To Slope or not to Slope.....that is the Question!
Hi Again!
Right Time to build my Poly-Carbonate Cover.
Pond is 6 Metre x 3 Metre.
Poly-Carb is 25mm clear.
Going to build a Frame to rest/attach sheets onto.
So....in your educated opinions..... which option would you go for:
Life would be easier to just use 3" x 2" timber all around and across......but that would mean the Poly-carb would be flat and water couldn't run off. Although the way I'm going to do it would mean that there would be accross water support so there shouldn't be a sag problem. And then I would have a neat, pretty draft-proof cover.
Or would you recommend trying to have a slope on the covers and maybe have 1 side 6" x 2" opposite to 2" x 2". This is going to take alot more work, trying to get a decent cut on the cross timbers and having them gradiented from 6" down to 2". If I get it right it....it should still be draft proof, but the cuts will have to be Very accurate and will cost more in timber.
What do you think?????
Cheers

I would just build it flat and lift one side up 6" and fill the gap around 3 sides with polycarb.
Thanks for the reply.
If I understand you correctly, I would then be using Polycarb triangles for the gap? That would mean I would need to buy additional: 2 x 3 metre strips and a 6 metre strip.......already spend over £400 on Poly-Carb, so have no money left to buy even more!

You would need 1 piece 3m x 450 mm to do it and cut it yoursel. Alternatively use ply. What you save on not buying 6 x 2 and then splitting it should cover the cost.
I'm having difficulty getting my head round this, from the information supplied.
Not sure how you intend to support this over a pool of that size.
Remember a "fall" of only 1" outwards from the centre is sufficient for the rain to run off.
So if you want to use 3 X 2", plane down each of the 3 metre lengths from the middle at 3" towards each end, finishing at say, 1.5", to create a "roof shape."
If you make it flat even using 3" X2" you may get a bit of a sag in the middle which would collect rainwater.

Hi Doghouse,
Nearly got it!! But instead of the roof shape, it would be one slope from the left to the right. So lets say looking at the pond it will be 6 inches high on the left and only 2 inches high on the right and the 4inch difference would therefore be spread over 3 metres.

Yep, that would be more than enough.
I was trying to think of a way where you didn't have to fill in one side with more polycarb, or whatever.
