White cedar interior siding

SIDEX white cedar siding is proudly sourced in Eastern Canada (Quebec and the Maritimes) and processed at our Magog plant.

Grade: knotty or clear?
Two criteria will guide your decision. First, visually, the clear cedar siding offers a much more refined and modern look than the knotty cedar siding. However, its cost is much higher, as each board is carefully selected. Your budget could therefore impact your decision.

As its color is more uniform than red cedar, the opaque coating is a better fit. All types of coatings can therefore be applied to white cedar. The frequency of maintenance, referred as the addition of a new coat of stain, and the visibility of the wood grain will guide your decision as to the ideal type of coating for your project.

Advantages and disadvantages
White cedar is especially chosen for its ecological aspect. As it is sourced in eastern Canada, it has less distance to travel than red cedar, which comes from western Canada, before being processed and installed. Its great stability and resistance to decay make it a great choice for siding.

However, due to the natural characteristics of the tree itself (diameter and geometry), it offers fewer possibilities in widths and lengths (ratios) than red cedar. The choice of profiles and widths are therefore more limited than the other species.


Cedars offer many advantages if you are looking for a lasting quality that easily spans the years. As they are rot-proof and insect repellents, they are more resistant to bad weather and threats from the environment.

Cedars are also more physically stable, making them less likely to twist or crack over time. The variation in humidity and outside temperature causes what is called the dimensional variation of the wood, which causes it to expand and shrink slightly over the seasons. The composition of the cedar planks ensures that this dimensional variation is kept to a minimum.

The tannins that give these interesting benefits to the cedar siding are however the same that you must know how to control during the coating process to limit the counterparts. This is why SIDEX products are processed in a controlled environment from start to finish and why our company has developed this expertise in the last 15 years.
