- What does S4S mean?
Try out a caramelized wood like Roasted Ash!
The torrefaction process gives the wood a uniform chocolate brown colour and the grain is quite coarse and strikes a strong resemblance to oak. Usually fairly straight-grained, you occasionally will find curly or figured boards. Roasted White Ash works really well with both hand and power tools and it takes both glue and finish well. We don’t always have it available, so grab some when you can!
If you would like to do the milling yourself - try our 4/4 Rough Cut Roasted Ash Lumber for a more budget friendly version.

We will carefully handpick a high quality board for you. We pay close attention to the wood species characteristics so we can send you a board that well represents each wood type.

S4S Lumber
Who are they for? These are ideal for those who aren’t equipped with the necessary tools to flatten and straighten boards.
The term "surfaced" or "dressed" refers to a piece of wood that has been milled. To achieve the necessary dimensions, we select a larger board to work from. Both faces and edges are then surfaced so you can be assured that the board is flat and straight. These boards are available in specific sizes.
For example: 3/4” x 5-1/4” x 24”
Rough Cut Lumber
Who are they for? These are ideal for those who enjoy working with machinery or hand tools to mill their own boards.
We use this term to describe boards that require additional milling. Rough cut lumber have been run through the planer to show the grain however they have not been dressed. You will need to mill both faces and edges. Rough cut lumber are available in specific lengths with varying widths.
For example: 4/4 x (5-6”) x 24”
You will receive a board that is just shy of an inch thick, with a width in the range of 5-6”, and is 24” long.

I ordered a piece of roasted (caramelized) ash - it is beautiful. Nice straight grain along the length, very straight, no cupping. Very, very happy!
The wood arrived damage free and as beautiful as nature intended. It was quickly put to use and looks amazing.

Ordered the 4/4 Rough Cut Roasted Ash Lumber Pack and couldn't be happier. The grain is beautiful and once oiled it turns super dark. Glad I took a chance on it.
Product was a beautiful colour, and as with all products I have bought from KJP was in great shape
Always professional and helpful. A great local business.
Exceeded expectations
Great material for a custom picture frame
The staff were great help selecting my piece as I was unable to be there in person. Very very pleased as usual.
im very impressed with how this wood looks, and Im looking forward to using it
This roasted ash is really beautiful and has a campfire smell to it. However I found it difficult to work with except with power tools. In chopping out mortises and cutting tenons I got a lot of large chunks breaking off, and in one case split my whole piece apart chopping a 1/4” wide mortise. It was my first time working with roasted wood so perhaps should have chosen a less technical project.
Wood quality was better than expected, received items very quickly, packaging was great.
Exactly what I was looking for. Fast service A++
Very good quality and services. Will order again for sure.
