A perfect solution for demanding Clients!
Modern design, innovative technology and high energy efficiency that ensure lower heating bills!


  1. Energy efficiency as a result of the optimal profile structure, specially designed sealing system made of foamed EPDM and glass packages with low thermal transmittance.

  2. Modern design that is guaranteed by the slim, round-shaped profiles.

  3. High safety level guaranteed by two anti-burglary bolts in standard.

  4. Wide range veneer colours that ensures numerous interior design styles.

  5. Good parameters of sound insulation that ensure acoustic comfort even in places with intense traffic.

  6. Great parameters of air permeability and water resistance as a result of using triple sealing.

  7. System offers great resistance to wind  load thanks to optimal reinforcement.

  8. The possibility to execute in the so-called thin wielding technology V-Perfect, that allows to connect the profiles perfectly and it guarantees better clamp and wielding control, and, as a result, very good parameters in the resistance tests of the corners.

Iglo Energy Classic Anthracite Core

Anthracite Core in the Drutex PVC Profiles

Drutex introduced to its range PVC core in the colour of anthracite. This action has extended the already vast product range of options for this collection from this leading European producer. 

In the past, the preferential demand from clients for door and window carpentry has seemingly not been met, as most producers offer only white as the available colour. Drutex, being the forerunner of a multitude of solutions in the field, offers a few dozen colour possibilities in PVC carpentry. 

In the case of double sided veneer, the introduction of another colour for the core, besides white and brown, will allow the entire profile of the window to have continuous colour throughout the window frame. This can be observed especially well when the window is open.

“The new PVC anthracite core colour will definitely make our extensive array of world-wide products more attractive to clients. This is another step in the direction for our products to be even more competitive, as it creates further options and opportunities for customers who prefer the toned-down, grey shades, so popular in modern architecture.” Marcin Kloska, Commercial Director, Drutex S. A.

The solution is available in the seven chamber system Iglo Energy Classic. This system is produced entirely from primal material in the highest quality A class PVC. The frame and sash installation depth in this system is 82 mm.
