Since 16th CA British classic
01A British Classic

The UK’s most widely specified window

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.

07Common Questions

Timber casement windows — FAQs

What is a timber casement window? +

Schnauber's timber casement windows are hinged on the side, which means they are very easy to open and close. This style of window can open wide to provide maximum ventilation and light.

Where would I install a timber casement window? +

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.

Why would I choose timber casement windows? +

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.

What options are available for my wooden casement windows? +

A choice of engineered hardwood finishes and a fully reversible option. Available in an unlimited range of colours using the latest environmentally friendly water-resistant paint technology, inside and out — with RAL colour matching for consistency.

Are Schnauber's timber casement windows environmentally friendly? +

Yes — all our wooden windows are manufactured from responsible and sustainable sources certified by the Forest Stewardship Council (FSC).

How long will it take to install new casement windows? +

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.

How easy are casement windows to maintain? +

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.

Schnauber's top tips for casement windows +

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.

What is the difference between flush and stormproof casements? +

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.

How do I request a timber casement windows quote in my area? +
