Knauf - Efficiency Appliances

The evolution of regulations pushes manufacturers to develop increasingly more efficient appliances. One of them, air recovery units, must have less than 3% of air leak of nominal airflow to be certificate. This target is impossible to reach with the “classic” approach towards appliance manufacturing: Metal sheet plus insulation stick. EPP technology enables a fully airtight casing thus limiting assembling areas. In addition, although it varies from one to another, in the projects we were involved, we have seen a strong 40% reduction in assembly times in production.
