Passive house-certified for arctic climate

With its low thermal transmission coefficient (Psi=0.029 W/mK*), Thermix Low Psi makes a crucial contribution to achieving impressive Uw values as are required for low-energy and passive houses. This has now been confirmed by the Passive House Institute with a certificate in the category "Spacers in thermally insulating glazing".

The certification of passive houses ensures that the stringent requirements of the passive house standard are met. This standard is characterised by a very high level of energy saving compared to conventional new buildings. Not only buildings but also individual components can be certified by the Passive House Institute. This allows planners to more easily assess components in respect of their energy efficiency, durability and energy characteristics

The Institute has tested the new warm edge spacer for the prevention of mould through a higher temperature in the glass edge zone (known as the hygiene criterion). Thermix Low Psi was found to be suitable as a spacer for the climate zone “arctic” and all zones with lower requirements.

Thermix Low Psi consists of polypropylene (PP) with a high glass fibre content – a material composition which counteracts brittle fracture effectively. The benefits for processors:

Resilient during frame production and handling and during muntin bar attachment
Fewer rejects and less postprocessing 
Time and cost savings during insulating glass manufacture

* Triple glazing, Ug = 0.7, wooden frame in accordance with the ift guideline
