What is BS EN 12091 - Freeze-thaw resistance of thermal insulating products about?
BS EN 12091 is a European Standard on thermal insulating products for building applications.
The main aim of the BS EN 12091 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 12091 specifies the equipment and procedures for determining the effect of successive cycling from dry conditions at -20 °C to wet conditions at 20 °C on the mechanical properties and moisture content of the product.
BS EN 12091 is applicable to thermal insulating products.
BS EN 12091 is intended to simulate freeze-thaw effects on thermal insulating products which are frequently exposed to water and low-temperature conditions, e.g. inverted roofs and unprotected ground insulation.
Who is BS EN 12091 - Freeze-thaw resistance of thermal insulating products for?
BS EN 12091 on thermal insulation products is relevant to:
- Thermal and sound insulating material manufacturers
- Contractors
- Civil engineers
- Building owners/management
- Specifiers and installers
Why should you use BS EN 12091 - Freeze-thaw resistance of thermal insulating products?
The freeze-thaw resistance is determined as the change in the amount of water absorbed and the change in compression strength or stress. Freezing takes place in the air while thawing in the water.
In this regard, BS EN 12091 specifies the apparatus requirements to test thermal insulating specimens along with their number, dimensions and conditioning and test procedure.
Thus, if you are a manufacturer of thermal insulating products, complying with BS EN 12091 can help demonstrate the performance and credibility of your product, ensuring that they are fit for purpose.
Ultimately, assessing the freeze-thaw resistance provides indications on whether your products are capable of adequate insulation and protection for the operational efficiency of the end-application, when exposed to extreme temperatures. Moreover, the results of the tests can also assist manufacturers in making improved decisions on insulating materials, that can contribute to overall product enhancement.
