AluClip window profile

This aluminum add-on system is the perfect solution for people who want high-tech look windows. The aluminum-facing shells are press-fitted to the uPVC profiles with a clip mechanism.


Aluminum is elegant, highly weatherproof, extremely stable, and available in a wide range of colors. uPVC provides optimum heat and sound insulation, plus high functional reliability. This allows you to enjoy the advantages of both materials.

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

Features and Benefits

  • Extraordinary thermal insulation compared with aluminum windows. Typical U-values are between 0.23 - 0.25 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.
