WESTERN RED CEDAR BENEFITS
- DURABILITY–Western red cedar is a naturally durable softwood that creates extractives (Thujaplicans and Phenolics) that ward off decay caused by insects, water infiltration, and fungi. The extractives increase with age leading to a longer lasting product life cycle–especially in exterior applications.
- DIMENSIONAL STABILITY–WRC has a very low shrinkage factor and is largely superior to all other coniferous softwoods in its resistance to warping, checking, and twisting.
- THERMAL CONDUCTIVITY–WRC’s low density gives it a high thermal insulating value because it contains a high proportion of cell cavities. In dry wood, these cavities are filled with air which is one of the best known thermal insulators. The R value is 1.35″ (34mm) of thickness.
- FIRE RESISTANCE–reSAWN’s CHARRED CEDAR has a Flame Spread Index of 40 and a Smoke Developed Index of 140 to give it a Class B Rating. CHARRED CEDAR can be fire treated to Class A for interior projects.
