No long-lasting protection without roof sheeting

Foil is absolutely necessary

Up to forty percent of a well-chosen and professionally constructed roof is made up of various system components. In addition to aesthetic, high-quality concrete tiles, accessories are also needed for a truly durable roof system. On the terranteto.hu subpage, which is specifically designed for designers, you will find useful information on roof tile selection and roof system accessories. What's more, you can choose from a range of roofing system packages, in which roofing membranes play a key role.

With very few exceptions, the requirements for roofs necessitate the use of underlayment beneath the roof tiles. As roof membranes act as a water drainage layer, their installation can increase watertightness to the required extent, thereby extending the service life of the building materials located under the tiles.

However, in terms of durability, the quality of the roofing membrane you choose does matter. Roof underlayments must meet a number of requirements: first and foremost, they must have W1 waterproofing properties, and adequate strength is also of paramount importance. With their high thermal resistance and humidity resistance, they must be highly adaptable to weather requirements and temperature fluctuations. They must be able to withstand humidity for long periods.

During roof construction or renovation, the roof may not be replaced immediately. In this case, the roof structure is exposed to UV radiation for up to weeks, so the quality of the roofing membrane will determine the extent of the damage. A well-chosen roof membrane not only contributes to a comfortable living environment, but also to the protection of the roof structure. As it is located in the middle of the layer system, its repair or replacement - if not chosen correctly - can only be solved at extra cost.
