Bradworthy Bi Folds use Western Red Cedar to manufacture all doors and jambs, with Merbau sills. We specialise in Western Red Cedar because it shrinks and contracts less than other timbers resulting in less surface cracks when painted or stained. Also with bi-folds it is imperative that the doors remain stable to ensure they open and shut properly.

Western Red Cedar is highly suitable for external applications because of its light weight, high dimensional stability and high durability. Its light weight is due to its low density which makes it easier to work with, allows for deeper penetration of stain finishes (thus extending the life of the finish) and providing it with the highest insulating value of all commonly used softwoods.
Although it has a low density, its strength as a wood is equal to or greater than other softwoods commonly used in Australia, since characteristics such as knots, gum veins and moisture levels are significantly reduced. With a durability rating of class 2, Western Red Cedar is recognised as being very resistant to decay and is also known to be highly resistant to termite attack.
Western Red Cedar has an exceptionally high dimensional stability rating which is unequalled by any other timber used commercially in Australia.
All timbers tend to absorb moisture from the surrounding atmosphere until equilibrium has been reached. As a result, some movement such as swelling, cupping, twisting, distortion and loosening of fastenings can occur. In Western Red Cedar the movement is minimal thereby prolonging the life of the structure and any paint/stain coatings.
Western Red Cedar (Thuja Plicata)
According to the Native Indians of the west coast of North America the Western Red Cedar was ‘the tree of life’. They used its stringy roots, shreddy bark and fragrant timber in everyday life.
Today, Western Red Cedar is used in homes for its exceptional durability, light weight, beauty and texture.
