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