Thermal insulation
The creation of a thermal break is obtained with the following 3 main processes:
Knurling
In order to obtain a highly stable profile, the insulation grooves on the inner and outer profiles are serrated (also called knurling).
Assembling lines
With this process, the strips are inserted in the inner and outer profiles.
Rolling or crimping
In this last process, the aluminium extrusions and the thermal strip are rolled under high pressure, so that the profile is fixed on position and meets the desired technical requirements.
