver durability, smooth operation and improved energy efficiency.
The window sash presses against the frame on closing to create an airtight seal — minimising air infiltration and making casements one of the most energy-efficient styles available.

Casement windows are probably the most popular style for our residential customers — they suit any type of property and come in many designs. They're perfect for kitchens and bathrooms, where condensation typically occurs, as they provide good levels of ventilation.
For a traditional British aesthetic, or if your home is in a conservation area which typically requires timber windows. They're also highly energy efficient: the sash presses against the frame on closing to create an airtight seal, minimising air infiltration.

Yes — all our wooden windows are manufactured from responsible and sustainable sources certified by the Forest Stewardship Council (FSC).
In a typical 3–4 bedroom home with windows replaced upstairs and downstairs, around 5–10 days — depending on rendering, bay windows and window sizes.
One of the easiest window types to clean as they open fully — and when designed to comply with Building Regulations Part N they can be cleaned entirely from inside. Pre-treated with non-toxic preservative, maintenance is only needed every 5–10 years.
If you have young children, we recommend additional safety fittings. Casement windows should not be too large or too heavy, as the opening has to support the window.
A flush casement closes in line with the outer frame; a stormproof design overlaps it. Compare samples and frame sections with the appearance of your property, and discuss exposure and glazing requirements when agreeing the specification.
