What is ISO 17738‑3 - Thermal insulation products about?
ISO 17738-3 discusses the design requirements for exterior insulation, and finish systems (EIFS) for thermal insulation products. Thermal insulation is used for protection, prevention, comfort, and economy. ISO 17738‑3 is the third part of the ISO 17738 series that specifies the design requirements, selection and application of exterior insulation, and finish systems (EIFS) for use by building designers, building code officials, product manufacturers, and contractors to sustain the installed performance, and durability of EIFS.
ISO 17738‑3 contains design requirements for the design, and installation of an EIFS as a wall cladding system. ISO 17738‑3 includes a selection of materials that meet the requirements of ISO 17738‑1, and installation requirements by ISO 17738‑2, and covers the interfaces between EIFS, and other building assemblies, and components. ISO 17738‑3 does not specify the structural design of the substrate to which the EIFS is attached, nor does it provide design requirements when the installation of EIFS uses mechanical fasteners.
ISO 17738‑3 does not address all aspects related to EIFS design, selection, and use. Working knowledge of applicable regional building codes, and regulations is helpful when working with ISO 17738‑3. There could be other considerations for specific installations that are not addressed by ISO 17738‑3.
Who is ISO 17738‑3 - Thermal insulation products for?
ISO 17738‑3 on the installation of thermal insulation products is helpful to:
- Manufacturers, and suppliers of thermal insulation products
- Contractors
- Civil engineers
Why should you use ISO 17738‑3 - Thermal insulation products?
Thermal insulation is used to ensure that there is no loss or gain of heat in a medium, and therefore must be very well chosen considering the properties, applications, and costs. It is used for protection, prevention, comfort, and economy.
ISO 17738‑3 provides specifications for architects, design professionals, and builders on the integration of an exterior insulation, and finish system (EIFS) into their projects. The design in ISO 17738‑3 contains five ‘planes of control’, they are:
- Water-shedding barrier
- Water-resistive barrier
- Thermal barrier
- Air barrier
- Vapour barrier
ISO 17738‑3 provides you with the design requirements which helps you to indicate details of interfaces, and joints, including flashings, required to maintain continuity of the water-shedding barrier (lamina), the water-resistive barrier assembly (WRBA), air barrier assembly, and the vapour barrier assemblies. This helps you in manufacturing thermal insulation products.
