BS EN 14314 is the European standard for thermal insulation products that consistently offer the intended resistance to heat flow throughout the building's lifetime.
BS EN 14314 specifies the requirements for factory-made phenolic foam products which are used for the thermal insulation of building equipment and industrial installations with an operating temperature in the range of approximately - 200 °C to + 120 °C.
Below an operating temperature of - 50 °C, special tests regarding the suitability of the products in the intended application are advised (e.g., liquefaction of oxygen). The manufacturer’s advice should be heeded in all cases.
The products are manufactured in the form of blocks, faced or unfaced, boards, pipe sections, segments and prefabricated ware.
BS EN 14314 describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
Products covered by BS EN 14314 are also used in prefabricated thermal insulating systems and composite panels, the performance of systems incorporating these products is not covered.
Note 1: BS EN 14314 does not specify the required level of a given property that should be achieved by a product to demonstrate fitness for purpose in a particular application. The 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 0,050 W/(m·K) at 10 °C are not covered by BS EN 14314.
Note 3: BS EN 14314 does not cover products for in situ insulation (blowing or pouring) or products for the insulation of the building structure.
Note 4: BS EN 14314 does not cover the following acoustical aspects: direct airborne sound insulation and impact noise transmission index.
BS EN 14314 on thermal insulation products for buildings is useful for:
Phenolic foam is a rigid cellular foam, the polymer structure of which is made primarily from the polycondensation of phenol, its homologues or derivatives, with or without aldehydes or ketones.
BS EN 14314 provides the properties of thermal insulation products to measure thermal resistance and thermal conductivity.
The classes of dimensional tolerances are specified in BS EN 14314 giving measures of length and width, thickness, squareness and flatness.
BS EN 14314 navigates you through the chemical, mechanical and physical properties of factory-made phenolic foam (PF) products.
Sampling, conditioning and dimensions of test specimens are determined by BS EN 14314 for the determination of thermal resistance and thermal conductivity.
The designation code for a phenolic foam (PF) product is illustrated in BS EN 14314.
BS EN 14314 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 phenolic foam products for the insulation of buildings are set out in BS EN 14314.
Furthermore, BS EN 14314 guides you through the production of phenolic foam products for building heating, ventilation, and air conditioning applications, ensuring thermal performance, moisture resistance, fire performance, and even structural strength.
As a result, the phenolic foam may be used in a variety of architectural applications, including roofing, cavity board, external wallboard, plasterboard dry lining systems, wall insulation, and floor insulation, providing improved fire performance and expanding the market.
