Scope

This document specifies the characteristics for external thermal insulation composite kits with a rendering system (ETIC kits) for external walls and/or external finishes of walls (including cladding).

In this document, ETIC kits are used on external walls, which are made either of masonry (bricks, blocks, stones, etc.) or concrete (cast on site or as prefabricated panels).

With regard to the components, this document covers ETIC kits with:

a) adhesives, which are ready to use mortars, dry mixed mortars or PU adhesive foams, all specified in A.1;

b) thermal insulations, which are made of one of the following materials: mineral wool (MW), expanded polystyrene (EPS), extruded polystyrene foam (XPS), rigid polyurethane foam (PU), phenolic foam (PF), cellular glass (CG), expanded cork (ICB) or wood fibre (WF), all specified in A.2;

c) mechanical fixing devices, which are plate anchors, spiral anchors, profiles and rails with collar anchors or anchors for an anchored metal mesh, all specified in A.3;

d) base coats, which are ready to use or dry mixed, all specified in A.4;

e) reinforcements, which are glass fibre meshes or metal meshes, all specified in A.5;

f) key coats, all specified in A.6;

g) finishing coats, which are ready to use or dry mixed, all specified in A.7;

h) decorative coats, all specified in A.8.This document covers ETIC kits, which are fixed to the substrate either with adhesive or mechanical fixing devices or combination of both, clustered as the fixing methods (I to VIII), all defined in 3.1.3.1 to 3.1.3.8 and further specified in A.9.

This document specifies procedures for assessment and verification of constancy of performance (AVCP) of the ETIC kit characteristics.

This document does not cover:

— ETIC kits with the components and the fixing methods a) other those indicated above and b) not complying with the criteria for their parameters, further specified in Annex A;

— ETIC kits with other finishing layers than rendering systems, e.g. ceramic tiles, glass tiles, sand-lime-bricks, ceramic brick slips, natural and artificial stones;

— External insulation and finishing systems (EIFS), according to ISO 17738.
