Using AITHON PV33 is possible to upgrade the fire resistance class of historical buildings and protect in the same time their ancient beauty saving the original timber frame.
Furthermore AITHON PV33 reduces the environmental impact of the restoration works.
In new buildings fire resistance is achieved oversizing timber beams and columns to compensate the wood thickness which is carbonized in case of fire.
Reducing the carbonization speed, AITHON PV33 allows to reduce timber oversizing, saving cost and weight of the timber frame.
