You cannot fault Harrod's service Products arrive quickly. The 20mm Bubble Wrap is easy to handle, looks well in the greenhouse and should make a big difference to heating costs. Difficult to tell how much it saves as we are having a mild winter! No doubt if I hadn't bought it. we would have been under 3 feet (1metre) of snow!!
Bubble wrap arrived quickly and was soon put on my fathers greenhouse. It is easy to handle and appears to be strong and has made a tremendous difference to the heat retention of the greenhouse. Only 4 stars for performance as only time will tell regarding its lasting abilities, but all round very impressed.
This product is well made and easy to fit, it has not yet been cold enough to tell how it will perform in below freezing temperatures. The delivery service was outstanding I rang just after the deadline for next day delivery not expecting it to arrive the following day, however I was delighted when it did arrive the next day.
How to Insulate the Greenhouse
It’s a great idea to line the inside of your greenhouse during the winter – it’s economical, quick, will frost-proof the structure and can extend the growing season for up to 6 weeks. Working out how much bubble insulation (product code GHE-015) you need and just how to fit it can be a problem, so the chart below will give a rough guide to what you’ll need!
Size of Greenhouse (feet) Amount of Bubble Wrap Required
6 x 4 14m (2 rolls, 1.5m wide)
6 x 8 18m (2 rolls, 1.5m wide)
8 x 10 21m (3 rolls, 1.5m wide)
8 x 12 27m (3 rolls, 1.5m wide)
Don’t forget to allow 3 alliplugs (GHE-009) and spacers (GHE-010) per glazing bar; likewise with the corner adaptors (GHE-011).
When fitting the insulation, the following information may help.
- Measure from the floor to the apex of the greenhouse up one side and back down other, and cut the insulation to length.
- Go to the back of the greenhouse, away from the door then fold the insulation in half and secure the middle to the top ridge.
- Work along each glazing bar securing the insulation to the roof and sides with the alliplugs.
- Have a sharp knife handy to cut the bubble wrap where the vents and windows are sited. Repeat for the next panel, gradually working towards the door.
- The end panel which includes the door is best tackled by attaching the insulation to the outside of the structure, cutting to size and then securing inside.
- Simply cut the insulation which covers the door as this will allow both access and the bubble wrap to hang down – it’s a good tip to allow extra bubble wrap below the door which you can fold and weigh down, allowing less cold air to enter.
What The Press Say
On Test - Indoor Growing - Dave Finkle
This bubble wrap has 20mm air pockets which creates more efficient thermal stability. Basically a larger cavity gives better protection from frosts. A single layer acting as a curtain is all you would need to remove the risk of freeze burn. Don't forget the fact that you can manipulate bubble insulation as a ground fleece or cloche too
Bubble wrap is a great insulator in the container garden. More commonly thought of as a greenhouse insulator, it can be wrapped around patio pots to protect both the pot and the roots it contains from damaging frost action.
