This product has a unique look and design. It is a shiplap product with an exposed tongue where an application of a brush on chinking will simulate a standard chink line for substantial saving in cost. We rough saw this to a 1 ¼” thick, kiln dry it then put the pattern on it. Take a look at the photos and installation section to get a better feel for this product. We have worked with the lab at Sashco to formulate a mixture of their standard Log Jam chinking that allows us to brush the chinking to the tongue of this product. We often stain and chink this product before shipment allowing the customer the ability to immediately install the finished product.
