Project Tilia

Type of works performed by Alu Alprem:

  • Façade glazing
  • Windows
  • Fire-resistant doors
  • Ventilated façade
  • Cladding panel from aluminum sheet


  • 1,500 m²
  • Ucw < 0.8 W/m²K
  • Uw < 1.0 W/m²K

We renovated a business building’s entire façade in the center of Novo Mesto.

The new front of the building is a combination of a double-glazed façade, Kerrock panels, a ventilation layer, and 20 cm of insulation. The building envelope made of glass accumulates heat that is retained by state-of-the-art triple-glazed aluminum windows with Uw < 1.0 W/m²K. Building elements were built according to RAL guidelines. We submitted a certificate to the investor for this project. Alu Alprem was responsible for the entire renovation. From designing the façade to its execution. At the end of renovation, the business building, Tilia in Novo Mesto, had a large glass façade with the lowest heat transmittance in Slovenia at the time.
