More than half of all the windows installed in Germany are made of PVC. This is mostly due to their outstanding energy efficiency, high quality, versatile colour range, easy care and longevity. It took a long time for PVC production to take off its negative image. ”Plastic“ was always considered as a cheap material for the interiour or exteriour. But nowadays PVC windows achieve particularly high scores regarding ecology issues. They also have great energy saving potential than any other window material and rank at the top of the league in eco-efficiency analyses. Very important for people to understand, that PVC WINDOWS FRAME MATERIALS IS 100% RECYCLED. Based on their high durability, cost, benefits PVC windows are the most sustainable solution available for windows today: it is twice cheaper than wooden windows, and trice cheaper than aluminium windows.

PVC windows from Inoutic offer an extensive range of advantages, not only from an ecological viewpoint but also in terms of economic efficiency and architectural design. Our plastic window systems demonstrate how advanced technologies are combined with practical benefits and appealing design. This is because plastic windows should not only save energy but also look good. Modern windows must provide effective protection against: the cold, adverse weather conditions and noise, they must be burglar-proof and boast an excellent cost-benefit ratio, they should also be easy to care for and require minimum maintenance. These are the precise requirements that are met by the Inoutic PVC window systems.

The passive house standard (Uw ≤ 0.8 W/m2K) can also be implemented cost effectively with standard triple glazing and plastick warm frame inside tha glazing. Need to pay attention that plastic warm frame prevents accumulation of muisture, as well prevents for "Cold Bridge" which appears in case there is no warm frame, but there is aluminium frame. The ENERGY PASSIVE profile is the only system without additional insulation, which is  certified as a passive house suitable component by the internationally renowned ift Testing Institute. ENERGY PASSIVE is available in two different designs as offset or semi-offset version. Besides outstanding thermal insulation the ENERGY PASSIVE profile is created to face your every need: floor to ceiling height of the window elements up to 2.6 m are possible thanks to the Inoutic bonding technology, a glazing thickness of up to 56 mm can be accommodated for special safety glass or acoustical insulation and a vast selection of colours and decors allow you to create your own individual style. You can even design the facades of passive houses to meet your individual needs.

WE are lucky, to let you know that Eforte systems was awarded in Poland Exhibition (2011) for the best ecologic parameters and got "THE QUALITY OF THE YEAR 2011" award.


  • 84 mm system, 6 chambers
  • Excellent frame thermal insulation value Uf = 0.95 W/m2K
  • Passive house standard certified by internationally renowned Testing Institute in Rosenheim (ift)
  • Insulation values of the overall window Uw up to 0.64 W/m2K, exceeding passive house standard requirements
  • Very cost-effective implementation of passive house standard using conventional triple glazing.
  • 2 different sash designs available 
  • Accommodates a glazing thickness of up to 56 mm
  • Inner 2-foot glazing bead for enhanced burglary protection
  • Glass rebate height of 25 mm for avoidance of condensation 
  • A special bonding technology enables floor-to-ceiling elements of up to 2.60 m in height
  • Soundproofing up to 47 dB (noise protection class 5)
  • 40 different laminated foil colours and an unlimited choice of colours with aluminium cladding 
  • The optional aluminium cladding offers the many advantages of a PVC window without having to omit the classic look of an aluminium window


Glass covers about 80 percent of the window area. Therefore, the selection of high-quality glass and glazing package is particularly important in order to maximize the window light and heat conduction properties. The biggest thermal insulation could be reached with a right choice of quality glass package (glazing). So when you are choosing the glazing for a plastic windows it is worth to pay attention to factors which must ensure quality glazing:

  • As low heat transfer outside as possible;                                                 
  • As high day ligh transfer inside as possible;
  • Watertight;
  • Long life and durability.


It is worth to mention that we offer our clients the glass packages with selective glasses. This glass is coated with a thin metallic oxide layer which retains a heat. Selective glass is placed inside of the glass package and it reflects heat back into the room. Window glazing with a new generation of soft selective glass coating spends 3 times less heat to the outside than regular glass package. It is also worth to  notice that selective glass minimize light transfer to the room (80-86%  light entering).






We offer a variety of thicknesses and different functionality 2-and 3-glass windows, which, depending on the client's needs using different types of glass and aluminum or a special warm frame. Standard insulating glass thickness of 40 mm to 44 mm. In the specific customer needs, as well as choosing a passive windows (ENERGY PASSIVE) we offer our customers 50 mm and 56 mm glass packages. With a such triple-glass, argon gas-filled glazing,  we can reach thermal conductivity coefficient up to Ug 0.5 W/(m2K) of glass.
Typically, the windows are glazed with a glass, which are made of glass with a thickness of 4 mm, at large constructions in order to isolate noise, and to keep construction stable we use  glass of 6 mm thick. Also, we offer our clients the matt, sun protected, laminated (secure) glazing.
Seeking optimum quality at an affordable price, experts recommend to make one of the glasses selective. This is a good decision, because selective glass on the inner side of the window  represents a sufficiently high thermal resistance and losing a small amount of the suny light transfer.

*** We guarantee all declared features of the glass, because they are tested in  notified laboratories and certified by the CE marking.



Coloured windows and doors emphasise design features and have a decisive impact on the facade. The wide selection of Inoutic window colours offers practically unlimited design possibilities and underscores a deep understanding of traditional and contemporary architecture. The coloured foils are either applied on one side or on two sides. Client can combine our colours in many different ways and even give your windows a different look on the inside and outside. The high quality and extremely durable laminated foils satisfy highest design and quality demands. Even years later the colours remain just as fresh as they were on the first day. They are also easy to care for and extremely resistant to temperatures and UV. The colours are available for the window profiles, roller shutter boxes, lift and sliding doors and front doors.
