A large number of fasteners and gaskets in conventional flexible roofing are significant thermal bridges, while the fasteners used in BiTOP® are deeply buried in the roofing substrate, so there is no thermal bridge phenomenon and better heat insulation; BiTOP^® is made of preferred rock wool core material, with excellent thermal insulation performance of 100 thickness, and the heat transfer coefficient ≤ 0.40 W/m2-k is obtained by real sample test; the thermal insulation performance of BiTOP® of 100 thickness can meet the thermal performance requirements of most industrial buildings except the cold AB The thermal insulation performance of BiTOP^® 100 thickness can meet the thermal performance requirements of most industrial building roofs, except for the cold AB zone (about 45°N north).

The minimum configuration of Be-Tech BiTOP^® is sufficient to meet the wind resistance requirements of most industrial building projects (basic wind pressure ≤ 0.5kPa), and by increasing the purlin or nail spacing, higher wind resistance can be achieved;By increasing the purlin or nail spacing, higher wind resistance can be achieved; a tailor-made wind resistance design calculation program, based on various test data and codes/standards, ensures the technical economy of the roofing design.

During installation: conventional flexible roofing is difficult to protect the finished product between installation processes, and the insulation is susceptible to moisture absorption during the rainy season. BiTOP^®'s waterproofing membrane is fully adhered to the rock wool, and the installation process is less, so the construction process is waterproof; in service: conventional mechanically fixed flexible roofing systems bulge during stormy weather, blocking rainwater from draining down to the gutter, forming water at the coil joints, and after the coil bulges, a cavity is formed between the coil and the insulation, forming a negative pressure, and if there are defects in the welding, rainwater may be sucked in If the welding is defective, rainwater may be sucked into the lower part of the coil to form leakage. Be-Tech BiTOP^® roofing system, the coil and insulation rock wool full bonding fixed, the joints smooth slope, to overcome this defect.

BiTOP^® Roof supporting photovoltaic solutions, on the basis of reliable waterproof, roof insulation performance is better, and can play the best photovoltaic module power generation efficiency.
BiTOP^® The lightweight, ultra-thin design of flexible monocrystalline silicon ultra-thin components used in the roof, the weight is as light as 3kg/㎡, the thickness is as thin as 2.5mm, to meet the needs of various low-load projects.
