Choosing new windows is an investment that will last for many years. But how can you tell if you're choosing high-quality aluminium windows? At first glance, many systems may look similar, yet the differences in performance, finishing quality, and durability can be substantial. Aliplast highlights the key aspects to pay attention to.
Pay attention to insulation performance
In the past, aluminium was sometimes perceived as a less insulating material, but those days are long gone. Modern aluminium windows feature advanced thermal breaks and multi-chamber profiles that significantly reduce heat loss. Combined with high-performance glazing, they achieve excellent insulation values and comply with the most demanding energy standards. When evaluating windows, always ask your window manufacturer about the insulation values. The lower these values, the better the thermal performance of the window.
Aliplast windows are equipped with advanced thermal break technology, delivering outstanding insulation performance and easily meeting the requirements of today's energy-efficient homes. Aliplast even offers aluminium profile systems suitable for passive house applications, where energy efficiency is taken to the highest level.
Check the quality of the coating
The finish of aluminium windows not only determines their appearance but also has a major impact on their lifespan. A high-quality powder coating protects the aluminium against UV radiation, weather exposure, and corrosion. It is therefore important to ask about quality labels and certifications. These labels guarantee that the coating meets strict requirements in terms of colour retention, adhesion, and weather resistance.
Aliplast selects premium coatings that comply with the internationally recognised Qualicoat standard. The Qualicoat label guarantees that the powder coating applied to aluminium meets stringent requirements for adhesion, colour stability, weather resistance, and corrosion protection.In addition, our coating warranty is backed by the Qualicoat Seaside label, providing enhanced protection in aggressive environments such as coastal areas and locations exposed to traffic emissions or industrial pollution. A long colour warranty is also a strong indicator of quality. For example, Aliplast offers a standard 15-year colour warranty, and for selected colours this can be extended to up to 25 years.
Ask about test results and certifications
High-quality aluminium windows are extensively tested for a wide range of performance criteria, including air tightness, water tightness, wind resistance, burglar resistance, and acoustic insulation. Independent certifications and test reports provide additional assurance that a window system delivers what it promises.
Consider the strength of the profile
One of the key
advantages of aluminium is its exceptional strength. This makes it possible to
create large glazed areas without the need for bulky or wide profiles. Slim
aluminium profiles maximise natural light and provide an elegant, contemporary
appearance without compromising stability or structural performance.
For homeowners and
architects who dream of large windows, sliding doors, or minimalist
architecture, this is an important characteristic to consider when selecting a
window system.
Pay attention to security
Quality windows also contribute significantly to the security of your home. That is why it is important to ask about the available security options. Many aluminium window systems can be equipped with RC2 or RC3 security hardware, providing enhanced resistance against burglary attempts. A strong profile combined with high-quality locking mechanisms and fittings can make a substantial difference.
Aluminium is naturally a very strong and robust material, making it difficult to force or damage. When combined with certified burglar-resistant hardware, it offers an exceptionally secure solution for residential properties. In general, the stronger the window profile, the more difficult it is for intruders to gain entry by force.
Check the maintenance requirements
A high-quality window should not only look great on the day it is installed, but also many years later. Aluminium windows are highly resistant to rust, cracking, and warping, while retaining their colour and appearance over time. Aluminium windows do not require painting. Maintenance is generally limited to periodic cleaning with water and a mild detergent. To preserve their optimal shine and colour retention, a single annual treatment with a protective maintenance product is usually sufficient. This makes aluminium an exceptionally low-maintenance and durable choice for both new-build and renovation projects.
Ask where and how the system is manufactured
The manufacturing process has a major impact on the final quality of the windows. Aliplast, for example, manufactures entirely in Belgium and maintains control over the entire production chain, including powder coating. A transparent window manufacturer will be happy to explain how its profiles are developed, tested, and produced.
Conclusion
High-quality aluminium windows can be recognised by much more than their appearance alone. Good insulation values, strong and durable profiles, a high-quality coating finish, comprehensive certifications, enhanced security, and a long service life are all key indicators of quality. By asking the right questions, you can gain a clearer understanding of the actual performance and reliability of the system. Investing in high-quality aluminium windows means investing in durability, comfort, security, and a timeless aesthetic that will stand the test of time for many years to come.
