To get a high yield and protect your vegetables from the negative effects of fog and high humidity, you need to take care of the installation of the greenhouse. Often in the manufacture of greenhouses, gardeners use plastic wrap, but it needs annual replacement, which entails financial costs. We will tell how to make a greenhouse from polycarbonate, demonstrate all the pros and cons of this material.
This material is made in as two-layer sheets of plastic with different thicknesses. As a rule, sheets with a size of 6 * 2.1 m and a thickness of 4.5 mm are used.
Polycarbonate has a number of significant advantages in comparison with glass and plastic film:
To make the polycarbonate construction durable, you need to follow some requirements:
Care of the polycarbonate greenhouse
It is best to carry out the drawing of the greenhouse, as well as mark the place where it will be installed in the garden plot. Under the greenhouse you need a lot of free space away from trees and structures to provide good ventilation and plenty of light and heat.
In the drawing it is necessary to display what kind of greenhouse will be. Here there are several options:
If you chose a place, dimensions, shape, and there are necessary drawings, you can begin the arrangement of the foundation. For the greenhouse, the foundation is very important, and the strength of the structure depends on what quality it will be.
There must be holes for ventilation in the form of window and door openings. The roof should be made in the form of an arch, thereby increasing the volume of air in the structure. The built-in leverage system will allow you to open vents embedded in such a roof.
The pane size must be at least 1/4 of the entire roof surface. Additional air circulation will be provided by doors located in the end or side walls of the structure.
For paving, select paving slabs, and ridges enclose high curbs that will greatly facilitate the process of caring for plantings. Secure the rods under the ceiling space, which will be needed to secure some plants.
Size of the greenhouse from polycarbonate
The first step is to lay the foundation in parallel with which fences for ridges are poured. For the frame, it is better to use square pipes or metal corners. At first make a binding, and then fix it on the base.
The metal structure must be carefully painted before installation, otherwise it will succumb to corrosion.
The strapping is fixed on the foundation with anchor bolts.
Drawing of the foundation for the greenhouse
The bar-like foundation is made of wooden bars. It is financially inexpensive, but it will not last long, up to a maximum of 5 years, despite being treated with an antiseptic. In time, the tree will start to rot. Installation of log-like basement is as follows:
The brick foundation is distinguished by its quality and service life. If it is right to build such a foundation, then it can serve for a long time, but it will take a lot of brick to make it to support the weight of the greenhouse. First, a cushion is made with waterproofing to protect against the destructive action of moisture from the soil. In the construction of the brick foundation used conventional cement-sand mortar.
In order to make the foundation of a brick more sustainable, it must be plastered.
A stone foundation is also suitable, since such a foundation is durable and designed for any loads.
It should be borne in mind that laying a natural stone of unequal shape requires certain skills, and independently making a stone foundation is not an easy task. It is best for the solution to use clay mixture in a ratio of 1 * 1. Such a solution will contribute to heat saving. So that the clay is not washed out with water, the foundation should be plastered, and if it turned out too uneven, then put the formwork and pour concrete on the edges.
The advantages of the strip foundation are that the funds, as well as the time and effort spent, are relatively small, but the result is excellent. This type of foundation is different from other durability and reliability. In its manufacture you will need:
The strip footing is as follows:
This technology will ensure the high strength of this foundation.
Any of these bases should be set up at a distance of 25-30 cm from the ground level. This will protect the foundation from destruction, and the construction will last a long time.
Bar-shaped base for the greenhouse
Installation of frame
An important role is played by a correctly assembled frame made of reliable materials, one of which is a profile. We will not elaborate on the factory constructions from the profile, as in the purchased kit you will find detailed assembly instructions. Let us dwell on a more economical option - the frame of the profile for drywall. The design with rounded shapes will not work, but the frame will be strong enough to withstand snow and wind loads.
Consider the advantages of using such a material for the manufacture of the frame:
Framework from the profile
First you need to make a drawing or at least draw a future sketch greenhouses with dimensions. After that, using the resulting data, cut the workpiece. Now to the foundation with anchors you need to fix the profile, which will serve as the basis of the whole structure. After that, you can proceed to the installation of the frame.
Drawing of the greenhouse frame from the profile
As for the assembly of the frame, everyone decides to do so he is comfortable. We recommend that you assemble the arches on a horizontal flat surface, and then mount and trim. How to fix the sheets already written in the article.
Assembly of the frame
Framework for the greenhouse can be make of several types of pipes. If the frame is metal, it is better to use shaped pipes, welding them with electric welding. The arched structure suffers less snow loads, but in order to give the pipe a shape, you need to use a pipe bender. If there is no desire to bend pipes or buy ready-made arches, then you can make the shape of the greenhouse the same as that of a metal profile - with a sloping roof.
Racks are attached to corners and walls of the trim by welding. At the same time, mounted doorways. On top of the pillars and door construction is made upper trim, which are attached to the arch. After that, proceed to the installation of arched window vents on the roof and fixing the hinges to the ridge. Build a lever system for lifting window vents, then proceed to paint the frame.
Frame of the future greenhouse
It is undesirable to make the frame of the greenhouse from round pipes, because screwing the polycarbonate, the screw may slip to the side and damage the sheet.

You can quickly assemble a simple frame from polypropylene pipes. Again, you need to make a drawing and cut the workpiece. To assemble the frame, you will need a soldering iron, and a certain number of pipes and fittings will need to be purchased in accordance with the chosen shape of the greenhouse.
One of the advantages of a polypropylene tube frame is the perfect combination of strength and flexibility of this material. Flexibility allows you to give the frame the desired shape, and, strength allows you to withstand considerable loads.
Manufacturing a frame from plastic pipes
For convenience, you can make a ventilation window in the door. Once the frame is assembled and fixed, it can be sheathed with polycarbonate.
Now it is important to take care of the insulation and the greenhouse heating system. Modern technologies involve the use of transparent or bubble plastic for warming the greenhouse inside and out. The advantage of this solution is that this material does not absorb sunlight and looks decent.
Heating in the greenhouse may not be entirely cost-effective, but, as the saying goes, the goal, and in our case to collect a rich harvest, justifies the means.
Heating a greenhouse
Sheets of material are laid strictly according to length, fix them with screws, or special shims. They securely fasten the polycarbonate to the arch of the frame and save it from deformation during expansion in the winter. The role of the pressure plate will play corners for plastic arch, which you can buy in the store building materials.
Before starting the installation, it is necessary to rid the polycarbonate of the packaging film, smear the edges with glue and fix the plastic corner. Open edges of the material are treated with scotch tape or sealed tape, and the bottom edge with perforation will provide the desired drainage effect.
Types of fasteners for assembling the greenhouse
To connect two sheets of polycarbonate with each other use the intended connecting bar. Then you can proceed to the mounting of polycarbonate sheets on the frame of the greenhouse.
Initially, the roof is sheathed with polycarbonate sheets, and only then the remaining part of the arch from the ends. Further, the walls and doors of the structure are finished with the material. Connections at the corners are closed with metal or plastic corners. After that, remove the remains of the protective film.
The finishing touches can be considered the installation of fittings, handles, gate valves and fixing hooks on the door, as well as a rubber seal on the air vents for complete sealing.
Even if you, having no experience, you will be forced to entrust some of the work to professionals, more volume will fall on your shoulders. Therefore, try to approach the process with full responsibility to continue to enjoy natural products grown in the greenhouse.
