Janssens Side Push Open Tilt Window - VI-SW-B

The Janssens Side Push Open Tilt Window can be added to any Royal Victorian or Junior Victorian Greenhouse kit at the time of order.  It is hinged at the top and opens with a handle at the bottom.  These come in black or fir green.  The tilt window features a glass panel and an extra glass piece for underneath the window for Royal Victorian or Junior Victorian Greenhouse.

All standard Royal and Junior Victorian Greenhouses already include one louver window.  You can add as many of these push out windows as you want to your greenhouse with the caveat that you cannot put windows adjacent to each other - so "every other panel" would be the most you can add.  Auto-openers and fly screens are available.

Maintenance Tips
  • Clean the window glass and frame regularly with a soft cloth and mild glass cleaner to maintain clarity and finish.
  • Check the push-open and tilt mechanism frequently to ensure smooth and easy operation.
  • Lubricate hinges, pivots, and moving joints periodically with a silicone-based lubricant.
  • Inspect screws, brackets, and fixings regularly and tighten any loose components.
  • Ensure the tilt function is fully functional and not obstructed by dirt or debris.
  • Avoid using abrasive cleaners that may scratch the frame or damage protective coatings.
  • Check seals and edges seasonally to maintain proper insulation and weather resistance.
  • Keep the surrounding area clear to prevent strain on the opening mechanism.
