A-rated casement windows tailored to homes in Cornwall
Cornwall's most popular window style is the charming casement window - and for good reason. Easy to use, remarkably energy efficient, and incredibly airy and bright, casement windows are typically installed in pairs or singly and are recognised by a practical side hinge that opens outwards.
Dedicated to delivering high-performance window installations that cater to a wide range of budgets and property styles, this is why we manufacture and install quality uPVC casement windows from the superb Selecta Systems collection. We also supply and install slimline aluminium casement windows from the attractive Allstyle Aluminium range.

Ideally suited to modern architectural developments, aluminium windows can be designed to satisfy virtually any setting - including restrictive designated areas, such as conservation areas and listed buildings. Premium aluminium casement window installations from RJM Windows benefit from:
• Lightweight, durable, slim frames - 'less frame, more glass'
• Ultra-efficient thermally broken frames as standard
• Exquisite collection of colours to choose from
• Undemanding, enduring performance (average lifespan is 45 years)
• Convenient concealed trickle vent option
• High security multi-point steel locking mechanisms & key-locking handles
• Marine grade powder coated aluminium windows are perfect for Cornish coastal homes - actively resisting corrosion, flexing & fading
• The most recyclable of all construction materials.
