polycarbonate Which is best used for shelter
transparent and colored plastics are widely used in construction for the production of envelopes.For a reasonable answer to the question what is best for polycarbonate canopy is necessary to understand its properties and characteristics.Manufacturers offer two types of panels: monolithic honeycomb and different thicknesses and colors.Produced from the same raw materials, they have a lot of differences.
- Polycarbonate or solid: comparative characteristic
- optimum thickness polycarbonate canopy
- Principles color matching polycarbonate canopy
Polycarbonate ormonolithic: comparative characteristic
choice of the type of plastic is determined by several factors and, above all, the requirements of the coating material to the particular design of the canopy.The properties of the polycarbonate are directly dependent on the structure: honeycomb panel hollow and have a smaller specific gravity than monolithic.Accordingly, the price
Polycarbonate different color.
most important criterion for selecting the type of polycarbonate is its decorative properties.If stylistic solution requires the use of the material is similar in sight lime glass, it is necessary to give preference to a solid sheet.This material allows the creation of the original design, including complex shapes.In addition to the transparent panel has a large selection of the most dyed in different colors.
canopy from polycarbonate.
functional and practical canopy without any frills design made of polycarbonate.Light weight panels allows maximum ease the supporting frame, provided that the necessary strength and stability.In the manufacture of power systems for such a steel canopy profile smaller cross-section, which gives considerable savings.
canopy of reinforced polycarbonate.
choice between cellular or solid polycarbonate depends on its properties and characteristics.In the manufacture of awnings conventionally used sheet thickness greater than 6 mm, for the convenience of comparison, the table shows the parameters for such different types of panels.For the analysis of selected properties that determine the performance of the canopy:
|Features||Unit.Meas.||Types of polycarbonate|
|sheet width standard||mm||2100||2050|
|length panels||mm||6,000 and 12,000||3050|
|share||weight of the panel kg / m2||1,3||7,2|
|minimum bending radius panel||m||1,05||0,9|
|Light transmission coefficient||%||82||85|
|thermal resistance m2 ° C / W||0,28||0,2|
comparing parameters polycarbonateIt demonstrates that polycarbonate is almost six times lighter than solid.But the last 2.5 times longer than its competitor for durability.For other characteristics differences were not significant.When selecting the type of the panel are taken into account other factors: economic and ornamental, as well as the geometric dimensions and destination canopy.
Such structures are usually built to overlap include:
- balconies or terraces;
- parking public transport;
- visors and transitions between buildings.
One of the major characteristics of the panel is resistant to mechanical stress.In this regard, polycarbonate loses much monolithic.Vandal-proof properties of the latter make it possible to use it in public places, where the probability of intentional damage to buildings is high enough.
optimum thickness for polycarbonate canopy
Specifications and cellular and solid panels depends on several factors.To address the issue of a polycarbonate canopy is better to choose, it is first necessary to determine the optimum thickness to its specific design.Regulatory documents in the construction SNIP 21-01-97 and SNIP II-3-79 provide guidance on the application of this type of finishing materials.
how to determine the thickness of the sheets of polycarbonate
In determining the optimal thickness is taken into account and the appointment of polycarbonate canopy, and the level of loads on the structure.If we consider the polycarbonate, it is possible to make the following recommendations:
- 4mm panels can be used for relatively small structures with a significant radius of curvature, usually a polycarbonate is used for greenhouses and small canopies.
- Sheets polycarbonate thickness of 6 and 8 mm are used to cover installations subject to significant wind and snow loads, it can be carports or pools.
- panel thickness of 10 mm or more devices suitable for awnings, which are subject to extreme climatic and mechanical environmental effects.
structure of internal stiffeners have a significant impact on the strength characteristics of the panel.This fact should be considered when determining the optimal thickness of the sheet and the design features a canopy.The dependence of the sheet thickness polycarbonate, the size of the cell crates for shelter, is shown in the chart below:
Snow load on the structure is calculated taking into account the requirements of SNIP 2.01.07-85 for a particular climatic region of the country.For polycarbonate sheets is set still and the internal structure of the sheet for panels 16 mm or more.Such sheets may be of three- and five-layer cell with a rectangular or triangular shape.
how to determine the thickness of the solid polycarbonate sheets
Depending on the purpose of the canopy, used for its manufacture solid polycarbonate sheets with a thickness of 2 to 12 mm.This material is more durable than polycarbonate.For automotive visors and awnings are usually used polycarbonate thickness of 4 - 6 mm, because the thickness of such material is able to guarantee the reliability of the design in the different seasons.
Principles color matching polycarbonate canopy
architectural elements and building structures are perceived by others as part of an ensemble.When deciding on the choice of color polycarbonate canopy is taken into account the general background and the color of neighboring buildings nm.Especially popular among the population are blue, green, dairy and bronze panels.They are less likely distort the true colors of objects under them.When using such colors as red, orange and yellow should take into account the fact that all objects located under a canopy, covered by any of these materials will have an appropriate shade.
example of using polycarbonate red and changing colors of objects under them.
Apart from the usual panels, there are also translucent and opaque sheets are completely black or silver.The use of such panels is appropriate for awnings, which should provide maximum shading of the interior space.Typically, the color tone of the canopy is chosen for painting the roofing material of the roof of the main building, however, and contrasting solutions also have the right to exist.
When designing protective and decorative designs based on many factors.In deciding how to choose polycarbonate canopy to be determined, first of all, the type of material, its thickness and color.Cell panels are applicable for private construction and erection of structures, inaccessible to humans.Monolithic polycarbonate is used for vandal-proof buildings and other architectural elements of the original species.
