Aluminium Windows

Given the UK's unpredictable weather, aluminium is an ideal choice. These windows require almost no maintenance, offer excellent energy ratings (low “U” values), and look fantastic.

The aluminium casement system works perfectly for both homes and businesses. Whether you are replacing old windows or starting a new build, we can help. Our windows come in any RAL colour to match your dream home. We also offer "Slim Line" options, which use thin frames to allow the maximum amount of natural light into your rooms.

While there are many styles available - including sliding sash, flush casements, and heritage styles that look like traditional steel - the casement window remains the most popular choice for modernising a property.

Popular Colour Options:

• Slate Grey (RAL 7015)

• Anthracite Grey (RAL 7016)

• White (RAL 9010)

• Plus hundreds of other custom RAL colours!

1. Built to Last

Aluminium casement windows are much stronger than vinyl (uPVC) or wood.

• Weather resistant: They do not warp or bend due to heat or humidity.

• Tough: Unlike wood, aluminium does not rot and is immune to pests.

• Long-lasting: Because they don't need frequent repainting, they are a very cost-effective long-term investment.

2. Simple Maintenance

Keeping your windows looking new is easy. You don't need to worry about regular sanding or sealing.

• Cleaning: Simply wipe the frames with water and a mild detergent.

• Operation: Occasionally check and grease the hinges and locks to keep them moving smoothly.

3. Energy Efficiency & Comfort

Modern aluminium windows are designed to keep your home warm and your bills low.

• Double Glazing: Provides a thick layer of insulation to keep heat inside during winter and outside during summer.

• Thermal Breaks: We use advanced technology inside the frame to stop heat from escaping.

• Soundproofing: The tight seals and quality glass help block out street noise, making your home a quiet sanctuary.

4. Style and Customisation

Aluminium is incredibly versatile. It can be powder-coated in almost any colour or finish. Whether you live in a traditional Victorian house or a minimalist modern home, we can tailor the design to match your architecture perfectly.

Our anthracite grey aluminium windows in RAL 7016 offer a sleek, contemporary finish ideal for modern homes and extensions.
