4700-Series ThermoPlus™ Tilt & Turn


EuroLine’s ThermoPlus windows help reduce CO2 emissions and save you money.

ThermoPlus comes with the new generation GENEO® window profiles with a depth of 86 mm, combining the benefits of uPVC and fibreglass in a new hybrid RAU-FIPRO® material.

RAU-FIPRO forms a continuous, weldable reinforcement that provides superior inner strength. The outer layer of high-grade uPVC forms a smooth, low-maintenance, easy-to-clean, and pore-free surface that only high-grade vinyl can provide. Both layers are inseparably fused during the monolithic structure. RAU-FIPRO is an innovative composite material formulation created by REHAU, based on its extensive experience with composite materials for aircrafts and Formula 1® race cars, and in the design and extrusion of high-performance uPVC window profiles. The result is a window profile with high stability, torsion stiffness, and structural properties – all characteristics not formerly possible in vinyl window systems without the addition of steel reinforcements.

The ThermoPlus window system combines the GENEO profiles with multi-point locking ROTO NT hardware, protected by a RotoSil® nano coated surface, where the base steel is galvanized and passivated with nano particles, then optically sealed. This tensions the surface, providing excellent protection against corrosion, while forming a self-healing skin for small scratches. The coating technology is environmentally safe because it is free of Chromium (VI) compounds and other heavy metals.

Add high-performance glazing and you get the most durable, versatile and energy-efficient window system in its class. With its sophisticated six-chamber profiles, robust and durable hardware, and high-performance glazing, the ThermoPlus window system forms a virtually impenetrable barrier for anything mother nature may throw at it, whether it is a single family house or a high rise building. The perfect way to create peace-of-mind within a comfortable environment.


4700-series windows feature tilt & turn operation with multi-point locking hardware – because what is more important than security for you and your family?

One easy-to-operate handle moves the multi-point locking hardware into place and locks the window on all sides for higher security and a tighter seal.

With the handle in the “turn” position, the sash turns inwards at the side. This position allows for easy cleaning from the interior, rapid cross-ventilation, and quick emergency egress.

With the handle in the “tilt” position, the sash tilts inwards at the top, providing draft- free, secure ventilation.



By combining the six-chamber vinyl-fibreglass hybrid frame with the optional foam inserts and triple-pane insulating glazing, the 4700-series window system can achieve the thermal performance needed for a Passive House design. See ThermoPlus PHC for more information.




  • Made from REHAU’s innovative vinyl-fibreglass material RAU-FIPRO®.
    • This combination of uPVC and fibreglass provides the benefit of both materials:
      Like vinyl, its surface is smooth and pore-free, preventing the growth of mould and mildew. It can be extruded in a multi-chamber design with the corners fusion-welded to guarantee a permanent and leak-free connection.
      Its hybrid core provides the high stability, torsion stiffness, and static properties of fibreglass. What’s more, it is low maintenance, easy to clean, and has a low thermal expansion ratio.
  • Outstanding light and weather resistance as well as colour durability
    • After 10,000 hours of exposure in the Weather-Ometer, no change in colour is discernible, the notch impact strength is scarcely altered, and there is no visible change in surface gloss.
  • High-impact resistant
    • Essential during transportation and installation when window frames are subjected to bending and exposure to low external temperatures in winter. Under these conditions, cracking is much less likely with uPVC than with regular PVC.
  • No plasticizers or lead
    • 100% recyclable (where facilities exist)
    • Won’t make your family sick
  • Fusion-welded corners
    • Corners are fusion welded for strength and to prevent air and water infiltration, as can happen with windows that are connected mechanically (e.g. fibreglass or aluminum windows).


  • 6-chamber design
    • Each chamber acts as a thermal break, providing insulation and high thermal performance.
  • Thicker walls
    • Give the doors more strength overall, and specifically in the corners, where more material means a better, stronger weld.
  • Smooth surface for easy cleaning
  • Extruded profiles are available in white only


Because of the strength provided by the fibreglass in the profiles, most windows do not require additional reinforcement.

This makes ThermoPlus window lighter compared to other high-quality, steel-reinforced windows, making installation easier and faster.

Larger windows and doors are still reinforced with roll-formed galvanized steel that is fastened to the profiles to provide additional strength.



With its three surrounding seals – two compression gaskets and one centre seal – the GENEO® window profile offers the best possible insulation characteristics.

The highly elastic, stress-resistant flexible PVC seal material guarantees a long service life.


  • 4700-components-locking-pointsMulti-point locking hardware by ROTO FRANK
    • Number of locking points increases with door size
    • Seals out harsh weather
    • Makes it virtually impossible for intruders to break into your home through the frame
  • RotoSil® Nano coating
    • Offers the highest available surface protection. Through galvanizing, chromating, and additional sealing, the hardware becomes extremely scratch and corrosion resistant. If the surface is lightly scratched, the coating “heals” itself, continuing to provide protection against corrosion.
  • Single-handle operation
    • All locking points are simultaneously operated simply by the turn of a single handle
    • Makes the door easy to operate even for children and people with limited mobility.



  • Comes standard with:
    • 24mm dual-pane insulated glass unit (IGU)
    • One coating of LoE 270
    • Argon gas fill
    • Warm edge SuperSpacer®
  • Available with 44mm triple pane IGU


  • The LoE soft coating improves energy efficiency by reflecting radiant heat from the sun back out in the summer, keeping the interior of the house cool, and reflecting radiant heat from heating back inside in the winter, resulting in less heating being needed. In addition, the LoE coating also reduces UV transmittance, which helps save your furniture from fading.
  • Because argon gas is heavier than air, it is a better insulator. Using argon gas between the glass panes results in less heat transfer, which means less moisture and ice buildup on the glass.
  • 4700-components-spacerThe spacer that is used in the IGU also plays a very important role in how it performs. Metal spacers not only transfer much more heat, they also are more likely to fail, allowing the argon gas to escape, moisture to enter, and mold to grow. This is the reason why all EuroLine windows have a SuperSpacer – a warm edge technology spacer that significantly improves glass performance. After a 5-year high-humidity test it was found that 99% of the argon was retained.


  • Since EuroLine does not use glazing tape and dry glazes all units, glass replacement is fast and easy if it ever becomes necessary.
  • In standard applications IGUs are glazed from the interior for security
