Introduction

The top-hung window is manufactured in high quality pine with the option of a white painted internal finish (GPL) or white polyurethane internal finish (GPU). It is suitable for installation into roof pitches between 15° and 55°. For installations between 55° and 75° special springs will be required.

Not advised for high level (out of reach) installation. The bottom edge of the window should be placed approx. 0.90 – 1.20m above the floor for ease of operation.

Roof pitch
15o-55o
Features
  • Ventilation bar with dust and insect filter – Allows fresh air to enter the room while the window is securely closed
  • Sash rotates 180° from inside – Allows easy and convenient cleaning
  • Barrel bolt – Allows the window to be locked in to position at 180° for secure cleaning of the exterior pane internally
Operation
The sash which is top-hung is opened and closed using the bottom handle and can remain open in any position up to 45 degrees.
