Firewood Journey

The team at Treeline take huge care and use years of experience to produce and supply the best firewood to our many customers across the Scottish Borders, Edinburgh, and the Lothians.  We aim to supply a dry, consistent and reliable product from what is a very varied and natural material.  Through the woodland management arm of our business we are able to do this by having control of the whole supply chain, from planting and growing the trees to ensure there is a healthy future supply through to sustainable harvesting by carefully thinning woodlands.  This means that all of our firewood comes from local, sustainably managed woodlands.  It also allows us to ensure we only use our preferred species to give you the best performance from your stove, open fire, chimenea, pizza oven or however else you choose to burn our logs.

Sustainable Management

When thinning woods we select and cut the the weaker trees and those of poorer form or target the dominant species.  This encourages better diversity within the woodlands and also lets more light in which helps the remaining trees to thrive, as well as benefitting ground floura and fauna and in many cases allowing an understory to develop.  These things all lead to more healthy, diverse and resilient woods for the furure.  Once the trees have been cut we extract the timber using our purpose-built low ground pressure machinery to ensure minimal ground damage or damage to the remaining trees.  This timber is stacked ready for uplift to bring it back to our yard.

Log Processing

The timber is brought from the woods to our stacking yard where it is stacked for several months to start drying.  It is then transferred to our modern firewood processors which cut and split the wood and then transfer the logs into bags.  The guys in the processing yard do their best to split the logs into even sizes to fit into most stoves but given the nature of the trees that we use, with bends, twists and knots this can be a tricky process. 

While it is nice to have clean, straight trees to produce neater logs we feel it is important wherever possible to leave the better trees to grow on and hopefully one day reach a size and quality that it can be milled into furniture or beams for buildings.

Drying / Seasoning Stage

Once in bags our logs are then dried.  Our Air Dried Logs are stacked in ventilated sheds for several months to season and let the wind blow through to dry them. 

Unfortunately up in the Pentland Hills where we are we get a lot of rain and not a lot of sunshine, not ideal conditions for drying firewood!  Because of this the natural drying process takes at least a year and often more for different species.  In order to keep up with demand we would need to have huge areas of undercover storage space.  We also find that the wood gets to a certain moisture content and then stops drying, often around 20% moisture.  

In order to help the drying process, remove some of the uncertainties of the great Scottish weather and also be able to offer far drier logs which are easier to light and give off more heat we operate a couple of log drying kilns.  These are heated using wood, often blown timber or thinnings from the farm.  The hot air is blown through the logs to wick away moisture, giving far quicker drying times and producing a much drier and more consistent product with moisture contents often in the low teens.  Having been through the kilns the firewood is then stored in a ventilated shed ready for delivery.

We then deliver the logs directly to your address using one of our delivery trucks, in most cases dropping the bag exactly where it is required with no mess.  While the logs go through a screening process prior to going in the bags to remove smaller pieces and debris because they are dried in their bags and not re-screened before delivery you often find smaller pieces and bark that has separated while drying.  Most of our customers have reported that they find it very useful having these smaller bits as they are great for lighting the fire and getting a quick heat, a bit of free kindling filling the gaps between the logs...
