Is there a flexible roof product that has better thermal insulation and faster construction than traditional flexible roofs; better thermal insulation and waterproof performance than single-layer metal roofs; and better waterproof than metal-faced sandwich panels as well as economical. "BiTOP® Coil Surface Roof Sandwich Panell" can meet all the above requirements.

Product Overview

BiTOP® coil roofing system, developed by Wiskind and Oriental Yuhong, has been patented. It is a self-supporting composite plate composed of TPO coil and corrugated steel plate as the surface layer, and a special rock wool core material bonded between the surface layer. Manufactured ON the continuous sandwich panel production line in the factory, it is a fabricated building material product with advantages of different materials.

The sandwich panel is prefabricated by the factory, and the on-site installation process only requires three simple steps: positioning, nailing, and welding, bringing a new angle to the metal sandwich panel roof!

"Steel and softness" are combined, and high-quality materials are selected from the outside to the inside
Industry-leading L-type TPO membrane surface
Excellent bonding performance丨Excellent welding performance丨Excellent weather resistance
BiTOP® uses the leading TPO membrane of Oriental Yuhong as the surface layer, which has excellent bonding performance with rock wool insulation materials, and excellent welding performance, ensuring long-term reliability of joint waterproofing.
High quality rock wool core material
High strength丨Class A non-combustible
BiTOP® chooses high-quality rock wool as the core material, which can achieve Class A non-combustibility, compression resistance, trampling resistance, high bonding strength and high peel strength.

Corrugated steel plate
Optimized section丨beautiful and efficient
The base plate of BiTOP® is made of high-quality galvanized or galvanized steel. The cross-sectional properties of the profiled steel plate endow the plate with resistance to roof snow loads and live loads.
In order to meet the needs of indoor beauty and bright light, white color-coated steel plates can also be used.

Strong performance, strength to build
Strong thermal insulation to create a comfortable space
The large number of fasteners and gaskets in conventional flexible roofs are significant thermal bridges, while BiTOP® has no thermal bridge phenomenon and better thermal insulation.
Rock wool core material is preferred, with excellent thermal insulation performance.
High-strength wind resistance, not afraid of the wind
Its minimum configuration is sufficient to meet the wind resistance requirements of most industrial construction projects, and higher wind resistance requirements can be achieved by densifying the purlin or nail spacing.
Tailor-made special wind resistance design calculation program, based on various test data and specifications/standards for design calculation, to ensure the technical economy of the roof design scheme.
Excellent waterproof and worry-free roof
During the installation process: The surface layer of BiTOP® waterproofing membrane is fully adhered to the rock wool, and the installation process is few, and the waterproofness is good during the construction process.

Adaptable photovoltaic solutions
BiTOP® roofing supporting photovoltaic solutions, on the basis of reliable waterproofing, have better roof thermal insulation performance, and can exert the best photovoltaic module power generation efficiency.
Epilogue
Under the background of "double carbon", thousands of industries are changing in a green and sustainable direction. As an effective means to achieve the green and high-quality development of the construction industry, prefabricated buildings have also embarked on the road of rapid development.
As an important part of prefabricated buildings, prefabricated roofs also play a pivotal role in prefabricated buildings. As a leading supplier of metal enclosure products, Wiskind has been committed to promoting green buildings for more than 40 years. Through the launch of "BiTOP® Coil Surface Roof Sandwich Panel", Wiskind also hopes to reduce costs and increase for more construction projects. Effective, contribute to the development of prefabricated buildings!
