Flush Casement
Our bespoke Flush Casement windows are manufactured to deliver exceptional performance, durability, and energy efficiency. Each window is manufactured using sustainably sourced, premium-grade timber at our specialist facility. Designed to suit your specific property needs, our Flush Casement windows feature advanced draught sealing, multi-point locking systems for enhanced security, and glazing units that perform almost twice as effectively as standard double glazing.
Flush Casement Timber Windows
Fully Customisable to Match Your Project Requirements
Flush Casement windows are designed so the opening sash sits level within the outer frame, creating a clean and elegant external appearance. Unlike standard lipped casement windows, flush designs offer a flatter finish that closely reflects the appearance of traditional timber windows commonly found on period and heritage properties.
Their timeless styling makes them particularly versatile, complementing everything from country cottages and Georgian properties to modern extensions and contemporary self-build projects. The simplicity of the flush finish creates refined sightlines that enhance a property's character without overpowering its architecture.
