External wall insulation in timber construction

For external walls in timber construction, the weather protection that is formed by the actual façade and the moisture control layer behind it, take on special importance. For ventilated and rendered facades, PAVATEX offers insulation systems optimally adapted to the needs of timber construction.

External wall insulation in timber construction

  • Complete system consisting of insulation, weather protection and windproofing. 
  • Outstanding sound insulation thanks to fibrous board structure and high insulation mass. 
  • For a building shell free of thermal bridges. 
  • Permeable but simultaneously airtight and windproof wall construction. 
  • Fire resistance class up to F 90-B and REI 90, respectively.

The voids in the timber frame construction are insulated with PAVAFLEX. See “Between rafter insulation system” chapter for installation information.

Installation of the PAVATEX DB 3.5 vapour control membrane

Installation of the PAVATEX DB 3.5 vapour control membrane

The PAVATEX DB 3.5 vapour control membrane is installed internally. Installation and all connection work must be carried out in accordance with the PAVATEX sealing brochure.

Installation of the insulation boards

Installation of the insulation boards

PAVATHERM-PLUS or DIFFUTHERM is installed on the outside of the external wall studs. Either insulation anchors or wide crown staples may be used for fixing.

Installation of the clad facade or external render system

Installation of the clad facade or external render system

The wall insulated with PAVATHERM-PLUS is clad with a facade system in wood, stone, sheet metal or similar. DIFFUTHERM must be rendered with a mineral-based render system. Attention must be paid to the application details of the relevant rendering contractors.
