Tapersawn Yellow Cedar Shakes

Yellow Cedar, also known as Alaskan Yellow Cedar or Western Cypress Tapersawn Shakes are sawn on both sides giving it a look similar to a sawn shingle but with a thicker appearance, Tapersawn Shakes are known for their smooth uniform look compared to the rustic look of hand-split shakes. The added thickness enables it to be applied as a shake (2 ply with paper/felt interlay) resulting in lower application costs.
