Siberian Larch has a stunning colouring and texture, starting life as a pale yellow/golden brown. Larch is also unique in that it features the shapes and patterns of its growth rings.
External cladding applications.
Softwood timber cladding.
Features and benefits:
Moisture movement:
Wood’s moisture content will change relative to its surroundings. Different species have different degrees of movement and this must be accounted for in cladding design.
Good design and installation practice will help minimize the effects of moisture:
