Production processes

Thermal
break

Our thermal break technique uses polyamide strips of various dimensions to interrupt thermal transfer through the aluminum profiles, while withstanding high temperatures and providing excellent resistance to aging.

What is a thermal break?

Precision at high
temperatures

Thermal break is a technique that enables the interruption of heat transfer through architectural aluminum profiles using thermal breaks, which in our case are polyamide strips of various dimensions (14.8 mm, 16 mm, 18 mm, 28.6 mm, 31.6 mm).

Polyamide strips withstand high-temperature, powder coating and anodization, and have an extremely thin structure that is resistant to tearing, abrasion, and the effects of aging. They insulate more than 500 times better than aluminum, which results in significantly lower Uf-values for profiles with a thermal break.

Dimension we can combine
in our thermal break section include:

Capacity

  • Maximum possible profile height of 400 mm
  • Maximum width between polyamide strips of 240 mm
  • Minimum possible distance between two polyamide strips on the profile of 8 mm
  • Minimum possible polyamide height of 14.5 mm
  • Maximum possible polyamide height of 60 mm

The height of the teeth for the reception should be approximately 3 mm

Material and thermal properties

Our use of low lambda (λ) polyamide with a value of 0.21 W/mK allows us to achieve high standards of thermal insulation in our systems. Our thermal conductivity results are::

  • Facades: 0,7
  • Windows and doors with broken thermal bridge: 1.1 (PE85tt)
  • Sliding doors: 1,0
