Sleek, Slimline Frames with Maximum Natural Light
Aluminium is significantly stronger than many alternative materials, allowing for slimmer frames and larger panes of glass. This creates a brighter, more open feel while maintaining exceptional structural strength.
Slimline aluminium windows are ideal for contemporary homes, extensions and modern refurbishments where clean lines and maximum glazing are key.
Excellent Energy Efficiency with Thermal Break Technology
Our double glazed aluminium windows are engineered for strong thermal performance. Each frame includes an integrated thermal break that reduces heat transfer, working alongside high-performance sealed glass units to improve insulation throughout the year.
If your existing glazing has failed or become misted, we also offer double glazed glass replacement as a cost-effective alternative to full frame replacement.
Strong, Durable & Built for UK Weather
Aluminium is naturally resistant to warping, cracking, rotting and fading. Powder-coated finishes provide long-lasting protection against the elements, ensuring your windows maintain their appearance and performance for decades.
This makes aluminium particularly well-suited to exposed or coastal locations where durability matters most.
Low Maintenance & Long Lifespan
Unlike materials that require repainting or ongoing treatment, aluminium windows are virtually maintenance-free. Their durable finish ensures they retain their sleek appearance with minimal upkeep.
With proper installation, aluminium frames can last 40 years or more, making them a long-term investment in your property.
High Security as Standard
Every aluminium window we install is designed with security in mind.
Multi-point locking systems
Toughened or laminated safety glass options
Reinforced aluminium frames
High-security hardware
These features combine to provide dependable protection without compromising style or usability.

Aluminium vs uPVC – Which Is Right for You?

Are aluminium windows better than uPVC?
Aluminium windows offer slimmer frames, greater strength and a longer lifespan than uPVC. They’re ideal for modern homes and extensions where a clean architectural look is important. Many customers choose aluminium for its durability and enhanced security.
How long do double glazed aluminium windows last?
High-quality aluminium windows typically last 40 years or more, thanks to their resistance to weather, corrosion and wear. Double glazing units inside the frame usually last 15–25 years depending on conditions.
Can aluminium windows improve insulation?
Yes. Modern aluminium windows include thermal breaks and high-performance double glazing, significantly reducing heat loss. Many homeowners notice fewer drafts and lower heating bills after upgrading.
Can you replace just the glass in my aluminium window?
Yes, if the frame is still in good condition, we can replace the double glazed glass unit only. This is ideal for condensation between panes, misting or cracked glass.

How much double glazed windows cost?
