Niangon
Heritiera utilis
- Primary hardwood
Niangon is a reddish-brown hardwood with a coarse texture and a characteristic greasy or waxy feel from natural resin content. It is durable and stable enough for exterior joinery, and the resin gives good weather resistance, though it can interfere with gluing and finishing unless surfaces are degreased. Commonly used for windows, doors, cladding and boat work.
