Thermal and acoustic insulation of double-sided vertical cladding

The implementation of a regulatory framework regulates the constructive quality of the buildings, in relation to their exterior insulation, requires greater thermal and acoustic insulation, as well as greater protection from humidity and fire.

The use of thermal and acoustic insulation based on cement mortar and mineral wool in double-sided cladding adequately responds to several of the documents that comprise the current Technical Construction Code (CTE).

Preliminary analysis

This insulation system is applied on the back of the brick masonry construction.

It has the following advantages, among others:

  • It guarantees a constant insulation thickness throughout the surface of the façade.
  • It increases the thermal resistance of the cladding.
  • It positively influences thermal bridge rupture.
  • It reduces energy demand, both in winter and in summer.
  • It eliminates the risk of superficial and interstitial condensation.
  • It increases thermal comfort, avoiding the cold or hot wall effect.

Technical considerations

This system, composed of the waterproof adhesive mortar GECOL Lana mineral and a mineral wool insulator, is characterized by its simple onsite installation, in addition to easy and fast application.

As in cladding construction work, we must previously adapt the substrate.

To this end, we must follow these steps:

  • Firstly, the substrate must be correctly cleaned in order to ensure that it is free from dust, surface grouting, residue and micro-organisms.
  • Next, the adhesive mortar GECOL Lana mineral is applied.
  • The mineral wool panels are installed over the fresh mortar, ensuring the correct union of these to the adhesive mortar.
  • Once the insulating mineral wool panels are fixed, the paneled interior of the wall is raised.
