Alaskan Yellow Cedar

Cupressus nootkatensis or Chamaecyparis nootkatensis) aka Nootka Cypress, Yellow Cypress and Alaska Cypress Alaska yellow-cedar is a coastal, high-elevation, tree species. Despite its name, it is actually a cypress. It is a medium-sized (rarely over 40 meters tall) evergreen. It is one of the slowest growing but most valuable conifers owing to the unique color, texture, and durability of its wood. Alaskan Yellow Cedar is a softwood that is distinctly different from other cedars in its yellow color, dimensional stability, extreme strength and hardness.

Bevel

Board and Batten aka “Board and Batt”

CDX plywood is typically used as wall sheathing and underneath roofing felt and shingles. CDX plywood is moisture resistant but cannot be exposed to water or weather for long periods of time. It is economical because it is made with lower grade material as compared to exterior grade plywood. Consequently, CDX plywood will include some knots and shallow holes in its face and back. To eliminate those imperfections, CDX plywood usually contains a number of characteristic “football patches.”

Eastern White Cedar Shingles

(Thuja occidentalis) is an arborvitae of eastern North America, which is also called white cedar. It is a small-sized evergreen, averaging 12 meters in height. This rot and insect-resistant wood is used principally for products in contact with water and soil such as rustic fencing, posts and saunas. Other important products include cabin logs, lumber, poles and shingles

Extractive Bleeding

These reddish brown stains may appear in several forms. “Diffused” discoloration can result from rain or dew penetration through the finish whereas “rundown” discoloration typically results when water collects on an unfinished surface, such as the back of siding or unprimed ends of boards. Water-based finishes can also dissolve extractives and cause discoloration as a result.

(Calocedrus decurrens) aka California White Cedar is native to the mountains of the far west. The natural range extends from near the Columbia River in Oregon south to northern Baja California in Mexico and east to western Nevada. The heartwood is a light to medium reddish brown, soft, light, fine grained, and pleasantly aromatic. The wood contains substances that retard decay and repel moths. The wood is traditionally used for cedar chests, siding, interior paneling, shingles, decking, pencils, and fence posts.
