How to choose the right polycarbonate

Greenhouses and hotbeds are present in almost every summer cottage, allowing you to grow a wide variety of fruits and vegetables. However, for the construction of a greenhouse, you need to choose the right material: the film turns out to be too short-lived and quickly deteriorates, the glass does not retain heat very well and, moreover, is too fragile. The best option is polycarbonate sheets: this is a polymer material, equal in translucency to glass, but at the same time much more durable and convenient. How thick should polycarbonate be for a greenhouse?

Polycarbonate canopy supports

Particular attention should be paid to the choice of the support structure for the "light" roof. A gust of wind that seems to be not a hurricane force creates a pressure drop that can tear off a roof with an area of ​​ten or even twenty square meters. Lightweight materials are usually not very strong.

Accordingly, such materials require serious attention to their attachment to the supports. It is very important to consider at what distance the supporting structures of the roof are installed, as well as how this covering is fixed. Unfortunately, standard "press washers" are plastic pads for ordinary self-tapping screws - not always

can ensure the reliability of the roof attachment. In our climatic conditions, it is necessary to ensure a more reliable fastening of the coating. For example, you can do this using an aluminum profile (Fig. 1, 5). Do not forget about the standard elements for polycarbonate, such as start-finish profiles, docking "H" and corner joints. These elements ensure the tightness of both the material itself and the horizontal and inclined roof as a whole.

But we must also remember that cellular polycarbonate can be of different strength characteristics and different thicknesses, as mentioned above. Accordingly, the strength and price of such materials vary greatly. If you do not use a start-finish profile or perforated tape, then the polycarbonate can be filled with water, and even worse, this liquid can bloom, which will ruin the beauty of the translucent roof.

In addition, it must be borne in mind that when installing polycarbonate structures, a special sealant is used, which has increased adhesion to this particular material and does not harm it.

Note that structures made of cellular polycarbonate can be of almost any shape - domed, flat - and practically of any kind, because this material is easily machined, bends, which makes it possible to construct original structures from it. Thus, the form and appearance of the structure that is being erected depend only on imagination and the ability to place it on the site, gaining almost complete freedom for creativity.

Which color should you choose?

No less important is the question of choosing the color of the material, which is associated with the degree of transmission of light and heat into the room closed by this material.

The most popular and in demand are transparent and smoky colors. Colored material has a light transmittance in the range of 30-60%. Darker polymer colors transmit less light than lighter colors. This makes it possible to regulate the level of illumination in the room, creating a comfortable environment for relaxation.

If the structure is a small-sized visor with a small bending radius, then strong pressure of precipitation on the surface of the visor is excluded. Therefore, it is sufficient to use a 4-6 mm thick polycarbonate sheet. It is better to use such building material for protective canopies above the porch, above the fence gate, using a frame made of metal trusses (Fig. 5).

Polycarbonate sheets with a thickness of 6-8 mm can withstand snow cover up to 10-12 cm. But you need to clean the snow from the roofs as needed. Polycarbonate of this thickness is used for greenhouses, arched passages and sheds (Fig. 7, 8). For an area with a harsh climate, it is preferable to use a more durable material: a thin sheet of polycarbonate under the influence of low temperatures, gusts of wind and pressure accumulated on the surface of atmospheric precipitation can deform (sag) up to the formation of cracks, which can be observed over the past several years on the example of greenhouses in summer cottages. The greenhouses are covered with 4mm polycarbonate and the snow is not peeled off in winter.

Polycarbonate with a thickness of over 10 mm has high strength and shockproof properties. For example, polycarbonate sheets with a thickness of 16 mm can already be used in industrial buildings - for the manufacture of lightweight roofs of large areas that are subject to heavy loads. In winter, roofs made of such material must also be periodically cleaned so that the snow cover does not exceed 50 cm.

For each metal structure, sheets are selected taking into account the available area of ​​the structure and possible loads. The spacing of the longitudinal bearing supports of the frame should be no more than 700 mm. As for the spacing between the cross members, it should be calculated depending on the angle of inclination of the structure and the thickness of the selected material. With a polycarbonate thickness of 8-16 mm, the step should be no more than 1 m, if the thickness is less than 8 mm, then the step is less than 70 cm.

And the last thing that is important to know about: when attaching sheets of cellular polycarbonate, the hole for the fastening screw should be several millimeters (2-4 mm) larger than the diameter of the screw itself. In this case, the ability to control the thermal change of the material is provided. The hole should be at least 40 mm from the edge of the panel (fig. 5).

Place to place a canopy

The width of the space for one car should be at least 3 meters, and the length - 6 m. The smaller area does not allow a person to hide from sunlight or rain when repairing a car. Usually, the shelter is installed near the entrance to a suburban area or equips it next to the house and outbuildings under the same roof with them.

With this arrangement, it is easy to supply electricity to the carport. Some owners even make motion-sensor-equipped lighting. They also provide for the presence of a storm drain or drainage ditch nearby. For safety, the site is arranged away from open fire, barbecue.

Polycarbonate porch canopy. Photos and design features

In order to independently equip the visor above the polycarbonate entrance, you must first of all create a good sketch, in which all the details of the structure are reflected in detail.

In terms of light transmission, polycarbonate can compete with glass

When installing a polycarbonate visor over the porch, you need to take into account that its main function is to take on snow, water and dirt, protecting the entrance to the house. This means that the best shape of this building element is arched. Such a canopy will allow precipitation not to accumulate on the roof, but to easily slide to the ground.

