Why Homeowners Choose Aluminium Casement Windows
Aluminium casement windows give you the flexibility to modernise appearance without sacrificing practical performance, making them a reliable fit for both refurbishment and new-build projects.
Thermally Broken Frame Engineering
Modern aluminium casement systems use thermal break technology to reduce heat transfer through the frame and support better year-round comfort.
Durable Long-Term Performance
Aluminium is low maintenance and weather resistant, making it a practical option for homeowners who want crisp design and dependable everyday operation.
System and Configuration Options
We help you match sash style, frame depth and opening format to your property layout, elevation style and long-term maintenance preferences.
Contemporary Flat Sash
A clean modern profile that suits new extensions and design-led renovations where minimal framing is a priority.
Flush Sash Styling
Flush sash routes deliver a more traditional external appearance while retaining aluminium strength and modern glazing options.
Open-Out Combinations
Top-hung, side-hung, fixed-light and multi-light formats can be configured around ventilation needs and room layout.
Internal Design Continuity
Hardware and finish choices can be aligned across windows and doors for a consistent whole-home design language.
Performance and Compliance Focus
Every installation is scoped around measurable outcomes: thermal comfort, reliable security and compliance-ready specification decisions.
Energy Efficiency Planning
Current supply pathways include U-value routes around 1.4 W/m2K with double glazing and lower routes with triple glazing, subject to full specification.
Security-Led Specification
Multi-point locking, reinforced hardware and tested window formats can be configured to meet security priorities and project requirements.

Frequently Asked Questions
Straight answers to common questions before you commit to final specification.
Are aluminium casement windows suitable for period properties?
Yes. Flush sash and heritage-style aluminium systems can preserve traditional proportions while delivering modern performance and lower maintenance than timber.
Can I choose both double and triple glazing?
Yes. Double glazing is typically the default route, while triple glazing can be specified where project goals demand stronger thermal or acoustic performance.
Do aluminium casement windows support stronger security standards?
Yes. Multi-point locking is standard on modern systems, with upgrade routes available for PAS 24 and Secured by Design aligned projects.
What colours are available?
You can choose from popular fast-delivery shades and a broad RAL range, including dual colour options to coordinate external and internal finishes.
How do I know which frame depth and sash option to choose?
We confirm this during survey by balancing sightline preference, opening size, property style and performance targets before final specification.
