Well packaged, timely delivery. Good quality

Shed replacement windows, arrived very well packaged. They look great!

I replaced the windows in my garden workshop, they are an excellent product and I would highly recommend them

I had previously made a cover for a plant propagator of my wife's, out of plastic sheet secured to corner pillars of aluminium angle by nuts and bolts. She is a very active gardener and the propagator served well but had a fairly hard life. For its replacement I was pleased to find online the possibility of getting pre-cut stronger sides and have been really pleased to be able to make such a clear strong new cover using only powerful adhesive.

I used this product to replace 2 shed windows. Item arrived promptly and was perfectly cut to size. Very pleased with how they look.

Great price, very pleased with delivery and packaging. Hubby has drilled holes to secure to shed window frames with no problems. Very pleased, seem like they will last a lot long than normal plastic shed windows.

We replaced the windows in our summer house. The ones which came with the summer house were very flimsy and easily damaged. The polycarbonate replacement windows were much better quality, sturdier and cut to size (apart from the 6 for the doors which needed trimming as the size was below the minimum the company sell. But it was no bother for my husband to cut them.) Delighted with the product, and with the prompt service. Summer house looks fabulous. Highly recommend this company.
