Bevel Siding

Western Red Cedar Bevel Siding Cape CodWestern Red Cedar bevel siding is the most widely-used siding type. It is produced by resawing lumber at an angle to produce two pieces thicker on one edge than the other. The manufacturing process results in pieces with one face saw textured. The other face is smooth or saw textured depending on the grade and customer preference. Bevel siding is installed horizontally and gives an attractive shadow line which varies with the thickness of siding selected.

Grades

Bevel siding is available in clear and knotty grades. Clear siding gives premium quality appearance and is ideal for prestigious, upmarket applications. Knotty siding has warmth and casual charm and is ideal for homes, cottages, club-houses and applications where a rustic appearance is desired.

Finger-Joined Bevel

Western Red Cedar Bevel Siding Cape CodWRCLA members also produce finger-joined bevel siding in clear and knotty grades. The precision-fitted joins are virtually invisible and stronger than the surrounding fiber. Finger-joined bevel siding is available in lengths up to 16 feet and provides the handsome appearance and all-weather performance of premium cedar siding. Builders appreciate both the convenient long length tally and the speed and ease of installation with fewer field joins.
