  • a double pane set Ug=1,1 W/m2K 4/16/4 with an aluminium frame
  • MACO MULTI MATIC KS Austrian fittings
  • aluminium handles
  • thermal transmittance factor of Uf=1,3 W/m2K
  • thermal transmittance factor of the reference window – 1230 x 1480 Uw=1,29 W/m2K
  • gaskets exposed to weather conditions in the colour black, an interior glazing bead with a grey gasket
  • a unique design owing to a rounded glazing bead
  • environmentally friendly owing to its recyclability
  • an undersill board facilitating the assembly of interior and exterior windowsills


Termo Optimum System

The Termo Optimum System is a profile of a low thermal transmittance factor that still comes in competitive prices.

Technical parameters:

  • WITAL PRESTIGE THERM profile
  • large chambers enabling for a proper ventilation of this profile and for removal of rainwater
  • a 6-chamber system with 86 mm installation depth

  • thermal transmittance factor Uf=1,0 W/m2
  • thermal transmittance factor of the reference window – 1230 x 1480 Uw=0,81 W/m2K
  • higher structure rigidity achieved by applying an enclosed profile reinforcement in the frame. In veneered windows the profiles include a 2 mm thick reinforcement.
  • MD system with a middle gasket (the third gasket in the set)
  • an additional gasket in the glazing chamber that improves the structure’s thermal properties
  • a “golden line” that is unique to REDAN windows
  • gaskets exposed to weather conditions in the colour black, an interior glazing bead with a grey gasket

KBE ECO Plus System

The KBE Eco Plus system provides the best balance between price and quality.

For economical reasons, windows made of plastics make it possible to reuse the PVC. Introducing KBE ECO PLUS windows is a sign of trust shown to the concept of reusing the original material. Owing to a deep window rebate, additional warmth or sound insulation and burglary protection can be applied. The interior rigid core can also be made from closed steel; producing it with very high quality materials increases the profile’s stability.

Technical parameters:

  • KBE NOVA profiles
  • a 5-chamber system with a 70 mm installation depth
  • an interior rigid core made with the GREENLINE technology
  • a double pane set Ug=1,1 W / m2K 4/16/4 with aluminium frames
  • MACO MULTI MATIC KS Austrian fittings
  • safe aluminium handles
  • thermal transmittance factor of Uf=1,3 W / m2K
  • thermal transmittance factor of the reference window 1230 x 1480 Uw=1,30 W / m2K
  • environment-friendly due to the use of recyclable materials
  • an undersill board facilitating the assembly of interior and exterior windowsills
  • all gaskets in the colour black


Rehau Synego System

If you place importance in a warm and comfortable interior and cost saving and you want to keep the heat generated inside your house, REDAN SYNEGO windows will be the right choice. Thanks to new SYNEGO windows, your house will become a heaven of peace, warmth and safety. In comparison with the current window standard, SYNEGO will provide up to 50% better thermal insulation, which will significantly reduce heating bills. Other characteristics of the SYNEGO system are:

  • up to 20 times less noise
  • up to 10 times higher anti-burglary protection
  • the possibility of obtaining Uw = 0,66 W/m2K for the reference window when using a 4-pane set of Ug=0,4 W/m2K
  • applying a middle gasket – an additional improvement to thermal insulation and better rain- and wind protection
  • sound resistance: up to Rw,p = 46 dB class
  • burglary protection: up to RC3 class
  • a significant reduction of carbon dioxide emission through better thermal insulation
  • the option to construct windows of large dimensions owing to enhanced static properties

Technical parameters:

  • REHAU SYNEGO profile
  • triple gasket MD system
  • a very smooth profile surface thanks to HIGH DEFINITION FINISHING technology
  • a 7-chamber system with a 80 mm installation depth
  • low 117 mm sills – to allow for more sunlight in rooms
  • a triple pane set of Ug=0,5 W/m2K
  • higher security thanks to MACO MULTI MATIC Austrian fittings with an anti-burglary mount, sash lifter and incorrect opening blocker
  • handles made with MACO SOUL technology
  • thermal transmittance factor of Uf=0,94 W/m2K
  • thermal transmittance factor for the reference window 1230 x 1480 Uw=0,72 W/m2K
  • higher structure rigidity – veneered windows include a 2 mm thick reinforcement
  • an additional gasket in the glazing chamber that improves thermal properties
  • a “golden line” that is unique to REDAN windows
  • a “warm” undersill board with a gasket making mounting interior and exterior windowsills easier
  • all gaskets in the colour grey


Ovlo Classic

Based on the OVLO window construction system, it’s superior due to its attractive parameters. The OVLO CLASSIC window has a sash forming a gentle line which gives it an alluring look. A 6-chamber profile with a 80 mm wide installation provides excellent thermal parameters.

Technical parameters:

  • a solid profile with an enhanced rigidity guarantees more freedom in planning the window’s structure
  • an immaculate whiteness and a brilliant polish are achieved through using high-end PVC
  • delicate curves give the profile a modern and elegant look
  • resistant to dirt and atmospheric conditions, easy to clean
  • neutral glass that does not produce the so-called “dirty curtain” effect
  • by using a triple pane set with a factor of U = 0.7 Wm2K, you can save even up to 20% on heating costs
  • gaskets with EPDM guarantee adequate air-tightness
