Insulating a greenhouse for winter?

[lulubell]

Hi there was wondering if there is anyway of insulating my greenhouse over winter without using a heater? Thanks xx

bubblewrap!

Thanks Chris didnt think of that

I agree with Chris (for once!) You can buy those plastic clips that slot into the frame, push the bubble wrap on and push on a securing thingy that comes with the clip. Buy the Bubble wrap from the roll at garden centres. It lasts for years!

Those push-in grip thingies don't fit tight in my greenhouse. I keep going out to find they've popped out and the wrap is all 'nicely' draped over the plants

Has anybody got any better ideas?

Make sure the plastic clips are fully through the bubblewrap before you put the clip in the groove. Also cut 6" lengths of cane and fit between the glazing and the frame if that makes sense.

I don't like the green ones (they seem too flimsy) - I use something like this ALM Greenhouse GH009 Shading & Insulation Fixers x 20 | eBay
Had them years so I've no idea what make they are!

I do make sure BM, but they're hopeless - I'm using all my clothes pegs atm

Those ones look a bit more like it VC they're worth a punt anyway

How to insulate a GH my way!
Run a wire along the eaves, front to back of the GH
Cut the bubble wrap so that it will run from the base on one side, up and across the roof and back down the other side.
Put the plastic thingys in the grooves and give them a good twist to lock them.
Thread the end of the bubble wrap over the wire and pull it down to touch the floor on both sides. (I also have wires at the top of the side walls to hold the BW back)
Push it onto the plastic thingy spikes and push the retaining clips, over the top. If you make a hole in the BW, it makes it easier to put it in the right place next year.
Each panel of BW will overlap its neighbour so its easier to put all the BWs up and pushed onto the spikes before you put the retainers on.
You'll need to adjust the lengths where there is a window!
Buy more clips than you think you'll need as you'll always lose some!

Don't forget your 50p seeds while you're there!

I also have some polystyrene insulation sheets which are about the same width as the first panel of glass. I have a row of these along the bottom sections and then trap the bottom of the bubble wrap behind them. Also stand pots on insulation too, every little helps and I really don't like using a heater.

None left in her local store, VC. I emptied the lot!

That's greedy, Chris
