As relative novice in the fenestration business while overseeing the development of a personal building project at the same time, I can understand how overwhelming it can be for homeowners in South Africa to differentiate between various brands of aluminium windows and doors, especially when they all claim to offer the “highest-quality products” that are immediately available and at remarkably affordable prices.
How does one tell them apart, you ask? In my experience and without getting too technical, let me break it down for you with a couple factors that you can consider to distinguish a high-quality European system like Reynaers Aluminium, from locally available products that claim to be “high quality”.
- Design and Engineering: European systems, such as Reynaers Aluminium, are designed and engineered with the latest technology and innovative techniques, which ensure that they meet the highest standards of quality and performance. These systems are rigorously tested for their durability, weather resistance, energy efficiency, and sound insulation. Performance test reports, on wind-loads for example, will always be readily available.
- Material Quality: The quality of the material used in the manufacturing of windows and doors is crucial in determining their performance and longevity. Reynaers Aluminium, use high-grade aluminium, which is lightweight, strong, and highly resistant to corrosion and wear. In comparison, some local brands may use lower-quality materials or alloys, and may skimp on the thickness of their profiles, which can compromise the overall quality, integrity and durability of the product.
- Manufacturing Standards: Reynaers Aluminium systems are manufactured using state-of-the-art equipment and stringent quality control processes that ensure consistency in product quality. The manufacturing processes used by local brands may not always adhere to the same level of quality control, which can result in products that are not as reliable or long-lasting.
- Certification: Look for certifications and accreditations from reputable industry bodies. European systems like Reynaers Aluminium are often certified by independent organizations, which guarantees that their products meet strict quality and safety standards. Some local brands may also have certifications and accreditations, so it’s worth checking for these. Reynaers products for example, carry a CE-marking– an internationally recognized European quality label awarded to products that meet high standards in various domains, ranging from safety to health and environmental issues.
- Warranty: A manufacturer’s warranty can give homeowners peace of mind knowing that their investment is protected. Reynaers Aluminium, offer longer warranties that cover a wider range of potential issues. Local brands may also offer warranties, but they may not be as extensive in coverage and duration.
- Sustainability: being conscious of the aluminium industry’s ecological footprint, it’s important to consider whether the brand is taking steps to counter this impact. As Reynaers’ global sustainability strategy outlines, they’re taking action to develop circular products that contribute to more sustainable buildings. Look out for the range of Cradle to Cradle Certified solutions across all product categories.
- Aesthetics: The cherry on top! Not only does a superior quality product meet all the above performance criteria, but they also look darn sexy! With systems and design variant options from Reynaers Aluminium, you’re not limited to just a standard bulky, square profile & configuration.
So there you have it, while many brands claim to offer high-quality aluminium windows and doors, factors such as design, engineering, material quality, manufacturing standards, certification, and warranty can help you differentiate between a more expensive European system like Reynaers Aluminium which you may have to wait a little for, and cheaper, locally available products in South Africa.
It’s always a good idea to do your research, compare products and consult with experts to help you make an informed decision that best meets your specific needs and budget. Connect in South Africa with a local Reynaers specialist here
