Storm-Proof (Double Gasket)

Our Storm-proof casement window features overlapping lipped openers on the outside (overlapping the external face of the frame) with a double gasket system, which makes it altogether more weather proof and more secure.

Additional Features of This Window System

  • Openers overlap the frame on the outside and are sealed with another gasket giving you a Double gasket system, meaning more insulation, more windproof and more secure.
  • Available only with Friction Stay Hinges (Optional Egress opening to 80 to 90 (degrees) for Fire regulations or just a better view or for Safety we can offer Restricted opening hinges)
  • High security multi-point window locks with Night ventilation locking for safety (except on Floating Mullions)
  • Externally glazed as standard but we can do internal glazing if preferred for this system
