A shelter against fire

At ambient temperature Aithon PV 33 provides a stable, wax-like finish which preserves the natural beauty of wood. But in a fire the varnish softens and swells, forming a thick, high insulative layer which prevents the spread of flame and protects the wood from charring.


Aithon PV33 is suitable for use in public buildings, schools, housing, shopping centres, restaurants, banks, churches and for walls and ceilings in escape routes where timber or wood derivatives are used.
