In my previous article, “What is Greenhouse Polycarbonate” I discussed the physical characteristics of the material. In this article I will provide a brief overview of how to install a greenhouse polycarbonate.
Most people try to make it too difficult. There are only a few main points to ensure your polycarbonate is properly installed.
The biggest problem is to determine how many framing is needed to meet the burden of snow and wind in your area. Most people who sell polycarbonate for greenhouses will have a chart with suggested spaces for purlins. Another source for this information may be your local licensing office. Also, you must be able to get information about the right screw distance that will coincide with your frame space.
Multiwall polycarbonate sheets are flat on both sides. According to my previous article, you must use a sheet with UV protection on the one hand. When looking for bill of material you don’t look for “flip” sheets when cutting angles as you do with plywood or other similar material to save ingredients. If you do this, you will have a part with a UV layer on the wrong side. To install properly flutes or channels must run vertically. This so that each condensation that can be formed on the channel will be allowed to drain the bottom of the channel.
There are several components needed to install multiwall polycarbonate correctly. The first is the profile of H. It is used to hold the sheets with the side to side. There are several types of available. There is one part or two parts (base and hat). They are made of polycarbonate or aluminum. Both parts of H are more expensive as rules, but they are much easier to install on longer sheets, say more than 12 ‘long. To install one part H you have to loosely put your sheet on both sides that allow space for H. You then slide you up or down the sheets to the right location and then tighten the sheets. To install 2 parts H (aluminum or polycarbonate) the first time you mess up the base to your frame. You then put the sheets on both sides of the base. Next you will mess up or take a lid into place. sources from 291bet Usually polycarbonate h gasps and the aluminum lid will be chaotic to the base. H’s will be very tight and we usually don’t use sealants with them.
The next section is that you are sometimes called J. This happens at the top and bottom of the sheet. The purpose of this profile is to keep bugs, moisture and dirt out of the channel. U at the bottom of the sheet must have a small hole (1/8 “) approximately every 2’To allow drainage.
The next part is F profile. It’s used to do an angle. If this section is not available, we sometimes just put you on the edge of our sheets and slam it tightly together to make corners. Some manufacturers offer a ridge profile from polycarbonate.
When placing your sheet, you must allow adequate space to expand and contraction of sheets. Also, you have to drill a hole for your screw with a slightly larger drill than your screw to allow contraction and expansion. One of the most important parts to do is 1 “Wash neobonded around your screw. This will make you not have a leak around the screw. Be sure not to tighten your screw or your polycarbonate” dimples “.
