Windows
High-performance windows engineered for the British climate — secure, energy-efficient and built to last for decades.
The Frame
Casement Windows
Casement windows are the most common frame style in UK homes — and for good reason. Hinged at the side and opening outward like a small door, they offer excellent ventilation, easy operation, clear views and a tight, energy-efficient seal when closed. They suit virtually every property type, from new builds to period renovations.
Why It Matters
The British Workhorse, Modernised
Modern casement frames combine multi-chamber construction with multi-point locking, A-rated double or triple glazing and weather-tight gasket seals. The result is a window that's far stronger and warmer than the casements of twenty years ago, available in uPVC, aluminium or timber to suit your home and budget.
- Side-hung outward opening for great ventilation
- Tight gasket seals when closed for low draft
- Multi-point locking & internally beaded glazing
- Available in uPVC, aluminium and timber
- Wide range of opening configurations

Casement Windows — common questions
Standard casements have sashes that sit slightly proud of the frame when closed; flush casements sit perfectly level with the frame. Flush casements give a flatter, more traditional look — popular on period properties.
A lot — because the entire sash opens outward, you get full opening ventilation, much greater than a tilt-only or sash window can offer. They're particularly well-suited to bathrooms, kitchens and bedrooms.
Yes — modern casements use internally beaded glazing (so the glass can't be removed from outside), multi-point locking with hooks and shoot bolts, and reinforced hinges. They meet all current UK security standards.
It depends on material — uPVC casements typically last 25–30+ years, aluminium 40+ years, and engineered timber casements can last 60+ years with regular finish maintenance. All come with a 10-year guarantee.
Yes — both authentic external bars and slimline glazing-bar inserts are available, allowing you to add Georgian, cottage or period detailing to a modern casement frame.
Yes — modern building regulations require trickle ventilation in habitable rooms, so we include built-in trickle vents as standard. They allow continuous low-level ventilation without compromising security.
