AluClip window profile

Similar to the AluClip system, the AluClip Pro window system has been designed with an aluminum profile bonded to the uPVC profile. The aluminum then takes over a significant part of the load-bearing capacity, and the window sash no longer needs internal steel reinforcement in the sash and frame.

It combines the advantages of both materials in one structural element. On the outside, the aluminum cladding offers almost limitless possibilities in color design, whilst on the inside, uPVC profiles ensure low maintenance, high dimensional stability, and reliable functionality.

Different U-values are possible depending on the frame/sash combination, glass, and spacer insert. Contact us for more details.

Features and Benefits

  • Extraordinary thermal insulation compared with aluminum windows. Typical U-values are between 0.21 - 0.23 Btu/hr-sq ft-°F

  • Steel-reinforced chambers for effective protection against unwanted intruders.

  • Excellent sound reduction properties - Up to 46 dB.

  • Unlimited choice of RAL colors and finishing techniques such as anodizing and powder coating.

  • Available in Parallel or Tilt Turn opening for maximum ventilation and security.

Color Options and Finishes

Aluminum covers are ideal for individual designs. They come in countless RAL colors and diverse finishing options like powder or anodized coatings. Contact us for more details.

Technical Drawings

We provide a full range of technical drawings for every project and work closely with the architect to overcome any obstacles during the design phase. We are on hand 24/7 if you need to use our expertise.

All of our technical drawings are shown in mm for precision.  If you prefer to receive drawings in inches, our team of designers and planners will happily make the conversion for you. 

Every window we manufacture is designed from scratch to suit the needs of the building, so the dimensions, glazing, chambers, and steel reinforcements shown in this image may be different depending on your project specification.
