Facade insulation systems on flat substructures

Facade insulation systems on flat substructures apply to new and old buildings in solid timber and masonry construction. PAVATEX offers multilayered insulation systems for both classic timber construction with double timber frame construction and with PAVAWALL.

Facade insulation systems on flat substructures

  • Complete system consisting of insulation, weather protection and windproofing.
  • Cost and time savings in renovation, as the old facade can remain completely intact.
  • Outstanding sound insulation, because there is no resonance developed in the insulation layer.

Timber frame construction system with PAVAFLEX and DIFFUTHERM

The timber frame construction system with PAVAFLEX and DIFFUTHERM enables insulation of masonry and solid wood structures in classic timber construction.

Compact system with PAVAWALL

In the PAVAWALL compact system, the insulation is glued to the substructure in a single layer and, in addition, then fixed using special insulation anchors.

Installing PAVAFLEX and DIFFUTHERM

Mounting of the substructure

Mounting of the substructure

In the first step, installation is carried out directly on the external wall. In renovation of buildings with rendered external thermal insulation, the existing old facade can remain entirely intact and the new timber frame structure can be built directly onto it.

Next, the spaces in the substructure are insulated by filling with void-free PAVAFLEX.

DIFFUTHERM insulation

The DIFFUTHERM insulation boards can be fixed directly to the studs. Finally, the DIFFUTHERM is rendered in accordance with the render manufacturer’s specifications. A mineral-based render system consisting of base coat, reinforcement mesh and finish render must be used.

Processing PAVAWALL

Bonding of PAVAWALL insulation

Bonding of PAVAWALL insulation

Before beginning work, ensure that the substructure is able to take a load, and is dry and free of grease and dust. Apply adhesive to one side of the PAVAWALL insulation boards in the form of a bead around the edges and in the centre in accordance with the requirements of the system provider, and press against the facade.

Control of dimensional accuracy

Control of dimensional accuracy

During board installation, the facade must be constantly checked for deviations from plumb.

Fixing of the boards

Fixing of the boards

In addition to bonding, the PAVAWALL insulation boards must be fixed mechanically. Special insulation anchors suitable for the substructure must be used. Finally, the PAVAWALL is rendered in accordance with the render manufacturer’s specifications. A mineral-based render system consisting of base coat, reinforcement mesh and finish render must be used.
