Uetersen 2-hour refractory rock wool board is specially designed for various curtain wall systems. It has the characteristics of higher refractory temperature, higher melting point, longer fireproof aging and smaller high temperature line shrinkage.

　　Curtain walls are composed of panels and supporting structural systems, and are widely used in various commercial and public buildings. It has the functions of light weight, convenient installation, wind resistance and rain resistance. However, since the curtain wall has a cavity structure and the thermal resistance of the main structural material is small, fire safety and thermal insulation and energy saving are particularly important. Rock wool is an ideal fire blocking and thermal insulation partner for curtain walls.

　　Uetersen curtain wall fireproof rock wool board is not only used for fire prevention and smoke barrier between curtain wall and floor or between curtain wall and partition wall. It can also be used for fire blocking of other building gaps including gaps around pipes passing through walls or floors. In order to enhance the smoke barrier capability of the curtain wall fireproof series products, fireproof aluminum foil is generally attached to the upper and lower surfaces of the curtain wall fireproof rock wool board.

　　Excellent thermal insulation performance

　　The thermal conductivity is as low as 0.036w/(m·k), which greatly improves the energy saving effect.

　　Excellent fire performance

　　A1 grade non-combustible fireproof material, high temperature resistance up to 800°C.

　　Anti-aging Durability

　　Does not contain asbestos and meets EUCEB requirements; does not contain environmentally harmful substances in REACH and ROHs; does not support the growth of mildew and bacteria, healthy and environmentally friendly.

　　Low hygroscopicity and high hydrophobicity

　　Under natural conditions, lower moisture absorption rate (≤0.2%) ensures better thermal insulation performance; higher hydrophobicity rate (≤0.2%) ensures consistent performance in humid or watery environments.
