EN 13162 Thermal Insulation Products for Buildings - Factory Made Mineral Wool (MW) Products - Specification

The European standard "EN 13162 Thermal insulation products for buildings - Factory-made mineral wool (MW) products - Specification" describes the requirements for factory-made mineral wool products, whether or not they have surfaces or coatings, used for thermal insulation of buildings. The products are manufactured in the form of mat sheets, boards or slabs. The products covered by this standard are also used in prefabricated thermal insulation systems and composite panels. The performance of systems containing these products is outside the scope of this standard.

This standard describes product characteristics and includes procedures for testing, conformity assessment, marking and labelling. This standard does not specify the required level of a particular characteristic that a product must achieve to demonstrate its fitness for purpose in a particular application. The levels required for a particular application are found in regulations or non-conflicting standards.

Products with a declared thermal resistance at 10 degrees less than 0,25 m²⋅K / W or a declared thermal conductivity greater than 0,060 W/(m⋅K ) are outside the scope of this standard. This standard does not cover in-situ insulation products covered by EN 14064-1 and EN 14064-2 standards, or products intended for insulation of building equipment and industrial facilities covered by EN 14303.

For the purposes of this standard, the following definitions apply in addition to the terms and definitions given in EN ISO 9229:

• Mineral wool is an insulating wool produced from molten rock, slag or glass.
• Level is the value that is the upper or lower limit of the requirement and is given by the declared value of the relevant attribute.
• A class refers to a combination of two levels of the same feature at which performance will degrade.
• It is a flexible fibrous insulation product that can be mat, blanket, faced or closed, and is supplied rolled or flat.
• Sheet, slab, is a rigid or semi-rigid (insulating) product with a rectangular shape and cross-section, whose thickness is uniform and considerably smaller than other dimensions. Sheet is generally thinner than slab. They can also be supplied in tapered form.
• A coating is a functional or decorative surface layer with a thickness of less than 3 mm, such as paper, plastic film, fabric or metal foil, which is not considered as a separate thermal insulation layer to add to the thermal resistance of the product.
• A coating is a functional or decorative surface layer, usually less than 3 mm thick, applied by painting, spraying, pouring or troweling. It is not considered as a separate thermal insulation layer to add to the thermal resistance of the product.
• A composite insulation product is a veneerable or faced product consisting of two or more layers bonded together by chemical or physical adhesion and consists of at least one layer of factory-made thermal insulation material.
• A multi-layer insulation product is a face-coated or face-coverable product consisting of two or more layers of a thermal insulation material of the same standard, bonded horizontally together by chemical or physical adhesion.

In order to comply with this standard in terms of product properties, products must meet the requirements of this standard. Mineral wool is anisotropic and the result of a measurement perpendicular to the surfaces is different for many properties (e.g. thermal and mechanical properties) from the result of a measurement parallel to the surfaces. For boards to make lamellar products, tests should be carried out taking the length as the thickness and the thickness as the length to test the performance of the final product. A test result for a product property is the average of the values ​​measured on a number of test specimens in the table given in the standard. For multilayer products, additional requirements are given in the annex of the standard (Annex C).

In all applications, thermal resistance and thermal conductivity shall be based on measurements carried out in accordance with EN 12667 or EN 12939 for thick products. Thermal resistance and thermal conductivity shall be determined in accordance with Annex A and declared by the manufacturer according to the following principles:

• The reference average temperature should be 10 degrees.
• Measured values ​​should be expressed with three significant figures.
• For products of uniform thickness, the declared thermal resistance should always be declared. Where possible, the thermal conductivity should be declared. Where appropriate, for products of non-uniform thickness (i.e. curved and conical products) only the thermal conductivity should be declared.
• The declared thermal resistance and declared thermal conductivity should be given as limit values ​​representing at least 90 percent of the production and determined with a 90 percent confidence level.
• The statistical value of thermal conductivity is given to the nearest 0,001 W/(m⋅K) and rounded to 0,001 W/(m)⋅K) should be declared in steps.
• The declared thermal resistance shall be calculated from the nominal thickness in the case of products with declared compressibility and, if not measured directly, from the corresponding thermal conductivity.
