Advantages Of Aluminum Foil For Waterproofing Membrane

- Nov 07, 2019-

The use of waterproof membranes must be carried out in accordance with national standards. Whether or not the aluminum foil waterproofing membrane is toxic depends mainly on its function. The aluminum foil waterproofing membrane is divided into three parts, namely a self-adhesive layer, an intermediate layer and a waterproof surface layer, and the thickness is 1.5 mm. The main raw materials are butyl rubber, polyester, metal aluminum foil and the like. Among them, butyl rubber is mainly used for self-adhesive layer, which can enhance the adhesion of aluminum foil  water coil, is not resistant to aging, and is not easy to fall off, and can be used for a long time.


Most of the color steel plates with waterproof membranes are not flat. Therefore, a glass fiber polyester paving pad is specially added in the middle of the aluminum foil waterproofing membrane to effectively ensure that the coil is not easily deformed, and the coil has the functions of high temperature resistance and super waterproof. Moreover, the foil waterproofing membrane with the glass fiber polyester paving pad as the main raw material is softer and more stretchable, and can effectively prevent the corner deformation during the paving process.


The  aluminum foil  as the surface layer of the entire waterproof coil material greatly improves the physical properties of the coil material, and is moisture-proof and high-temperature resistant, and can be safely used between 80 ° C and 30 ° C without falling off. The metal aluminum foil has high ductility, a thin surface layer, strong sealing performance, corrosion resistance, and the aluminum foil has a high ignition point. Therefore, there is no need to worry about the ignition of the coil in daily use, and the safety factor is also high.



The aluminum foil waterproofing membrane has high tensile strength and soft material and can be applied to various rough and uneven base waterproofing. However, the ductility of the aluminum foil waterproofing membrane is slightly weaker than that of the waterproof coating,but the construction process of the aluminum foil waterproofing membrane is relatively simple and has no professional requirements. The separator under the web can be directly peeled off and attached to the base layer that needs to be waterproofed. The aluminum box waterproofing membrane has low requirements on the base layer. Even if there are holes or uneven colored steel surface layers, the factory can be directly laid, and only one layer can achieve waterproof effect. The whole construction process is relatively simple.
