Sapa Facade – 4150 SX High Insulated


Sapa Facade – 4150 SX  High Insulated

The 4150 SX facade system consists of 50 mm wide insulated aluminium profiles. Our newly developed insulating thermal break together with the inside gasket, provides good insulation capacity (so-called High Insulated). 

The mullions are designed so as to ensure stability under the dimensioning loads and are joined together with hidden joints. The system can be easily complemented with opening units. The U value of a facade must be calculated for the entire facade, see the right hand menu.

  • High insulated profiles
  • Several types of mullion and transoms. Rectangular (profile depth 35-300 mm), I- and T-shaped profiles give a lot of freedom in interior design.
  • Wide range of decorative caps for exterior design.

Opening units

The window frames are specially adapted to the glass rebate of the facade system for simple installation. The windows in the 1074 SX window system are available as tilt and turn, bottom- hung, top-hung and side-hung, inward opening units.

The 2074 door system includes inward and outward opening single or double leaf doors with frame profiles that are specially adapted to the glass rebate of the facade system for simple installation.

Facade additions

Opinions differ among designers on how the outside joints of a glass facade should be shaped. We have two different decorative profile systems: Add and Expressive.

  • Add, offers a design concept with its visible fastening elements and characteristic groove. The add cap is also able to support solar shading elements, lightning conductors, down pipes, rain gutters, signboards and lighting.
  • Expressive, gives the designer more freedom in the play of light and shadow on the facade. It is also possible to design one’s own decorative profiles if needed.
