Timbermill log siding is made of vinyl. Log vinyl siding provides the look of wood without the maintenance thatreal wood requires.
Timbermill's log vinyl siding is made using chlorinated polyvinyl chloride, orCPVC, with a backing of polystyrene foam to strengthen the vinyl and provide insulation as well. Chlorinated polyvinyl chloride is a little stronger than regular polyvinyl chloride, orPVC. It withstands a wider range of temperatures without failing.
Available in forest brown or American cedar colors, Timbermill's log vinyl siding doesn't require painting, staining or sealing like real wood. Ownerssimply need to inspect it visually every year and wash it when itis dirty. Timbermill also offers a limited lifetime warranty.
