In aluminium joinery systems, thermal insulation plays a critical role in energy efficiency. Thermal break technology minimizes heat transfer through polyamide barriers placed between the inner and outer surfaces of the aluminium profile.
How Does Thermal Break Work?
The thermal break system connects the inner and outer shells of the aluminium profile with polyamide (PA 6.6) strips. These strips break the high thermal conductivity of aluminium, significantly reducing heat transfer between indoor and outdoor environments.
Performance Values
- **Uf Value:** 1.2 – 2.8 W/m²K in TW series profiles
- **Sound Insulation:** 38 – 46 dB (depending on glass type)
- **Water Tightness:** 600 Pa (EN 12208)
- **Air Permeability:** Class 4 (EN 12207)
When Should It Be Preferred?
Thermal break systems are essential for energy savings in residential, office, and commercial buildings. They are preferred particularly under TS 825 and EPBD regulations to improve building energy performance classification.
ICS Alüminyum TW Series
ICS Alüminyum's TW 50, TW 60 and TW 76 series offer solutions for every project with different profile depths and polyamide widths. The TW 86 HI series provides ultra-low Uf values meeting passive house standards.
