I have been checking Coroplast out online as I was trying to understand how Corrugated Plastic could be used for coldframes.

Some sites says Coropast will not withstand the UV factor and does not have a long life.

However, I did find this site helpful in comparing different material:

My obvious, How long do you need it to last for? Even if you replace it every 3 years, at these prices it sure don't break the bank like Polycarbonate does.
Mine is standing up to the heavy snows we're getting, still looks good.
No contest versus glass etc.

True, but when you take in the factor of afixing it to frames each time, plus the disposal of it after only 3 years, I would rather have something that lasts a bit longer.

I have to have something ready soon, March is right around the corner.

Timely post, here, as two of my "roof" panels broke last week, either due to snow load or that fierce wind, or both,, so, will check out HD's supplies of what I could use as a replacement, but, agree with Betty,,lots of work for something that may only last a few years.

Will also try to find the manufacturer of the original GH, and see if they sell the panels separately.

Took a walk round today. Lots of snow, can hardly see where it all is. The roof covering is holding up well, no sags or droops, apart from me, having to keep digging out.
Dug out the door and the inside temp, in full sun was 79F, warmer than in the house!
Even saw a wisp of steam from the compost pile, snow all melted off the top.
More snow tonight.
Roll on spring, getting cabin fever.

Great job you did! You have got us started on the same idea. Like Smitty though, I wonder how hard it is going to do for central Alberta winters? Looks like all your hard work is paying off.

I could swear There was a post from someone in Alberta asking questions regarding my methods, but it seems to have disappeared, anyone else missing posts?
I firmly believe I have stumbled on something here with this covering.
I have since installed an air probe thermostat with a small heater and even at -26C I still managed to maintain 40-45F all night, this is ideal for seedlings. It would appear that there is some insulation benefits as the heater is not 'on' all the time, but fluctuates on the thermostat.

What a fantastic greenhouse and so simple to make. Thank you for the instructions. This may be something I may tackle this summer too. Yet another project. :roll:

After a hard winter it's still in good condition, will be firing it up soon. Already have cucumbers, melons and tomato plants ready to set out. Hopefully this year will get early tomatos, rather than waiting till August before they're ready.
