Cubic metres versus tonnes

We sell our logs by the cubic metre rather than by the tonne. We do this because the volume of logs in a tonne would vary greatly depending on the moisture content of the logs and the density of the wood. If, for example, the logs were freshly cut you would receive a lot less than if you were to buy barn dried logs and although we only use hardwood timber, the density of the wood will vary according to the different tree species. So, all in all, it would make pricing our logs very difficult if we were to sell by the tonne! Besides this, a builder's tonne bag will only hold about 0.7 of a cubic metre of logs and weigh considerably less than a tonne!


A cubic metre is the industry standard for measuring the volume of a 'load' of firewood and is a much easier and fairer method of measurement than weight.


How do you measure a cubic metre?

We tip the logs into one of our specially designed tipper trucks. We have two delivery vehicles one holds 3 cubic metres and the other 4 cubic metres and both trucks are divided into one cubic metre sections using specially installed gates, as shown in the photos below. Therefore, we know that one full and level section of the truck is equivalent to one cubic metre.


Why do you sell by a cubic metre of loose logs rather than stacked logs?

After we cut and split the timber into logs, the logs go into our drying barns until they're fully seasoned and have reached a moisture content of 20% or below. The drying barns allow maximum ventilation and the gaps between the loose logs allow the air to circulate well in order to further aid the drying process. Our entire processing, drying and delivery process is based on the logs being loose.
