KATTO ventilation and cladding boards
Protection of the house frame
Pre-treated KATTO ventilation and cladding boards protect the house frame against moisture. The ventilation and cladding boards are painted on all four sides with a wood preservative to protect the wood against moulding and blue staining. The standard colour of the wood protector is dark grey. On request we can also supply colourless, yellow, or light grey colour.
