Charred board for the facade is on the market. Here's how it looks

The Suntan Wood catalog features samples of facade boards in various depths and even firing with color tinting options. The width of the boards is 95, 120, 140 mm.

Firing protects the wood against fungus and decay. But the manufacturer warns against excessive exposure to sunlight. So you either have to put up with the gradual discoloration of dark samples, or use the board on the facade in fragmented, shaded areas.

The board does not stain or smell. Requires a protective coating every 5–7 years. Claims to last up to 80 years.

Here are examples of the use of burnt wood on facades.
