Sealing of regulated / non-regulated areas The sealing of buildings is, inter alia, dened in DIN 18195 Waterproong of buildings. Additional rules and standards are included on the ZDB information sheet for composite sealing elements. A relatively new set of rules is provided by ETAG 022. Here, sealings are regulated from a European perspective. In principle, sealings should work and ensure that no damage to the structural element or any impairments in terms of hygiene are caused by water, humidity as well as by other media such as lyes or acids. Which sealing is the most appropriate is dependent...

Decoupling with wedi building boards Decoupling is to be considered as an intermediate layer that neutralises any tensions coming from the surface. Decoupling systems are not standardised; they can both be used as acoustic decoupling and as thermal decoupling. The wedi building board can be used as decoupling between tiles and critical surfaces in all strengths. Furthermore, the wedi building board can also be used as thermal decoupling. If, for example, an electric oor heating is installed, the wedi building board can be used as thermal decoupling to the surface. The wedi building board ensures...

wedi Subliner Dry Technical data wedi Subliner General product description Thin-layer, crack-bridging sealing membrane made from highly tear-resistant polyethylene lm that ensures excellent adhesion of tile-setting compounds thanks to its special eece layer on each side. This product can be used with ceramic tiles and slabs and with natural stone cladding for internal walls and oors to provide quick sealing for projects with a tight deadline. Applications wedi Subliner Dry is a membrane sealing system for humid areas with moderate load, i.e. moisture exposure class A0 as per the ZDB data sheet;...
