Full title and description

STB DIN 18515-1 2023-06 — Cladding for external walls: principles for design and application; Part 1 — tiles fixed with mortar. This document corresponds to DIN 18515-1:2023-06 and sets out requirements and guidance for the planning, material selection and execution of mortared tile or slab facings on external building walls.

Abstract

This standard defines the principles for design and workmanship of external wall claddings consisting of tiles or slabs fixed in mortar. It replaces earlier editions of the part (previously published versions include 2017 and earlier) and clarifies applicability limits (tile/slab thickness, weight and adhesive area), requirements for materials (frost resistance, compatibility), joint proportions and basic durability/weathering considerations. The document is intended to be used without a special verification of condensation for typical mortared claddings with joint proportions above specified thresholds.

Scope

Applies to mortared tiles or slabs used as exterior wall cladding of buildings and building components. The standard is applicable where the cladding is fixed in mortar and the joint proportion exceeds the specified minimum (commonly referenced as > 5 % in the guidance). It sets dimensional and mass limits for components (for example, nominal thickness categories with accompanying maximum total thickness for textured surfaces, and special conditions for tiles/slabs with nominal thicknesses above 15 mm but not exceeding 30 mm including requirements for dead weight and minimum adhesive area). The standard addresses material requirements, substrate conditions, mortar and adhesive selection, jointing and basic detailing for weather protection and durability.

Key topics and requirements

• Definitions and application limits for mortared tile and slab claddings on exterior walls.
• Material requirements (frost resistance, strength and suitability of tiles/slabs, mortars and ancillary materials).
• Dimensional and mass limits for tiles/slabs (nominal thickness categories, total thickness allowances for textured surfaces, dead weight and minimum adhesive area criteria).
• Design principles for attachment and support (mortar bedding, anchoring where applicable, substrate preparation).
• Jointing rules and recommended joint proportions to ensure durability and drainage.
• Considerations for thermal movement, moisture transport and prevention of condensation-related damage in typical applications.
• Execution quality, inspection and maintenance recommendations to achieve expected service life.

Typical use and users

Used by architects, façade engineers, structural and building-services consultants, contractors and specialist installers of tile and slab facades, manufacturers of tiles and mortars, building control authorities and conformity assessment bodies. The standard is referenced in specifications, tender documents and technical approvals for exterior wall cladding projects.

Related standards

Part of the DIN 18515 family of documents on exterior wall claddings. Relevant related standards include other parts of the DIN 18515 series (e.g., Part 2 addressing facing bricks fixed in mortar on supports) and complementary DIN/EN standards dealing with masonry, thermal and moisture protection, and construction materials. Users should also consider applicable national and European standards for structural design, product specifications and fire/thermal behaviour when designing claddings.

FAQ

Q: What is this standard?

A: It is the technical specification (STB DIN / DIN) for cladding external walls with tiles or slabs fixed in mortar (DIN 18515-1:2023-06), giving principles for planning and execution to ensure durable, weather-resistant façades.

Q: What does it cover?

A: It covers applicability limits, material and mortar requirements, substrate preparation, jointing and detailing, dimensional and mass limits for tiles/slabs, and recommendations for execution, inspection and maintenance of mortared exterior claddings.

Q: Who typically uses it?

A: Architects, façade and structural engineers, contractors and specialist installers, product manufacturers and building control/approval bodies use this standard when designing, specifying or assessing mortared tile and slab facades.

Q: Is it current or superseded?

A: The 2023-06 edition is the current edition of DIN 18515-1, replacing earlier editions (including the 2017 edition). Check national adoption notices where required.

Q: Is it part of a series?

A: Yes. DIN 18515 is a multipart series addressing different types and methods of external wall claddings (tiles fixed with mortar, facing bricks on supports, etc.). Other parts should be consulted for alternative cladding systems and for complementary technical rules.