A visor over the porch will protect the entrance to the house from rain and snow

Having decided on the shape of the polycarbonate visor over the porch, it is necessary to mount the frame and cut out the canopy elements, not forgetting the overhang length of at least 80 cm. The parts are attached to each other either with nuts and bolts, or are welded by electric welding. You can buy a ready-made prefabricated polycarbonate canopy, which already has the necessary holes in the base fittings.

Cutting of polycarbonate sheets is carried out on a protective film with a clerical knife. If the width of the panels is more than 8 mm, they can be cut with a circular saw with fine teeth. Installation of polycarbonate panels is carried out with a protective film outside, since it is this layer that is protected from UV radiation. After assembling the entire structure, the protective film is removed.

The last element of the installation is to protect the open areas of the ends of the polycarbonate plates from dust, water and dirt. For this, a special aluminum tape is used, which is installed on the ends of the panels (as shown in the photo).

Structural elements of the visor made of cellular polycarbonate

Being an excellent alternative to expensive glass, metal or wood - traditional materials for the manufacture of awnings and canopies, synthetic polycarbonate has a number of advantages over them, which made it so popular. A variety of color palettes, ease and ease of installation allow the most daring design fantasies to come true.

Canopy design and assembly

Before purchasing materials and assembling, it is imperative to draw up a project and a drawing of the future canopy. How to calculate the parameters and choose a visor model? It's simple - start from the height, dimensions of the porch.

  • a canopy depth of 80 cm is sufficient for the canopy
  • the width of the structure should be 50 cm wider than the width of the porch to protect the site from precipitation
  • a canopy on supports (racks) looks harmoniously on a high, spacious porch for 5 or more steps
  • if the porch is miniature (23 steps), it is better to do with a frameless structure on brackets.

Canopy on metal supports

Using the example of instructions and a photo, we will consider how to make a polycarbonate canopy over a porch with supports made of metal pipes with our own hands.

Required materials and tools:

  • polycarbonate sheets of the desired shade, thickness 6-8 mm
  • square metal pipes (width 5 mm)
  • fasteners for polycarbonate
  • anchor bolts
  • welding machine
  • building level
  • screwdriver
  • pencil / marker
  • roulette.

Stage-by-stage manufacturing of the structure:

  1. The place for installing the visor must be cleaned of debris and leveled.
  2. We prepare recesses for pipes: on the sides of the porch, you need to dig square holes 1 m deep, up to 40 cm wide.A 20 cm thick layer of sand should be laid on the bottom and compacted.
  3. On the wall of the building at the entrance, it is necessary to make markings according to the parameters of the future frame.
  4. Using a welding machine, you need to assemble a metal frame. Further, the joints are sanded, the frame is covered with a primer and a layer of colored paint.
  5. The supports must be installed in recesses, poured with concrete mortar and wait until they dry completely.
  6. The frame is attached to the walls of the building with anchor bolts.
  7. At the top of the frame, you need to install a crate. In the simplest version of a straight or lean-to canopy, metal pipes do not need to be bent and rounded. It is important to respect the angle of the slope.
  8. On the pipes, in the places where the sheets are attached, holes must be drilled. Their diameter should be 2 mm larger than that of the screws.
  9. Screw the sheets to the frame. For fastening, use large washers (gaskets) made of rubber or plastic to prevent contact of polycarbonate with metal.

Polycarbonate fastening technology.

[stextbox Polycarbonate tends to expand and contract when exposed to temperatures. Therefore, when assembling the structure, it is imperative (!) To leave a gap of 5 mm, otherwise the structure may swell / break from tension. [/ Stextbox]

If the structure consists of several honeycomb sheets, it is necessary to use a special H-shaped profile (connecting), into the cells of which the sheets are inserted. Also, a special end profile must be used to cover the side cuts of the sheets to prevent debris and dust from entering them.

Docking and end profiles.

As a result of the work done, you should get an approximately similar structure, as in the photo.

The wooden frame is made from a bar in a similar way.

Another option for a canopy on support pillars:

Canopy without supports (no welding)

As we indicated earlier, a small porch canopy can be made without the use of welding and supports. Rivets will act as fasteners, and metal corners for structural rigidity. The photo below shows a variant of the drawing of a simple canopy.

  • metal corners
  • rivets
  • riveting gun
  • a hammer
  • electric drill with a drill of the same diameter as rivets
  • profile pipe 20 * 20 mm.

It is very simple to make such a canopy:

  1. Prepare the profile - cut it into 2 pieces equal to the width of the canopy. Next, cut three more segments equal to the length of the canopy (taking into account the bend).
  2. The transverse ones need to be bent. This can be done using any rounded object with a suitable diameter.
  3. Drill holes in the attachment points of the parts.
  4. Using the corners, fasten all the parts with rivets.
  5. You need to attach polycarbonate sheets according to the same principle as in the previous method.

To better understand the principle of making such a frame, watch the video clip:

Miniature frames on brackets can be very beautiful, neat and graceful, especially if they are complemented by small forged curls.

This canopy is made according to the same principle as the previous one, but consists of several sheets of polycarbonate.

A canopy of several sections.

The following example shows a very simple curved visor on metal profiles with blue opaque polycarbonate.

The simplest canopy design.

The next canopy, although it has a very simple design and small size, looks very picturesque thanks to the forged curls.

Thus, using the example of two instructions with a photo, we showed how you can make a polycarbonate canopy over the porch with your own hands. This design is distinguished by simplicity and speed of manufacture, low cost, and, importantly, aesthetic appearance.
