What is BS EN 13496 - Mechanical properties of glass fibre meshes for ETICS about?
BS EN 13496 is a European Standard on thermal insulating products for building applications.
The main aim of the BS EN 13496 series is to provide manufacturers with best industry practices to demonstrate the performance of thermal insulation products, such that they are fit for its intended use.
BS EN 13496 specifies equipment and procedures for determining the tensile strength and elongation of glass fibre meshes which are used for the reinforcement of the base coat in External Thermal Insulation Composite Systems (ETICS).
Who is BS EN 13496 - Mechanical properties of glass fibre meshes as for ETICS for?
BS EN 13496 on thermal insulation products is relevant to:
- Thermal and sound insulating material manufacturers
- Glass fibre mesh manufacturers and suppliers
- Contractors
- Civil engineers
- Building owners/management
- Specifiers and installers
Why should you use BS EN 13496 - Mechanical properties of glass fibre meshes for ETICS?
Fibreglass mesh is used to strengthen the surface of the render and plaster layer in all types of structures for waterproofing and cracked plaster restoration to avoid cracking or fraying of the plaster and improve its mechanical strength.
In this regard, BS EN 13496 determines tensile strength of glass fibre meshes at failure using a tensile testing machine. It specifies the apparatus requirements to test thermal insulating specimens along with the number of specimens, dimensions and conditioning and test procedure.
Thus, if you are a manufacturer of thermal insulating products, complying with BS EN 13496 can help demonstrate the performance and credibility of your product, ensuring that they are fit for purpose.
By determining the tensile strength and elongation of glass fibre meshes, you can assess whether your products play a positive role in the overall establishment of ETICS in new or existing buildings, and that they contribute to optimal energy efficient and sustainable thermal insulation solutions.
