Bubble Wrap Insulation for greenhouse - where to buy?

Are you after UV Stabilised, or "quick-rot" ?

 

I used to get it from work
Along with something called "Correx" or "Cordex", and some PVC tape.

Great for building one winter protection outside on nanas, just build a ring around a few sticks, stuff it with straw and hold it in position with the pvc tape, works a treat.

 

Elixir Garden Supplies on eBay maybe? I've bought quite a bit from them over the years. Quick delivery, products have been OK etc etc.

30M x 1.5M = £44.99 (inc postage) - i.e. £1 per sq.m.

Curious to know how you are going to tape it up ??

 

I think if it is not taped there will be too much air movement between the glass-side and the plant-side?

I know the norm is to use spacers to stand-off the bubblewrap from the glass, but I wonder if a "curtain" approach would be better (and would be more akin to what is done in commercial greenhouses).

Horizontal wires at eaves height (probably a bit higher so you can physically stand in there!) so maybe a wire end-to-end along the middle of the house, under the ridge, at the lowest height that you can stand under, then a wire end-to-end just below the eaves, and then drape the bubble wrap over it so that it hangs down the sides too, taped/joined into a single piece. Probably needs to be taped to the frame along the bottom (in a way that can be un-taped in spring), to stop glass-side cold air falling "under" the curtain. Then you can remove the whole one-piece curtain in Spring.

In a commercial greenhouse they would "draw" back the flat false ceiling curtain, and I suppose it may not even be transparent as it would be more important that it was a good insulator - they re-heat the space above the curtain in the morning, once warm enough they open the "curtain" so the plants get light, as normal, and then close the curtain again in the evening to reduce the volume of air to heat.

 

P.S. What you are you trying to look after? I am increasingly of the opinion that it is easier, and possibly cheaper, to construct a very well insulated "room" in a garage, and provide some artificial light. For exotics that may only need to be "tick over" light, for dahlias it can be "No light" of course

probably with greenhouse, over winter, is that the light (from Sun) is rubbish, compared to Summer, and in a lousy Spring like 2013 everything is on the drag. With artificial light you can bypass that problem.

 

Blimey! That sounds like a major project. Let me guess: lots of Boys Toys involved?

 

I got some from Arco....600mm x 75 mtrs...£26.40 inc vat....big bubbles....i ideally wanted the wider rolls and the small bubbles but it wasn't in stock and i couldn't wait
Work in progress....
