STRATOSFERA is a thermal skim coat based on water-based acrylic resins and non-absorbent hollow recycled glass microspheres. It can be applied on a variety of both absorbent and non-absorbent substrates thanks to the high adhesion and quality of the resins used. It can be used to solve the problem of micro-cracks in the substrates, thanks to its flexibility it compensates for the movements of the laying substrate, it has good permeability to water vapor and is impermeable to driving water, it is used both indoors and outdoors pigmentable with any color metric system on the market. It is used to eliminate the effect of thermal bridges and consequently the formation of condensation and mould, it optimizes the energy performance of buildings thanks to its insulating power due to the air present in the hollow spheres and absorbents, it can also be used in contact with food.
