Today there are two different insulation systems available on the market: internal and external. Polymeric foams are the most popular external foams used in both cases due to the fact that they are easy and quick to apply and do not take up space internally.
Panels of polystyrene are fixed to the wall with mortar and anchors to prevent any wind damage. A layer of glass fibres is then added to protect the polymeric foams from any possible impact. This is followed by the application of damp proofing and finally a layer of textured plaster to the external wall insulation systems. This last layer is used purely for aesthetic purposes.
There are several main goals in this project, the first of which is to extend the life of this new generation of ETICS.
Another goal is to reduce the size of the polymeric cells to nanoscale in order to decrease the thermal conductivity of the polystyrene board. This means, with small cells, it will be possible to increase the number of cells and at the same time reduce the thermal conductivity by maintaining or decreasing the total thickness. Finally, by using less polystyrene the results of the LCA will be improved.
All the tests to certify that the final product is ready to sell are regulated by standards. Each test corresponds to a specific standard. Standards provide all the necessary parameters to follow the protocol of the test according to requirements. They are used for technical tests based on the mechanical, thermal, fire resistance and permeability properties of the materials and also for life cycle analysis and electrical regulations.
