Step of lathing for polycarbonate

Step of lathing for polycarbonate Step of the sheathing for cellular and monolithic polycarbonate

Among transparent roofing materials, such material is incredibly popular, like polycarbonate. It is chosen because of its high degree of strength and rigidity, resistance to low and high temperatures, and also due to its long service life. The key to success for each project is a correctly calculated step of the sheathing for polycarbonate.

Specifically, such an indicator makes it possible to save on consumables and create a durable and strong structure.

Requirements for polycarbonate lathing

Installation of the lathing for polycarbonate is determined by some requirements:

  • It is possible to safely disassemble the structure with low quality losses.

  • It is imperative to comply with building codes with competent observance of the parameters of sound insulation, waterproofing, thermal insulation and strength.
  • Organization of the ventilation system.
  • Sun penetration should have a softened brightness.
  • Compliance with the standards should create the required level of lighting.

Let's consider what parameters the crate pitch will depend on.


What may determine the pitch of the crate for polycarbonate

The dimensions of the crate for material such as polycarbonate will depend on on certain parameters that must be taken into account in order for the roofing system to effectively withstand snow loads and negative environmental factors. All developers strive to save on building materials, as well as to make a high quality building at low cost. There are several options to reduce financial costs during the construction of a certain structure - to make a rare base and use a material with a greater thickness or equip a crate with a private step and use thin sheets of polymer type. But to save money, developers are often faced with these negative consequences, such as structural damage under snow load. With this approach, you will need to spend 2 times more.

For this reason, when creating a purlin for profiled polycarbonate, it is necessary to take into account the following parameters:

  1. Step of lathing for polycarbonate A kind of structural design - sloped roof and arch.
  2. Geometric parameters of the structure, which include the width and length of the span, as well as the height of the arch.
  3. The strength characteristics of the framework are determined by the materials.
  4. When installing a timber structure, it is necessary to take into account the possibility of its deformation during use.
  5. When using metal profiles in the installation, welding is required, but such a structure will be much more durable than wood.

  6. The thickness of the coating will determine the ideal strength with greater thickness, but also the weight increases.
  7. The use of monolithic polycarbonate is superior in strength characteristics compared to honeycomb.

Geographic location should be considered with rainfall indicators.

Next, let's look at how to make calculations.

How to calculate a lathing for polycarbonate

In order to make a lathing for a canopy from a polycarbonate canvas, you can use:

  1. Pipes - you should choose for such purposes, products from rolled metal products of a honeycomb type with a cross section of 2 * 2 cm.

    If required, it is important to create an arched type of roof of a specific radius, and it is important to use a roller type machine for bending.

  2. Steel corners - bolts, corners, screws and special fasteners are required to assemble a steel frame. To avoid negative consequences in the future (deflection under snow load), the distance between the trusses should be no more than 1.5 meters.
  3. Components made of aluminum - in contrast to the frame made of steel, this type of construction has an undeniable advantage - they do not undergo corrosive changes.

    But its disadvantage is the high cost, almost 2.4 times more.

  4. Wood - in order to create a frame for polycarbonate sheets, glued wood should ideally be used. In this case, using simple boards and massive bars is not a rational decision, it will lead them, and this will provoke the appearance of cracks, cracks and deformation.

Please note that the installation work of polycarbonate sheets on the frame so that the stiffeners are at an angle of 90 degrees to the trusses.

The pitch of the lathing for monolithic polycarbonate

Polymer molded plastic is characterized by increased quality characteristics and the ability to resist mechanical damage due to its high degree of density. Usually, developers choose to create a transparent roofing panel with a thickness of 0.2 to 0.4 cm. For the installation of monolithic polycarbonate, it is required to make a frame with a step:

  • Up to 0.

    5 meters for arranging a pitched roof with sheets with 0.2 cm thick and arched - 0.7 meters.

  • 0. 8 and 1 meter, respectively, when using panels with a thickness of 0.

    3 cm.

  • 1. 2 and 1.5 meters when using sheets with a thickness of 0.4 cm.

If you are laying monolithic polymer type plastic with a thickness of 0.5 and 1 cm, then you need to follow manufacturer's instructions.

The pitch of the lathing for cellular polycarbonate

The cellular polymer is a popular building material due to its relatively low price and sufficient strength. When using it, it is permissible to manufacture a more rarefied type of frame if it is made from products in the form of metal. In order to perform the calculations correctly, it is required to take into account not only the types of construction, but also the width of the canvas, the thickness and length of the span, and also the region where the object will be built.

So, to create a high-strength frame, it is necessary to take into account the step under the polymer honeycomb plastic:

  1. Step of lathing for polycarbonate For lathing of polycarbonate in 0.4 cm (for arranging a greenhouse complex, structures of a temporary nature), it is required to install at a distance of 0.4 to 0.5 meters for pitched roofs and 0.6 meters for arched structures.

  2. For lathing for sheets with a thickness of 0. 6 cm, when creating canopies, awnings, greenhouses, you must adhere to a step of 0. 6-0. 7 meters and 0.7-0.

    9 meters respectively.

  3. For a polycarbonate lathing of 0.8 cm, which is quite often used when equipping winter-type greenhouses, carports and other objects, it is recommended to adhere to a step of 0.8-0. 9 meters for pitched roofs, and from 1 to 1.

    2 meters for arch roofs.

  4. For 1cm polycarbonate battens where excessive load on the structure is expected, consider step 1-1. 2 meters for arranging a pitched roof and up to 1.5 meters for an arched roof.

If you use polymer sheets with a thickness of more than 1 cm to create structures with a specific character, then the distance between the trusses in the crate should be calculated individually, and this is extremely important for high quality.

Recommendations and useful tips

In order to create a strong and durable structure from a translucent roofing material, you need not only to use material from trusted manufacturers, but also adhere to the recommended step for creating the lathing. It is also important to consider that when attaching a honeycomb type polymer, longitudinal honeycombs should be directed exclusively from top to bottom. Only with this arrangement of the panels will it be possible to create without obstacles a condensate shade that accumulates in the honeycomb when the day and night temperatures change. Otherwise, as a result of water stagnation, the presentable appearance of the material will deteriorate.


The pitch of the crate for cellular / monolithic polycarbonate is a rather important parameter that, if correctly calculated, guarantees positive results.

The lathing for honeycomb type and monolithic polycarbonate has its own differences, which are important to consider.
