Build Your individual Greenhouse – How to Determine The number of Polycarbonate Sheets and Profiles I Need?

I get many questions about the way to figure the polycarbonate sheets and profiles necessary to develop a greenhouse. I have found that The obvious way to tackle this is to break the job down into sections. You’ll figure each portion and afterwards incorporate them all collectively to Obtain your last Monthly bill of material. I will demonstrate an illustration of how I’d personally figure a 12 x 24 greenhouse with six’ sidewalls plus a 8′ peak height. Your roof panels are going to be 6′ 6″. This Supply you with somewhat a lot less than a three” overhang to the roof panels. The profiles can be found in the next lengths.

H profile (connecting sheets facet by facet) twelve’ or 24′

R profile (ridge profile) 12′ or 24′

U profile (this caps off the channels with the sheets, used to the tops and bottoms on the sheets) twelve’

File profile (for corners or flashing) twelve’ or 24′


I’d determine one facet and after that multiply it by 2.

Either side would’ve six sheets in a four’ width by six’ 6″.

If you find yourself figuring the H’s (sheet connectors side by side) you just subtract 1 from the overall range of sheets on each side. So, for this example, you Polycarbonatscheiben would need five H’s at 7′. You’ll desire to buy 5 H’s at twelve’, as this is the length they can be found in. You don’t choose to use a “patched together” H on the roof (or at any time actually).

Should you be employing a polycarbonate R or ridge, you would need one piece at 24′.

To figure the U’s you would want to figure the linear foot total for the bottom and tops from the sheets. The exception to This is often When you are employing a ridge. The ridge is previously serving a similar goal as the U at the very best from the sheet. So, given that we have been using the ridge we need 24′ of U, or two pieces at twelve’.

Multiply this by 2 so you are done.

Aspect Partitions

I would figure 1 side and then multiply it by two.

Either side would have six sheets at 4′ x six’.

When you find yourself figuring the H’s (sheet connectors aspect by aspect) you simply subtract one from the whole range of sheets on all sides. So, for this example, you would wish 5 H’s at seven’. You’d probably wish to purchase five H’s at 12′, as This can be the duration they are available in.

To figure the U’s you would want to determine the linear foot overall for the bottom and tops from the sheets. So, for six sheets four’ vast you would need 24′ at the highest and 24′ at The underside for a complete of four – twelve’ U profiles.
