What is the density of timber?

Density of timber is measured in kilograms per cubic metre (kg/m3). It is a measure of mass per unit volume. Timber density is affected by moisture in the environment.

Is C16 timber strong?

Whilst C16 graded timber is strong enough for some applications such as wall plates, studwork, rafters, joists etc… It’s a premium piece of timber that can handle higher loads and wider spans.

Is C24 heavier than C16?

C24 timber is approximately 50% stronger than C16 timber, this means it is more appropriate for longer spans or heavier loads. A C24 joist can bear more weight than a C16 joist thanks to the increase strength and durability within.

What is the C rating on timber?

There is a set primarily for softwoods which begin with the letter C (e.g. C16 and C24) and a set for hardwoods which begin with the letter D (e.g.D24 and D30). It is sometimes said (e.g. 1, 2, 3) that the C stands for Coniferous and D stands for Deciduous.

What type of wood is the most dense?

Does all wood float?

How does C16 grading affect the strength of wood?

C16 graded timber allows for a number of defects that may reduce the overall strength of the wood, such as grain deviations and wanes, as well as an unlimited amount of superficial defects that do not affect the strength of the wood, such as blue sap stains and the like.

Where is C16 timber made in the UK?

C16 timber is generally made within the UK, keeping costs down, and is of slightly poorer quality with some defects, but is still strong and resilient, making it useful for strength and load-bearing.
