EN 12086: Water vapor transmission properties of thermal insulation products

European standard EN 12086 specifies a testing procedure to determine the water vapor transmission rate, permeance, and permeability of construction products, particularly those used in thermal insulation applications.

Testing according to EN 12086 is typically required to show that several categories of building products meet the applicable harmonized technical specifications, making them eligible for the CE marking. Examples of products that may require testing include:

• Screed materials (EN 13813)

• Factory-made thermal insulation products, including mineral wool (EN 13162), expanded polystyrene (EN 13163), extruded polystyrene foam (EN 13164), rigid polyurethane foam (EN 13165), phenolic foam (EN 13166), cellular glass (EN 13167), wood wool (EN 13168), and wood fiber (EN 13171).

The higher displayed price applies to the first sample, while the lower price applies to subsequent samples delivered in the same sample set.
