HS306 Aluminium Horizontal Sliding Window – 3000 × 600mm

The HS306 aluminium horizontal sliding window is a wide 3000 × 600 mm four-panel window with an OXXO configuration. It has two fixed outer panels and two sliding centre sashes, providing a balanced appearance with practical ventilation through the centre.

Its wide, low-profile design makes the HS306 suitable for garages, kitchens, living areas, entertainment spaces and other wide wall openings where an outward-opening window would be inconvenient. Sigmadoors currently lists the HS306 as part of its Icon Series horizontal sliding range.

Wide 3000 × 600mm Aluminium Sliding Window

At 3 metres wide and 600mm high, the HS306 is a practical choice for wide horizontal openings where natural light and ventilation are required without using a full-height window.

Its low-profile design works particularly well in garages, bedrooms, passages, utility rooms, kitchens and living areas. Because the two opening panels slide horizontally within the frame, no additional space is required for outward-opening sashes.

Suitable Area	Why It Works
Garage	Provides natural light and ventilation along a wide wall
Bedroom	Wide glazing provides good daylight and ventilation
Passage	Brings natural light into long or narrow circulation areas
Utility / Laundry	Practical ventilation without an outward-opening sash
Kitchen	Works well above counters or along wider wall openings
Living Area	Provides a wide horizontal view and natural ventilation

OXXO Four-Panel Sliding Configuration

The HS306 uses an OXXO configuration:

O — Fixed panel | X — Sliding panel | X — Sliding panel | O — Fixed panel

The two centre panels slide away from the centre towards the fixed outer panels. This creates a symmetrical opening in the middle while retaining fixed glazing at both ends.

Clear or Frosted Glass

Choose Clear Glass for maximum natural light and visibility, or Frosted Glass where additional privacy is required. Sigmadoors currently offers both clear and frosted/obscure glazing selections for this product.

Aluminium Frame Colours

The HS306 is available in Natural Anodized (Silver), White, Bronze, Charcoal or Black, allowing it to coordinate with other aluminium windows and doors throughout the building.
