Thought I would share this I found while surfing yesterday. I will be attempting to build this sometime soon.

I can't build that. All the measurements are metric!!

Sure you can! If you look at the top of the page again there is a button you push to convert it to imperial units.

Erlend, surely Bergen suffers a little more than slight frosts!

Oh, I did'nt notice that. Has anyone used that transparent corrugated plastic stuff that looks like a sheet of tin? How long does it last? I am going to build a shed in my back yard hopefully next year, and it will have a lean-to on each side. I was thinking of making one of them a green house by building it with the corrugated stuff.

Not really, usually we have temperatures above freezing. It can be 10 degrees celsius in both July and January. Compared to the rest of Norway, Bergen is a mild place. We had two or three extended freezes last year with a minimum of -7 degrees C.
Still, it's no tropical paradise either! ;-)

I am planning to install an extra heat-source so the space doesn't get below 5 degrees C. I would insulate the base, and add 50cm insulated walls at the base of the structure. I am thinking either heat-cables on the floor or a small space heater. And maybe replace the plastic-sheeting with translucent plastic windows.

-7C is not bad. Similar to here then (Suffolk, UK). I've just got hold of a greenhouse which was 21 feet long, and was being given away for free. All I had to do was dismantle it and pick it up. It came complete with internal fold-away staging as well. The only thing was that the door was bad, so I bought another greenhouse from a local shop which was a greenhouse but only 2 foot deep. I put that on the end without a door, and left out the back panel. So, I can use the door on the 'porch' greenhouse, and walk right through to the main part. Seems a bit odd, but works well. The 'porch' is currently holding a brugmansia that is flowering away like mad, and scenting the entrance, as well as a guava and a few cactus. I don't heat the greenhouse, but have bubble-wrapped it. The bananas are inside in their pots, and the most tender ones are also wrapped in fleece. All seems fine so far.

When they say to use UV resistant Polythene film, does that mean the plastic is resistant to UV or it won't allow UV to pass through it?

Mustang

Usually resistant to UV, ie it won't break down in a few months time.

I'd use corrugated panels... I think i've read that last from 10-20 years and thats probably if you had it out all year. That is awesome and looks very easy to build. I think if you had a miter saw and a nail gun (if you weren't taking it apart) or a drill and and driver, you could really build that fast. I've got a perfect spot for a small greenhouse behind the house (facing south), but i'd probably just use it for starting plants and for storing stuff. In winter it would be way to cold here to heat it.

-32C isn't uncommon here. We've already been down to -6 and its not even cold yet.

MediaHound

That looks just right for some

I just covered my back porch with a product from Palram called Palruf http://www.palram.com/HTMLs/product....2685&BSP=12650 and am pleased with the product. I installed the pearl for reduced light on my livingroom wall, but they have a clear also. About $27US per 2'x12' sheet from Home Despot.

They also have a greenhouse specific product that is like a honeycomb and is much stronger and stiffer than the corrugated panels and reduces condensate dripping http://www.palram.com/HTMLs/product....2519&BSP=12511

Regarding the plastic film over the framework, if the plastic isn't specially UV coated, it will start to disintegrate within a season and you'll have to recover it each year. I use black plastic as mulch on my garden each year, and I always need to replace it in Spring due to crumbling. I'm not sure if the coating blocks the UV, just makes the plastic last longer.

I could not find how much per sheet.
Can you tell me? I am very interested.

Hi Erlend,

I admit that it's a nice design, but my modest opinion says it'll not be that stormfree. I don't know about the storms in Norway but in Belgium we have some pretty storms from time to time; usually in the autumn and wintertime.
I always make my constructions more solid then they need to be. Winds of 120-130 km/u didn't move my construction the past winter one cm.
I think that the solidity of structure, has to be considered besides the insulation and the esthetics. After all, our bananatrees needs some nice, steady and leading hands, towards springtime.

Kind regards,
Gunther

Benny, I paid $27 US for 2' x 12' per corrugated sheet retail from Home Depot. They come in 8' lengths also. They did not stock the miltiwall sheets, but had lesser quality Palram corrugated sheets for $16 US without the UV coating. I installed them as a roof over my back patio just outside my livingroom. I do not have pricing for the multiwall sheets. I believe they are headquarted in the UK also.

Habor Freight keeps putting their 10' x 12' greenhouse on sale every 2-3 months for $599 just to tempt me! I figure this is cheaper than I would probably spend putting mine together, but I figure I want something larger eventually. I think I'd like something maybe 15' x 30' but doubt I would be satisfied with even that.

I bought the nonUV type sheets from Home Depot but they did not last 2 years and they are now disintegrating. They are very brittle and make lots of holes which are no longer useful. I noticed that they are made from Israel.

I will not encourage anyone to buy this because it is a waste of your hard earned cash.
What I am looking for is something that will last a lot longer.
I gogooled this thing but the cheapest was $64 per sheet but it is the shipping that will kill you.
I guess I will have to look within 100 miles in my area maybe I can get them cheaper.
Another alternative is the 4-season glass.

Benny,

If you are spraying copper sulfate, lime-sulfur or other sulfur based chemicals, those sheets would become brittle. If there are nearby grape vineyards or farms that spray fungicides, any plastic based covering of greenhouses will become brittle and easily disintegrate.

Joe:
You are right right and I will keep that in mind and take a note of it but I bought quiet a few of those and I also use them on the side of my house where I can store my junks and tools.
One thing I notice though is only those clear panels that became brittle the green ones still are pretty good.
I can only conclude that they are the cheapo kind. I should have bought the $27 per sheet. You can tell the difference when you touch them.
