What makes a good quality aluminium window?

A good quality aluminium window should excel in four key areas:

Uncompromising durability and security, top-of-the-line energy efficiency, unparalleled sightlines and as much customisability as can be offered.

If satisfied, these four pillars of good quality aluminium windows will leave you with a premium product that stands tall above other, less-premium window types.

The best-quality aluminium windows begin with the manufacturer, and making sure you know what to look out for is crucial in choosing the cream of the crop.

What to look for when buying aluminium windows?

When looking for the perfect aluminium windows, everything from manufacturing standards to finish quality should be considered.

In your aluminium windows, make sure you look for:

• Easy to maintain finishes
• Advanced locking mechanisms
• Thermally-efficient glazing
• Made-to-measure manufacturing
• Industry-tested performance
• Fully-customisable frames
• Sustainably sourced aluminium
• Long, insurance-backed guarantees
• Trusted manufacturers.

The Heritage Window Company is passionate about aluminium windows, which is why we excel in all of these areas – from 10-year FENSA guarantees to over 200 RAL colours and ancillaries to choose from, PAS24-tested locking systems and sustainably sourced aluminium.

Aluminium window style

We offer five exemplary aluminium window styles to choose from, including Victorian-inspired styles and perfect replacements for steel windows.

Here’s what makes these styles a great choice, at a glance:

Slimline aluminium windows: Ultra-thin frames that maximise sightlines while delivering robust strength, thermal efficiency, and modern performance. They’re ideal when you want a sleek, contemporary aesthetic with high durability, security, and energy-saving benefits.

Benenden conservation windows: Inspired by the traditional stylings of traditional steel-framed windows, these efficient windows conform to both replacement and new-build regulations – perfect to satisfy planning requirements.

Shaped aluminium windows: Designed to match any architectural profile, these uniquely-shaped windows are made-to-measure, with all the energy-efficiency upgrades and slim frames you’d expect from our other aluminium window styles.

Curved windows: Bespoke, art-deco-inspired frames that offer sweeping panoramic views with slim profiles and high thermal and acoustic performance.

Aluminium sash windows: Georgian- and Victorian-inspired frames that allow homeowners to uphold their home’s original stylings whilst also improving security and efficiency.

Thermal efficiency

Increasing energy efficiency with aluminium double glazing is a simple, cost-effective process that prevents energy leaks in the home – perfect for saving on household bills.

Our in-house engineering team construct incredibly thin frames with the highest precision, allowing the frames to fit together with no small gaps or joints where heating could escape.

This ensures higher efficiency ratings, warmer homes and lower bills – especially in older properties that struggle with heat loss.

Aluminium window security

The perfect aluminium windows take security seriously, which is why our windows come with the same improved locking systems as our aluminium doors.

Enjoy a PAS24-rated multipoint locking system, ensuring enhanced security for your home that operates seamlessly with the slimline aluminium frames, providing robust protection without compromising on the slim frames you’ve come to expect.

Aluminium window customisability

Aluminium windows offer the highest level of customisation on the market, which is why you should take advantage of the optional colours, accents and ancillaries available to you.

Our windows have more than 200 RAL colour options to pick from, so whether you opt for a minimalist black, traditional olive green, or a contrasting colour that matches your front door, speak to our design experts to explore all your options.

Conservation area or property requirements

When choosing new windows, it’s important to consider any conservation or property-specific requirements that may apply. Many older or listed buildings are subject to planning restrictions that dictate the style, material, and proportions of windows to preserve the property’s historical character.

Our experts can help you work within these frameworks, with specific window styles designed to help conform to building regulations, such as the Benenden Conservation windows and our Secondary Glazing windows – discreet secondary aluminium windows added to existing frames, enhancing performance and energy efficiency without compromising the original window.

Price and value for money

Once you’ve considered all the factors discussed, it’s important to set a budget and be sure you’re paying for the true value of your upgraded windows.

At The Heritage Window Company, we don’t have a set fee – we price every job uniquely to the service provided, fully costed and appropriately valued. That’s because no two homes or windows are the same, and you should expect unique pricing to reflect your installation.

Window provider reputation

If you’re ready to book a design visit or request a quote, fully research the reputation of potential window providers before you reach out.

A reputable window provider will have reviews that ensure quality, durability, and reliable aftercare, so make sure you check customer satisfaction ratings on Trustpilot and Google beforehand.
