PVC sheet - Ottoman design

Endoplas BTJ generally consists of PVC/UPVC and ASA.

PVC or Polyvinyl Chloride is considered one of the most precious products of the petrochemical industry and is used in various industries. In recent years, with the advancement of knowledge and technology, this product is replacing most of the traditional building materials such as cement, clay and... is

BTJ Endoplas products are generally composed of PVC and additives for product strength and its coating of the strongest UV, called ASA, is combined with granular paint and melted with an extruder and injected layer on PVC sheet.

ASA, which forms the outer coating of the sheets, is a type of strong anti-UV against the sun's rays to protect the color and the product itself. This resin is a type of engineered resin that is the result of research by the world's most prestigious laboratories.

One of the remarkable features of this coating is its high durability and increased resistance in adverse weather conditions, lack of abrasion and corrosion by chemical factors (such as salt, base, acid, etc.), its insulation against heat, cold and humidity. cited .

In old materials, things such as heavy weight, lack of color resistance to sunlight and high repair and maintenance costs, the need to use thermal insulation under the covers, rust, etc. are the main disadvantages that the progress of science and The proof of the characteristics of PVC sheets made us take into account the disadvantages of previous coatings using the latest technologies in the world, to produce UPVC roof covering sheets with the help of experienced workers and new equipment, internally and with pride. As a national production with the BTJ brand, we have entered the market in the construction industry of our beloved country.

paint resistance

ASA color resin, which forms the coating on the sheet, is the world's best technology for maintaining durability and not changing the color of the product in unfavorable weather conditions, heat, cold and UV rays.

Resistance to sun and UV rays

Roof coverings are always exposed to atmospheric factors such as light and heat from the sun, UV rays, etc. The resistance of these coverings against these factors should be one of the prominent features of this product. Due to the addition of the UV layer, these sheets are completely in They are resistant to sun and UV rays.

Light weight of the product

The weight of a roof is of great importance considering the load it imposes on the structure, the lighter the weight of a roof while maintaining its strength, the superior the product. PVC sheets are inherently light due to their polymer material. This cover is considered a light sloped roof and weighs only 3.5 kg per square meter, which adds the least dead load to the building in the discussion of lightening the building.

Heat and sound insulation

PVC sheets are very good heat insulators for two reasons. One: the inherent nature of this polymer is its low heat transfer coefficient, and two, due to the unique formula of this sheet, 80% of the light radiated to it is reflected. The thermal conductivity coefficient of these roof coverings is 325% W/m.k. This amount is 0.05% of galvanized sheets with a thickness of 0.5 mm.

In addition to the fact that PVC sheet has a low heat transfer coefficient, the sound transmission coefficient is also low in it, and it is nothing but resonant coatings in this sector.

PVC sheet with a thickness of 2 to 3 mils with 3 layers is suitable for sloping roofs, especially in the southern regions.

PVC sheet is the only product that has had good results in tropical areas compared to other roof coverings.

These sheets have stable color and quality from -30 to +70 degrees Celsius.

Ease of installation and implementation

Certainly, the ease and speed of implementation is very important and decisive in project timing and costs. Due to the appropriate surface tension and excellent reversibility (bending and tensile test), PVC sheets have provided enough peace of mind and confidence for the installer to easily move on the sheets and perform the execution operation, which causes the rise The executed speed and also the process of transferring the sheets to the top of the structure is possible easily and quickly due to the light weight and suitable flexibility of these sheets.

What is PVC sheet?

Polyvinyl chloride sheets, which are the same as PVC sheets, are among the products that are widely used in the construction industry. Usually, more than 40 million tons of these sheets are produced every year. PVC sheet is usually made of polyvinyl chloride materials as well as some other additives such as modifiers, lubricants, stabilizers, etc. Of course, the amount of composition of these materials will be determined according to the type of use.

PVC sheet materials will be combined and powdered in large mixers using very high heat. Then the obtained materials are molded in different sizes using special molds. Finally, after the sheets are dry, they will be chipped all around and packed in the form of pallets.

In general, it can be said that PVC sheets are made in different types, among which we can mention compressed PVC, foamed PVC and multilayer PVC. Compressed PVC is usually used for cabinets, wall coverings or the furniture industry. But foamed PVC
