GARDEBRUK® 14x Polycarbonate Twin Wall Sheets | 4mm | 10.25 m² | Double Wall | Roofing | Greenhouse | Clear | Multi Panels Plastic | Outdoor | Canopy | Cold Frame | 121x60.5cm

Great price for a great product, I’ve just replaced my greenhouse roof in only a few hours & I’m delighted with the finished result. The polycarbonate sheets were very easy to cut to size with a sharp Stanley type knife & a good straight edge as a guide. The thickness of 4mm was exactly what I needed for the job, the finished work looks like I’ve got a new greenhouse.The sheets were a lot cheaper than buying off of the internet by using Amazon, I even got free shipping all the way from Germany and they arrived within days of my order with full communication of the shipment from the courier….totally delighted

A good product, buying this way is great value. But the delivery was chaotic - for some reason a call was going to happen - it didn't and then product just arrived although quickly. The large package was left on a flower bed near my front door squashing the plants which was annoying and ironic. One corner of the package was damaged - probably by the same courier that squashed my garden plants.The panels are lightly packed, are clear and bright though some were damaged to one corner during delivery - see above comment - but as various trimming was going to be required this was not an issue.The panels are manufactured at correct width for widest panel of a standard greenhouse. Narrow panels are easily trimmed to size with a sharp / new stanley knife blade and a straight line on a flat surface.Elsewhere on Amazon I bought "glazing "w" wire clips and "z" overlap clips" and they work perfectly with these polycarbonate sheets.I don't expect these panels will last for more than a few years due to the impact of UV on plastics but at the moment the greenhouse is once more warm, bright and draught free.The only reason I dropped a star was the (non Amazon) delivery which was confused and careless.

very happy

I built a greenhouse a few years ago and wanted to refresh the glazing these were perfect for the job, arrived swiftly and well packaged, and both sides were plastic-covered. they easily fitted as I expected. easy to cut the sides are not realed so I did have to tape those up, but this is normal. 4mm is quite thin but for my requirements was perfect and still quite sturdy given the thinness.

Replaced my greenhouse with 2 boxes. A third the price of glass can't fault it thanks

Looks a bit flimsy, certainly more than I anticipated; the standard width 60.5cm is a tiny bit narrow for an "imperial" greenhouse - I'd have preferred the extra half inch width, but the panels have fitted in. They are more flexible than I had anticipated and somewhat opaque - not transparent, but translucent. Easy to cut when needed, the good news is there are less joins in the panels than with glass and the pre-cut edges look good when in place.I called the company to check sizes and quantities before ordering and they promptly increased the price per pack by about £7 before I ordered (took away delivery charge which I probably wouldn't have had to pay anyway). I thought that was a bit cheeky and gave me a rather negative impression. Will be interesting to see how they perform.

As advertised bought to buil a green house but should have went for the 6mm thickness

Great product prompt delivery good value for money
