HS99 Aluminium Horizontal Sliding Window – 900 × 900mm

The HS99 aluminium horizontal sliding window is a compact 900 × 900mm two-panel window with one fixed panel and one sliding panel. The opening sash slides horizontally within the frame, providing practical ventilation without projecting outward.

Ideal for bathrooms, kitchens, bedrooms and smaller openings, the HS99 is supplied as a complete glazed window with handle, latch, rollers and weather seals.

Standard Size 900 × 900mm Aluminium Sliding Window

The HS99 is a practical standard-size window for smaller openings. Its horizontal sliding design provides natural light and ventilation while keeping the opening sash within the window frame.

Ideal Aluminium Bathroom Window Size

This makes it particularly useful where there is limited space outside the window or where an outward-opening sash would be inconvenient.

Suitable Area	Recommended Glass
Bathroom	Frosted
Kitchen	Clear
Bedroom	Clear
Passage / Utility Area	Clear or Frosted
Other Small Openings	Clear or Frosted

Horizontal Sliding Operation

The HS99 consists of one fixed glazed panel and one sliding sash. The opening panel moves horizontally on rollers within the aluminium frame and is secured with a latch when closed.

The simple sliding operation makes this a practical, easy-to-use window for everyday residential applications.

Choose Your Opening Direction

The HS99 can be ordered with the handle on the left or handle on the right when the window is viewed from outside.

When ordering, always select the opening direction as you would see the window while standing outside the building and looking towards it.

Viewed From Outside	Select
Handle is on the left	Handle on Left
Handle is on the right	Handle on Right

This allows you to choose the sliding configuration that best suits the room layout, access and position of the window.

Clear or Frosted Glass

The HS99 is available with two glass options:

Clear Glass — provides maximum natural light and a clear view through the window. A practical choice for kitchens, bedrooms and general residential applications.

Frosted Glass — provides privacy while still allowing natural light into the room. It is particularly suitable for bathroom windows and other areas where privacy is required.

Aluminium Frame Colours

Choose from Natural Anodized (Silver), White, Bronze, Charcoal or Black to coordinate the HS99 with other aluminium windows and doors in your home or project.
