Construction product CE marking is a European procedure that verifies and certifies the properties of the product in a uniform and comparable manner. A Declaration of Performance (DoP), in which you can find all relevant product information, is published for each CE-marked product. Product information is applied in construction according to the Classification of Buildings category, so it is important that this is clear before purchasing insulation material.
The lower the thermal conductivity, the better the insulation. The thermal resistance of Termex Cellulose insulation remains uniform throughout its density range (26–60 kg/m3), regardless of the installation method.
High airflow resistance prevents heat loss caused by natural convection (air movement). The air flow resistance of Termex Cellulose insulation changes as its density changes. For example, with an insulation thickness of 450 mm, the air flow resistance is 6 kPa*s/m2, and convection is not accounted for in calculations.
The European fire class (A-F) gives information about a product’s fire properties. B =very low contribution to fire. Termex Cellulose insulation burns slowly by smouldering, without losing its volume (= no melting), even at high temperatures.
Water vapour permeability indicates a product’s resistance to water vapour. The lower the number, the better the vapour passes through the insulation material. Moisture transfers mainly in the hygroscopic area of the cellulose insulation, meaning that it insulates well even when moist.
Mould index 0 = the product passes a strict test without growing mouldy
<10 %(dry open blow: attics, intermediate floors and floors)
0% (forced blowing: wall cavities, pitched roofs and floors)
0% (Sidox installations: attics and walls)
Specific heat capacity indicates how much energy is needed to change the material’s temperature by one degree. The higher the heat capacity, the longer it takes to change the material’s temperature.
Global warming potential indicates the quantity of climate emissions the manufacturing of the product causes (negative climate impact).
Biogenic carbon storage indicates how much carbon the manufacture of the product binds from the atmosphere (positive climate effect).
