What Does "Prehung" Mean?
A prehung door set means the doors are already mounted within their frame before delivery. This significantly simplifies installation — the entire unit (frame, doors, and hinges) is fitted into the structural opening as one assembly, rather than hanging individual doors into a separately installed frame. Prehung sets ensure correct alignment and are the preferred choice for new builds and full renovations.
Why Choose an Aluminium Full Glass Door?
Aluminium full glass doors are a popular choice in South African residential and architectural design for several reasons. The slim aluminium profiles maximise the glazed area, flooding interiors with natural light and creating a seamless visual connection between indoor and outdoor spaces. Anodized aluminium requires no painting or sealing and resists rust, making it ideal for South Africa's varied climate — from humid coastal regions to dry inland areas. Toughened safety glass provides impact resistance and, if broken, shatters into small blunt fragments rather than dangerous shards.
Typical Applications
The DHD1821 is well suited to: main entrance doors for homes and apartments, patio and veranda access doors, and architectural feature entrances in commercial or hospitality settings.
Installation Notes
Professional installation is strongly recommended for this 120kg double door set. Ensure the structural opening is plumb, square, and level before fitting. Handles and lock are supplied loose and must be fitted on site. Apply appropriate sealant around the frame perimeter after installation to prevent water ingress.
