The internal retrofitting system is composed of the following layers
- Clay reinforcement mortar
- ISOBIO rigid panels
- CSB panels
- Clay plaster
As the first layer, a clay reinforcement mortar is used to attach the ISOBIO rigid panels to the exiting wall.
When the clay reinforcement mortar has acquired its mechanical properties after its curing time, the CSB panels are mechanically or adhesively joined to the ISOBIO rigid panels and placed in a vertical disposition. Finally a clay plaster produced by CLAYTEC is applied as the finishing coating. This plaster is made of earthen clay, hemp powder, pumice and sand.
In order to reduce the interior dimensions as less as possible, in internal retrofitting activity it have been decided to stuck all the panels to the existing wall with a clay reinforcement mortar avoiding the extra space that a frame would take. The main function of the clay reinforcement mortar is to fix ISOBIO rigid panels to the existing wall that will be retrofitted.
The combination between the ISOBIO rigid panels and the CSB panels helps to maintain the system’s structure and to increase its thermal insulation properties. Moreover, it acts as a moisture buffering layer, providing the system the protection it needs from any moisture-based damages.
The clay Plaster is an easy to use material that acts as a fire retardant while possessing a very stable moisture buffering effect. Moreover, it provides the required esthetical finishing to the interior of the building.
It will aid in reducing the energy consumption needed for air conditioning housing. It will also protect the building from moisture-based damages and possible outbreaks due to temperature changes. All these make the buildings highly energy efficient while providing an optimal level of comfort for residents at any time of the year.
