I get a great deal of concerns about how to determine the polycarbonate sheets and profiles needed to create a greenhouse. I have discovered that the very best way to manage this is to break the venture down into sections. You would determine each and every area and then include them all jointly to get your final bill of material. I will display you an case in point of how I would determine a twelve x 24 greenhouse with 6′ sidewalls and a 8′ peak peak. Your roof panels will be 6′ six”. This give you slightly significantly less than a 3″ overhang on the roof panels. The profiles arrive in the pursuing lengths.
H profile (connecting sheets aspect by aspect) 12′ or 24′
R profile (ridge profile) 12′ or 24′
U profile (this caps off the channels of the sheets, utilised on the tops and bottoms of the sheets) 12′
F profile (for corners or flashing) 12′ or 24′
I would figure a single side and then multiply it by two.
Every aspect would have six sheets at a 4′ width by 6′ six”.
When you are figuring the H’s (sheet connectors facet by facet) you just subtract 1 from the complete variety of sheets on every aspect. So, for this example, you would require five H’s at 7′. You would want to purchase five H’s at 12′, as this is the duration they are offered in. You do not want to use a “patched with each other” H on your roof (or at any time actually).
If you are utilizing a polycarbonate R or ridge, you would need one piece at 24′.
To determine the U’s you would need to have to figure the linear foot overall for the bottom and tops of the sheets. แผ่นพลาสติก pvc to this is if you are using a ridge. The ridge is already serving the very same objective as the U at the top of the sheet. So, given that we are employing the ridge we want 24′ of U, or 2 items at 12′.
Multiply this by two and you are done.
I would determine one particular facet and then multiply it by two.
Every single side would have 6 sheets at 4′ x 6′.
When you are figuring the H’s (sheet connectors facet by facet) you merely subtract 1 from the complete amount of sheets on every side. So, for this case in point, you would want 5 H’s at 7′. You would want to order 5 H’s at 12′, as this is the size they are obtainable in.
To determine the U’s you would require to figure the linear foot complete for the base and tops of the sheets. So, for 6 sheets 4′ vast you would need to have 24′ at the top and 24′ at the base for a complete of four – 12′ U profiles.
Multiply this by 2 and you are carried out.
I would just go ahead and determine the corners below. You want 4 F profiles at 6′. I would get one 24′ F profile for the total work.
I would figure a single facet and then multiply by 2.
You want to have a single sheet the whole size from the ridge to the ground. You will have to minimize the angle on site. So, I would purchase three sheets at 4′ x 8′.
When you are figuring the H’s (sheet connectors aspect by aspect) you just subtract one from the complete quantity of sheets on each side. So, for this illustration, you would require 2 H’s at 8′. You would want to purchase 2 H’s at 12′, as this is the duration they are accessible in.
To figure the U’s you would require to figure the linear foot complete for the bottom and tops of the sheets. So, for 3 sheets at 4′ you would want one 12′ U for the bottom. You also want a U for the gables. You know your roof panels are 6′ 6″, so this would be the approximate size of U you would need to protect the gable ends. So, I would get two of the 12′ U’s for the gables. This end would want a total of 3 – 12′ U’s. You are likely to have a doorway on a single stop, and will need to change this for the other finish. You will want to lower down on your sheets and also be positive to insert sufficient U to frame out your door exactly where you have reduce the polycarbonate sheets.
