System ALT150 of hidden fastening of natural stone

Natural stone is suitable for exterior cladding that seeks to integrate design with the surrounding environment. Always used in an architecture, it is timeless  material and offers exclusivity in beauty, comfort and efficiency that allows it to be enjoyed for a long time in exterior cladding gaining value and beauty over the time. It benefits as an acoustic insulation as well as in terms of energy efficiency and protection from heat in summer and cold in winter.Natural stone is ideal for sustainable constructions.

System ALT150 of Ventilated Facade is an exterior closing system that allows laying of a natural stone separated from thermal insulation with a help of a supporting structure. This separation allows an easy going of air between the tile and the facade, which achieves optimal acoustic and thermal insulation as well as effective protection against atmospheric agents.

Advantages of ALT150 System for ventilated facade :

  • Save up to 30% of electricity consumption.
  • It offers excellent acoustic and thermal insulation.
  • Sustainability and energy efficiency.
  • Reduces installation times.
  • Maintenance time is reduced. It is easier to unpin a part from a bracket than to tear it off a wall.  On ventilated facades the pieces are fitted using hooks or staples and not gripping materials or adhesives.
  • The joints between the pieces that make up the exterior façade reduce the problems derived from expansion.
  • It improves a stability of the building and its useful life by reducing the expansions and contractions suffered by the materials.
  • It reduces the insulation needs in the interior achieving a greater useful surface of the house since these interior systems may require a greater thickness.
  • Aesthetic benefits since they allow the use of design and a greater range of materials and colors.
