We can supply claddings in both Hardwood and Softwood including Redwood, Siberian Larch and Western Red Cedar to various profiles.

Red Pine

All of our sites stock a large selection of machined profiled Scandinavian Redwood for general joinery, all timber having been machined at our sawmill in Grangemouth.

We also stock sawn Scandinavian Redwood in both Unsorted and Fifth quality in recognised imported sizes.


We stock and supply a number of hardwoods for use in construction and joinery.

Hardwoods lend themselves to different end uses due to the various characteristics found in the timber.  As always, we would be happy to provide you with our expert advice to ensure you get the most suitable timber for your needs.
