Aluminium frames offer an exceptional combination of structural strength and slim profiles, making sliding aluminium doors one of the most effective ways to achieve large glass panels and unobstructed views without heavy, visually dominant framing. This makes them an excellent option for contemporary living spaces and open-plan extensions.
The longevity of aluminium and its resistance to harsh weather conditions mean these systems are a smart investment over the long run. Powder coating is applied to a full range of colours and is highly resistant to fading, corrosion, and weathering – so the home’s aesthetic appeal is preserved year after year with very little maintenance.
The Reynaers MasterPatio and Schüco ASS 70 HI are both outstanding in their own right, and the right choice will depend on the specific glazing and performance requirements of your project. Our technical team can walk you through both options in detail to ensure you select the system best suited to your project’s brief.
Both systems are available in a range of colours, with dual-colour finishes to differentiate the interior and exterior faces. Security features on both meet stringent international standards, giving homeowners and specifiers confidence in the performance of their investment alongside genuine peace of mind about safety and weather resilience.
