Evalock’s top hung awning window has the winding mechanism fitted at the base and flyscreen fitting to the inside of the window. This allows greater security, opening only 300mm hence allowing better viewing without centre rails.

This is the most economical of windows to manufacture. They are able to be double glazed and when fitted with weather sealing are draught proof.

Evalock’s awning windows have been tested and found suitable for:

  • N4 Housing Rating
  • 1500 Pascal Design Rating
  • 1000 Pascal Water Penetration Rating
  • Air Conditioned Rating
