L20 x W16 x H9 Greenhouse Structure. Please Help.
I have to construct L20 x W16 x H9 rooftop greenhouse. I have to take two things to consider at first.
1st is, it should survive outside temperature in summer that will be 45-48 at its peak. (keeping normal temp inside would not ba problem for me).
2nd is, it has to tolerate heavy wind blows & rains etc so it can standwith without any damage.
Anyhow, 1st i had decided to the structure by wood but it goes very coslty.
I am thinking for using
1-1/2 inch angle iron to use as main pillers for (vertical usage) &
1-1/4 inch angle iron to use vertically all the way around.
What do you guys suggest?
One more thing:
I am not using Polycarbonate Sheets for being expensive too.
I will use thick polythene rolls that will be in direct contact with angle frame.
The apprehension is that polythene sheet over angle iron frame may get damage or get melt due to heat of summer or hot angle itself.
What do you guys recommend what should i do? What should be the minimum thickness of polythene sheet i should use?
How should this polythese sheet should be affixed with angles.
Looking for help.
