Sliding Door Information

The HS 330 timber-aluminium lift and slide door creates a fluid connection between indoor and outdoor spaces—delivering elegant design, robust performance, and smooth accessibility. Designed to match Internorm’s timber-aluminium window range (HF 410, HF 510, HF 520, and HV 450), it offers coordinated timber finishes and colours for a unified architectural look.

With Uw values of up to 0.73 W/m²K, the HS 330 provides excellent thermal insulation. Its fibreglass threshold, reinforced with anodised aluminium, ensures long-term stability and durability. The fixed glazing option supports a clean, frameless glass aesthetic, allowing rendering on three sides for a minimalist, modern finish.

The lift and slide mechanism ensures smooth, effortless operation, while an integrated soft-close mechanism gently slows the door before closing—preventing slamming and helping extend its lifespan. For added convenience, the optional Comfort Drive enables electric opening and closing at the push of a button. Fully concealed locking and security options up to RC2 complete the package—delivering a stylish, secure, and energy-efficient solution for contemporary living.

Features:

  • Material: Timber interior, Aluminium exterior
  • Design Cohesion: Matches timber options and colours of HF 410, HF 510, HF 520 and HV 450 windows.
  • Threshold: Fibreglass with anodised aluminium cover (for thermal insulation and stability).
  • Fixed Glazing Design: Renderable on three sides for a perfect glass design.
  • Optional Feature: Comfort Drive - electric drive for automated opening and closing.
  • Construction Schemes: Scheme A, C, G, fixed elements, all-glass corners.
  • Customisation: Wide range of RAL colours for the interior, and various timber options (spruce, larch, oak, walnut). Anodised, RAL, textured, metallic, and wood decor colours for the exterior aluminium.

  • Creates a harmonious living space by matching window designs.
