What is BS EN 14309 - Factory-made expanded polystyrene (EPS) products about?
BS EN 14309 is the European standard for thermal insulation products that consistently offer the intended resistance to heat flow throughout the building's lifetime.
BS EN 14309 specifies the requirements for factory-made products of expanded polystyrene which are used for the thermal insulation of building equipment and industrial installations with an operating temperature range of approximately - 180 °C to + 80 °C.
Modified expanded polystyrene polymers with a higher temperature resistance are also covered by BS EN 14309.
Below an operating temperature of - 50 °C, special tests regarding the suitability of the product in the intended application are advised (e.g., liquefaction of oxygen). Manufacturers’ advice should be heeded in all cases.
The products are manufactured in the form of faced or unfaced boards, rolls, lags, pipe sections or other prefabricated ware.
BS EN 14309 describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
Products covered by BS EN 14309 are also used in prefabricated thermal insulation systems and
composite panels, the performance of systems incorporating these products is not covered.
Note 1: BS EN 14309 does not specify the required level or class of a given property that should be achieved by a product to demonstrate fitness for purpose in a particular application. The classes and levels required for a given application can be found in regulations and invitations to tender.
Note 2: Products with a declared thermal conductivity greater than 0,060 W/(m·K) at 10 °C are not covered by BS EN 14309
Note 3: BS EN 14309 does not cover products for in situ insulation (for loose-fill or poured insulation) or products for the insulation of the building structure.
Who is BS EN 14309 - Factory-made expanded polystyrene (EPS) products for?
BS EN 14309 on thermal insulation products for buildings is useful for:
- Builders
- Architects
- Manufacturers of thermal insulating products
- Manufacturers and suppliers of thermoplastic polymers
- Polystyrene manufacturers
Why should you use BS EN 14309 - Factory-made expanded polystyrene (EPS) products?
Expanded Polystyrene (EPS) is a white foam thermoplastic material produced from solid beads of polystyrene primarily used for packaging, insulation, etc.
BS EN 14309 provides the properties of thermal insulation products to measure thermal resistance and thermal conductivity.
The classes of dimensional tolerances are specified in BS EN 14309 giving measures of length and width, thickness, squareness and flatness.
BS EN 14309 navigates you through the chemical, mechanical and physical properties of factory-made expanded polystyrene (EPS) products.
The designation code for expanded polystyrene products is illustrated in BS EN 14309.
Sampling, conditioning and dimensions of test specimens are determined by BS EN 14309 for the determination of thermal resistance and thermal conductivity.
BS EN 14309 provides the Assessment and Verification of Constancy of Performance (AVCP) with the compliance of the product with the requirements and the performance determination of product type by type testing and factory production control.
Marking, labelling and packaging of the expanded polystyrene products for the insulation of buildings are set out in BS EN 14309.
Overall, BS EN 14309 leads you through the manufacturing of expanded polystyrene (EPS) products that are simple to install on the building site while maintaining durability and strength, which aids in the prevention or minimization of product damage.
As a result, EPS may be used as an insulation product that is extremely resistant to biological corrosion while also limiting the impacts of moisture and water vapour.
