Pre-wall Mounting System for thermal insulation

Why the Phonotherm^® Pre-wall Mounting System Stands Out

• Thermal Bridge-Free Installation:
  The Phonotherm^® Pre-wall Mounting System meets the requirements of the German Building Energy Act (GEG) and the EU Building Directive for thermal bridge-free window installation. It effectively minimises heat loss, improving overall  the energy efficiency.
• Outstanding Properties:
  With a thermal conductivity of 0.083 W/(m*K), the Phonotherm^® Pre-wall Mounting System ensures an optimal isothermal profile. It is resistant to moisture and ageing as well as rot-proof guaranteeing long-lasting durability and reliable performance.
• Sound Insulation:
  The Phonotherm^® Pre-wall Mounting System also excels in noise reduction. With a tested sound insulation rating of Rw = 59 dB, it effectively reduces noise pollution, creating a more comfortable living and working environment.
• Ease of Processing:
  Thanks to its compatibility with standard woodworking machines, the system can be easily customised on-site without requiring specialised tools saving both time and costs.
• Proven Load Transfer:
  The bonding of the system alone enables excellent load transfer, ensuring a secure and stable window fastening, which is component-tested according to MO-01/1 and MO-02/1.
• Future-Proof Solution:
  A later window replacement can be carried out without damaging the façade, ensuring long-term flexibility and sustainability.

Sustainable and certified

The Phonotherm^® Pre-wall Mounting System has been specially tested for the cool-temperate climate zone and has received the Passive House certificate in the category "Window Mounting Systems". This certification not only confirms the high energy efficiency of our product, but also its suitability to reduce built-in thermal bridges and ensure thermally improved window installation.

The Phonotherm^® Pre-wall Mounting System is listed in the component database of the Passive House Institute and can be easily integrated into the Passive House Planning tool PHPP (Passive House Project Planning Package). This makes it easier for architects and specialist planners to carry out precise energy efficiency planning.  In addition, by using the Phonotherm^® Pre-wall Mounting System verified Passive House Certificates can be submitted for KfW Bank subsidies.
