Nordan Fully Glazed Double Patio Door Aluminium, Black

The NorDan NTech BlackLine Fully Glazed Double Patio Door combines an all-black modern design with aluminium cladding, low U-value thermal efficiency, and reinforced security.

The NorDan NTech Fully Glazed Double Patio Door from the BlackLine series delivers contemporary architectural style along with superior security and energy performance. Designed to create a smooth transition between indoor living areas and outdoor terraces, this double door allows maximum daylight to flood your interior through expansive glass panes.

Featuring a comprehensive all-black finish, the BlackLine concept coats the exterior in durable powder-coated aluminium in RAL 9005 black, while the interior timber is painted in matching deep black. Details including the warm-edge spacer bars, weather stripping, and hardware fittings are consistently styled in black to ensure a unified, sophisticated aesthetic.

Built with energy performance at its core, the patio door incorporates high-insulation triple glazing filled with argon gas and equipped with warm-edge spacers, delivering an impressive U-value of 0.9 W/m²K. The glazing is secured using NorDan ND-secure under-sealing technology, providing exceptional thermal retention, draught exclusion, and acoustic insulation rated at 33 dB.

Security is integrated at every level. The doors feature hardened and laminated safety glass on both sides, robust adjustable hinges with double back-edge protection, and an integrated Fix 150 brake mechanism for secure ventilation and position holding.

The low-profile threshold is constructed from FSC-certified hardwood protected by an aluminium tread, measuring just 25 mm high for smooth accessibility. The aluminium cladding on the exterior ensures minimal maintenance and long-lasting resilience against challenging weather conditions.
