Choose your perfect window style
Craft your ideal bay window configuration using our range of sliding sash windows for authentic period charm, lipped casement windows for traditional character, or flush casement designs for contemporary appeal. Customise your windows further with our options:
- Create traditional styles such as horizontal, cottage, Georgian, or marginal bar using our applied 16mm, 25mm and 35mm glazing bars
- Make a statement using lead in traditional designs such as diamond, square and Queen Anne style
- Choose from our paint and stain options to complement or contrast with your home.
Redwood or hardwood timber windows
All our products are manufactured using certified sustainably sourced engineered laminated timber. We offer both redwood (Scots Pine) and hardwood (Dark Red Meranti) – both with the same extensive warranty. When comparing the two, our hardwood has a more of an open grain structure meaning it gives more of a textured finish, particularly when stained.

Looking for bay windows for your conservation area home? Our Heritage profile timber bay windows are designed for Conservation areas and listed buildings, offering both single glazing and slimline double glazing configurations.
The 16mm slimline double glazing units feature internal glazing with drainage and ventilation systems, delivering U-values of 1.3W/m²K whilst remaining fully compliant with current building regulations.

SustainabilityBay Window FAQ's
How long do timber bay windows last?
Our timber bay windows are engineered for a 60+ year lifespan with minimal maintenance. We use premium sustainably sourced timber and precision manufacturing techniques, backed by a 10-year warranty for complete peace of mind.

Can I mix different window styles within one bay window?
Yes, our bespoke manufacturing allows you to combine sliding sash, lipped casement, flush casement, and fixed panels within one bay configuration to achieve the perfect balance of ventilation, light, and architectural detail for your needs.
Are timber bay windows secure?
Yes, all our timber bay windows include high-quality multi-point locking systems and can be fitted with laminated security glazing if required. The robust timber construction and premium ironmongery provide excellent security for your home.
What glazing options are available?
We offer double and triple glazing options, acoustic glazing for noise reduction (up to 42dB with our Ambient range), and various glass types including low-emissivity coatings, self-cleaning glass, and decorative options to suit your specific requirements.
