Cedar

Eastern white cedar is a slow-growing conifer, native to northeastern North America. Averaging a height of 15 to 20 metres and a diameter ranging from 40 to 90 centimetres, it can reach over 20 metres at maturity with a diameter of 120 to 150 centimetres. It has remarkable longevity and some specimens live to be 800 years old. Its wood is stable, finely textured and extremely long lasting. It offers exceptional natural resistance to insects and decay, resulting in excellent durability. Its structure makes it a very good insulating material when it comes to sound and heat. Cedar does not require any preservatives or special maintenance. It is a natural alternative to treated wood. Its pleasant fragrance makes it highly prized for interior woodwork.
