As one kind of building insulation material, polyurethane break the traditional building materials - waterproof panel is not insulation, insulation panel is not waterproof, waterproof layer once the leakage, the insulation layer immediately lost the function of insulation. Compared with other single-function insulation or waterproof material, polyurethane has obvious advantages:

1, Polyurethane has a multipurpose function, at the same time, it has insulation, waterproof, sound insulation, vibration and many other features.

2, The excellent insulation properties of polyurethane, it is currently the lowest thermal conductivity(≤ 0.024) of all building materials, the highest thermal resistance of the insulation material, thermal conductivity is only a half of EPS foam polystyrene board.

3, Polyurethane continuous dense skin and nearly 100% high-strength interconnection wall, with the ideal impermeability. The use of spraying method to achieve waterproof insulation layer continuous seamless, the formation of seamless roof and the overall external wall insulation shell, the waterproof and impermeable performance is excellent.

4, Polyurethane has super self-adhesive performance (without any intermediate bonding material), anti-wind and anti-negative wind pressure performance is good; the overall spraying construction, completely eliminate the "hot section" and "cold bridge", flexible gradient technology can effectively prevent the waterproof layer cracking; mechanized operations, automatic ingredients, uniform quality, fast construction, short cycle.
