TS EN 13956

TS EN 13956 relates to a standard covering the definitions and characteristics of flexible plastic and rubber sheets used for roof waterproofing. In technical terms, these products are membrane-type waterproofing materials intended to form a continuous barrier against water ingress in roofing systems, with their suitability typically understood through material composition, flexibility, joint behaviour, and resistance to environmental exposure.

What plastic and rubber roofing sheets mean in general technical use

In general engineering context, plastic and rubber sheets are thin, flexible membrane products used to reduce or prevent water penetration in roof assemblies. Plastic-based sheets are usually identified by their polymer structure, while rubber-based sheets are associated with elastomeric behaviour, which can help them accommodate movement and complex detailing. That distinction matters in areas such as roof edges, penetrations, and joints, where the membrane must follow structural movement without losing continuity.

Technical vocabulary and product character

The phrase “definitions and characteristics” indicates a focus on consistent terminology and the core properties used to describe this product family. Standards of this kind help align how roofing membranes are named, compared, and documented, so that manufacturers, specifiers, and installers are speaking about the same material categories and performance-relevant attributes. This is especially useful where different membrane types may look similar but behave differently in service.

This record belongs to a withdrawn standard, so current projects should rely on the latest applicable documents rather than treating it as an active reference. Even so, TS EN 13956 remains a useful technical reference point for understanding the vocabulary and product family of flexible plastic and rubber roofing waterproofing sheets.
