In Alpha

a contemporary design

The range IN ALPHA proposes a  joinery system in 70 and 80 mm, various  patented and exclusive innovations which meet the requirements of thermal, acoustic and mechanical performances.  It is submitted to a registered  DTA with the CSTB.

  • Profiles in multiple chambers for a strengthened heat  insulation.
  • Double sealing for a maximal heat and phonic insulation
  • Joints of glazing and white counter closures for a better esthetics (black for  a color PVC)
  • Free- leaded PVC use (stabilization in  Calcium Zinc)
  • Protect handlers ‘ health thanks to a lower weight
  • Available in a wide range of finishes


Fiberglasses are integrated into color profiles for:

  • delaying  the necessary steel  strengthening for color joineries, more sensible to heat.
  • Supressing  thermal decreases created by traditional steel  reinforcements
  • Lightening  joineries to protect  rotation axes  and increase the life expectancy of the window.
