Can Maple Be Used As Siding?

Decay Resistance

• The heartwood of some tree species contains compounds of oils, resins, tannins and polyphenols called extractives. These chemicals are deadly to most decay-producing bacteria and may repel termites. In some wood, membranes called tyloses block the vascular structure of the wood, making it impermeable to water. Because decay-producing bacteria prefer a moist environment, they are less likely to thrive in heartwood where tyloses are present. Wood that contains extractives or tyloses, or a combination of both, is resistant to decay and insect damage and is well-suited for use as exterior siding.

Outdoor Wood

• Thanks to natural decay resistance, several kinds of wood are good choices for use in outdoor applications such as exterior siding. The extractives in cedar and redwood give these woods their distinctive aromas and also help the wood stand up well to the rigors of exterior use. Black locust and white oak also are resistant to excessive weathering, although they are less commonly used for siding than are cedar or redwood. Maple, however, is not substantially endowed with either extractives or tyloses and doesn't hold up to the elements nearly as well as other woods.

Cedar and Redwood Siding

• Both cedar and redwood are commonly used in the manufacture of exterior siding. Both woods may be used outside with minimal finishing, and they will stand up well to weather, sun and insects. Natural decay resistance develops in the mature heartwood of the trees, as opposed to the younger sapwood, so only the best grades of heartwood lumber should be used for siding. When properly maintained, siding made from these woods can last for 30 years or more.

Maple Uses

• Maple is a fine-grained hardwood that often has appealing figures and patterns in its grain. It is durable and dense, and it holds up to heavy use. Its natural color is light and attractive. It stains well and may be finished to mimic other woods, such as cherry. Although maple is not a good choice for exterior uses, its characteristics make it a popular option for sturdy and attractive indoor furniture.
