Shed Windows | Greenhouse Windows

On this page you can buy replacement windows and panels for sheds and greenhouses in either Perspex® Acrylic or Lexan® Polycarbonate in a choice of standard thicknesses.

Our replacement shed and greenhouse windows and panels are perfectly clear and less than half the weight of glass, and a perfect choice to replace yellowed, broken or old shed and greenhouse windows with new window panes. They're great for replacement cold frame glass panels, summerhouse windows and replacement playhouse windows too.

We'll cut your new shed windows to your exact sizes so you don't have to worry about trimming as you might with shop bought standard sizes.

Our Perspex® and Lexan® grades are UV treated to last longer outside than cheaper alternatives - in fact, you can be confident that our replacement panels will stay clear for at least twice as long compared to non-UV treated materials!
