The Corotop® STRONG roof membrane is a three-layer product of increased GSM (grams per square metre) and strength parameters. Its high vapour permeability (2000g/6000 g/m2/24h) makes it ideal for building industry as a membrane for insulated steep roofs of all kinds, both with and without roof board and for housewrap. It is a product featuring enhanced strength having high resistance to mechanical damage, which ensures high installation comfort.
Thanks to the use of a functional film (polypropylene film) and increased strength parameters in the production process, the product has a high degree of waterproofness (> 1500/4500 mm H2O), which means that it is highly resistant to water and moisture while providing the opportunity to carry out assembly work in any atmospheric condition. Special stabilization additives cause the product to have an increased resistance to UV rays (even up to 3 months), meaning that the final covering of the roof can be done at a later date.
Use of the latest technical inventions and very efficient technology made it possible to offer a product of a very high quality at an affordable and attractive price. There are special imprints on the product that facilitate overlapping, and the original label and the Corotop® STRONG logo guarantee the stability of the product's quality and its genuineness.
Thanks to the Corotop® STRONG membrane the life span of your attic and the roofing system is significantly increased, which guarantees that your house will be dry and that the climate within it will be healthy.
