Why Choose Flush Casement Timber Windows?

Flush casement windows are characterised by the opening sash sitting level with the surrounding frame, creating a sleek and understated appearance.

This design has been used for generations in traditional British architecture, yet remains equally suited to modern homes where clean lines and subtle detailing are valued. Combined with advanced glazing systems, engineered timber and high quality hardware, Douglas & Peters’ flush casement windows deliver the best of both worlds.

The result is a window that offers:

• Elegant flush fitting aesthetics
• Excellent thermal insulation
• Outstanding durability
• Enhanced security
• Smooth operation
• Fully bespoke sizing and design options

Our flush casement timber windows are designed to combine traditional aesthetics with exceptional modern performance.

Each window is manufactured using carefully selected timber options including Engineered Redwood, Accoya® and Red Grandis, allowing clients to choose the material best suited to their project requirements and long term expectations.

Key features include engineered timber construction for enhanced stability, an 83mm x 68mm frame section, concealed trickle vents, easy clean hinges, multi point espagnolette locking and a durable three coat factory applied paint finish. A wide selection of handles and ironmongery is also available to complement the style of each project.

All windows are double glazed as standard using Low-E glass, argon filled cavities and black warm edge spacer bars. Additional glazing options include Part Q compliant, toughened, laminated and integral duplex bar units.

Our advanced water based finishing system allows the timber to breathe naturally while providing long lasting protection. We can match virtually any RAL, British Standard, Dulux or Farrow & Ball colour, with painted, stained and dual colour finishes available.
