What is BS EN 4568-5:2017

BS EN 4568-5:2017 is a technical standard that specifies requirements for the performance of construction products used for external thermal insulation in buildings. It provides guidance on the design, installation, and use of these products to ensure the energy efficiency and durability of the building envelope.

Scope and Application

The scope of BS EN 4568-5:2017 covers a wide range of construction products used for external thermal insulation systems, including insulation materials, fixings, and finishes. The standard applies to new buildings as well as existing buildings undergoing refurbishment or retrofitting projects.

This standard is applicable to both residential and non-residential buildings. It takes into account various climatic conditions and geographical locations, providing solutions that can withstand different temperatures, humidity levels, and exposure to elements such as rain, wind, and UV radiation.

Performance Requirements

One of the key aspects of BS EN 4568-5:2017 is the establishment of performance requirements for external thermal insulation products. These requirements cover properties such as thermal conductivity, water absorption, mechanical resistance, fire behavior, and durability under normal operational conditions.

The standard sets minimum performance thresholds that these products must meet in order to comply with the regulations. It also defines specific testing methods and provides guidelines for assessing the conformity of the products with the established criteria.

Benefits and Implications

BS EN 4568-5:2017 brings several benefits and implications for both manufacturers and users of external thermal insulation products. For manufacturers, complying with this standard ensures that their products meet the required quality and performance standards, enhancing their market acceptance.

For users, such as architects, builders, and homeowners, this standard provides a guidance framework for selecting and installing high-quality external insulation systems. It helps to improve energy efficiency, reduce heat loss, enhance thermal comfort, and contribute to the overall sustainability of the built environment.

Furthermore, by implementing BS EN 4568-5:2017, governments and regulatory bodies can establish a more robust and consistent approach to energy efficiency in buildings, contributing to the reduction of greenhouse gas emissions and the achievement of national and international sustainability targets.
