Premium Cortizo Bi-Fold Doors for Modern Living
Cortizo bi-fold doors represent the pinnacle of modern architectural glazing, offering homeowners and developers an exceptional combination of performance, aesthetics, and functionality. These premium aluminium bi-fold doors feature a robust 73mm frame depth that provides superior thermal insulation and acoustic performance, making them ideal for the UK's moderate climate conditions.
The Cortizo system excels in creating seamless indoor-outdoor living spaces, with the ability to accommodate up to 14 sashes in both inward and outward opening configurations. This flexibility allows for maximum design freedom, whether you're creating a grand entrance to your garden or a sophisticated connection between living areas. The system's advanced engineering ensures smooth operation even with the heaviest configurations, supporting sashes up to 120kg each.
Security is paramount with Cortizo bi-fold doors, featuring PAS 24 security testing and advanced multi-point locking mechanisms. The system's robust construction, with 1.8mm profile thickness, provides peace of mind while maintaining the elegant, slim-line appearance that modern architecture demands. The doors achieve exceptional performance ratings including Class 4 air permeability, Class 9A water tightness, and Class A3 wind resistance.
Superior Thermal Performance and Energy Efficiency
The Cortizo bi-fold door system is engineered for energy efficiency, achieving a thermal transmittance (U-value) of UD ≥ 0.97 W/m²K. This impressive performance is achieved through the system's 73mm frame depth and advanced thermal break technology, which significantly reduces heat transfer and helps maintain comfortable indoor temperatures throughout the year. The system supports glazing units up to 45mm thick, allowing for the integration of high-performance double or triple glazing to further enhance thermal efficiency.
For homeowners looking to reduce their carbon footprint and energy bills, Cortizo bi-fold doors offer an excellent solution. The system's thermal performance helps meet and exceed current building regulations, making it an ideal choice for both new builds and renovations. The doors' ability to create large openings while maintaining excellent insulation properties allows for maximum natural light without compromising on energy efficiency.
Versatile Design Options and Premium Finishes
Cortizo bi-fold doors are available in an extensive range of finishes to complement any architectural style. The system offers dual colour systems, allowing different finishes on the interior and exterior faces, perfect for projects requiring specific design coordination. Powder coating options include standard RAL colours, mottled and rough finishes, and innovative wood effect coatings that provide the warmth of timber with the durability of aluminium.
For healthcare and commercial applications, Cortizo offers anti-bacterial powder coating options that help maintain hygienic environments. Traditional anodised finishes are also available for projects requiring a more classic appearance. The system's corner solutions enable seamless 90° corner configurations without visible mullions, creating uninterrupted views and maximising the connection between indoor and outdoor spaces.
