What is BS EN 14063-2 - Specification for the installed expanded clay LWA products about?
The quality and performance of thermal insulation products are critical when it comes to achieving operational energy efficiency in buildings, as they can effectively minimize heat loss and heat gain, as per the external weather conditions.
BS EN 14063 is a European Standard on thermal insulation products for buildings. The main aim of the BS EN 14063 series is to provide manufacturers with best industry practices to demonstrate the performance of thermal insulation products, such that they are fit for the intended use.
BS EN 14063-2 is the second part of the BS EN 14063 series that specifies the requirements for loose-fill expanded clay lightweight aggregate (LWA) products installed in roofs, ceilings, floors and ground floors.
BS EN 14063-2 describes the product characteristics that are linked to the essential requirements of the EU Construction Products Directive.
Note 1: BS EN 14063-2 does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in national regulations or non-conflicting standards.
Note 2: BS EN 14063-2 does not cover factory made expanded clay lightweight aggregate products or in-situ products intended to be used for the insulation of building equipment and industrial installations.
Note 3: BS EN 14063-2 does not specify performance requirements for airborne sound insulation and for acoustic absorption applications.
Who is BS EN 14063-2 - Specification for the installed expanded clay LWA products for?
BS EN 14063-2 on the specification for the expanded clay LWA installed products is useful for:
- Thermal and sound insulating material manufacturers
- Clay LWA products manufacturers
- Contractors
- Civil engineers
- Consultancies for thermal insulation
- Specifiers and installers
- Quality control and testing personnel
Why should you use BS EN 14063-2 - Specification for the installed expanded clay LWA products?
Expanded clay LWA is an insulation material or product composed of lightweight granular material having a cellular structure formed by expanding clay minerals by heat. When used as a thermal insulation material, expanded clay is mainly used to fill voids and contributes to improving the thermal and sound insulation of suspended floor constructions.
In this regard, BS EN 14063-2 provides guidelines for installing insulation products as well as the in-situ measurement of the thermal resistance, insulation thickness and moisture content.
BS EN 14063-2 also specifies the checks and tests to be used for the declarations made by the installer of the product.
BS EN 14063-2 specifies the test method to determine the density and compaction of the insulation product correlated to a sample of the delivered expanded clay LWA.
Thus, if you are a manufacturer of clay LWA products for thermal insulation, complying with BS EN 14063-2 can help demonstrate the performance and credibility of your product, ensuring that they are fit for purpose.
