The Multipor internal insulation system WI enables the energy efficiency of buildings to be improved from the inside and is particularly suitable for old and listed buildings where the façade is to remain unchanged.

At the heart of the system is the Multipor TIPwall M4 mineral insulation board. It is made from natural and mineral-based raw materials – sand, lime, cement and water – and is combined with specially matched system components to form an internal insulation solution.

The insulation boards are vapour-permeable, capillary-active and non-combustible (building material class A1). A vapour barrier is not required. The system has been tested for harmful substances. It provides a pleasant, healthy indoor climate and structural safety.

Quality features are documented by various independent certifications and accreditations, including natureplus®, eco-INSTITUT, Sentinel Holding Institut, QNG-ready, EPD and VOC Class A+.
