Certified products have undergone independent uniform testing by the Passive House Institute. This allows useful quick comparisons and eases the task for designers to confidently specify high-quality, energy-efficient productsFor the designer, assessing the energy efficiency of components and the specific values that have to be used can be rather difficult. Specific values as described in national or regional standards are very often unrealistic or not accurate enough; reliable project planning using manufacturers’ information alone is often not possible.

Herman Van Damme MD of Hevadex (the Manufacturer) told us “I am delighted we have obtained this certification, the rigorous testing it’ is put through by the Institute really proves the superior performance of  Blowerproof  for use in passive buildings and  is recognised by designers as a certification they can rely on, it helps make everyone more comfortable about specifying and using Blowerproof.”

As an independent authority, the Passive House Institute tests and certifies products based on their suitability for use in Passive Houses. Products that carry the “Certified Passive House Components” certificate have been tested according to uniform criteria; they are comparable in terms of their specific values and are of excellent quality regarding energy efficiency. Their use facilitates the designer’s task and significantly contributes to ensuring the faultless functioning of the resulting Passive House.
