Energy-efficient Abakus Energy windows

  • Arte profile of 84 mm casement's construction depth,
  • Roto NT fittings with RotoSil Nano coating,
  • class A profile, both sides in colour or with an additional external pigmented coating,
  • balcony windows reinforced with 2 mm steel panels,
  • optional triple glazing with U-value equal to 0,5 or 0,6W/m2K,
  • gaskets bonded in corners,
  • bonds made according to Abakus IRMC technology,
  • outstanding heat transfer coefficient of the window Uw equal to 0,8 W/m2K,
  • Swisspacer - thermal spacer bar,
  • Roto Secustic handles,
  • five-year warranty for the whole window.


In our energy-efficient Abakus Energy windows we use warm Salamander profiles and, optionally, triple glazing (44 mm thick) with Ug = 0,5W/m2K. Multi-chamber construction of PVC profiles and properly adjusted steel reinforcements make it possible for our windows to achieve one of the lowest heat transfer coefficients. It all means that we are witnesses of a thermal revolution affordable for all. As a result, energy-efficient Abakus Energy windows achieve, in their category, one of the best heat transfer coefficients Uw equal to 0,8 W/m2K, without necessity to use additional expensive inserts or insulation.

Profile Five-chamber Salamander profile with construction depth of 73 mm, with two gaskets impacting energy costs and noticeably reducing them.
Standard double glazing with Ug equal to 1,1 W/m2K, equipped with Swisspacer that guarantees good protection against heat loss and higher light transmittance. There is a possibility of substituting double with triple glazing for a surcharge.
Fittings Metal parts of our fittings are galvanized, chromatized and covered with RotoSil Nano coating. Thanks to all those processes, fittings are optimally protected against corrosion. Their special construction ensures high level of anti-pry protection, already in their standard version.
