Found this product ideal for my requirements, and service received was excellent.
Greenhouse insulation excellent, certainly more light than the one with smaller bubbles. As ever, delivery very quick.
Excellent service - arrived quickly and am currently putting it up in my greenhouse - easy to cut and fix with the appropriate clips for aluminium frames. Useful size to get the job done with fewest joins. So far it is keeping the frosty winds out.
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.

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
