BS EN 1279‑2 is part two of a multi-series of European standards on insulating glass units in building that covers long term test method and requirements for moisture penetration.
BS EN 1279‑2 describes the test method for the determination of moisture penetration index and specifies the requirements for limit values for insulating glass units made:
BS EN 1279-2 on insulating glass units - moisture penetration is useful for:
Insulated Glass combines two or more glass panes that are spaced apart and sealed with a sealant to appear as a single unit. Also called double glazing, IGUs are designed to reduce heat loss and solar heat gain entering the building, while reducing visible light transmittance. Hence, they improve the thermal performance, and reduce energy costs. They can be fabricated to meet sound control requirements, seismic requirements, bullet resistance, hurricane and blast resistance requirements, impact resistance and state energy codes.
Moisture penetration is caused when water enters a building from the outside through faulty rainwater protection equipment or infrastructure. It is common in buildings of all ages, especially in regions with varied climates.
With the use of BS EN 1279-2, you can evaluate the moisture penetration in buildings and with this information you make the necessary changes required to the production of glass so as to safeguard the users of your product. Ensuring this quality audit can help build credibility between your customers.
