AT TimberSIL we surround the millions of fibers that comprise wood with layers of amorphous glass that are only a few molecules thick.

TimberSIL® wood has gone through a sodium-silicate-based process for treating wood that relies on a micro-manufacturing technology to create an effective barrier to rot, decay and common wood problems. The patented process uses heat to change a proprietary formula from a soluble solution that is infused into the wood and turn it into a microscopic layer of amorphous glass throughout the wood, providing an effective, permanent barrier. The wood is non-toxic, odorless and nonvolatile, is not corrosive to fasteners, does not cause excessive wear on tools, and has a natural clear color. TimberSIL® Decking and other exterior products carry a 40-year warranty.

TimberSil Glass Wood is more stable, safer, stronger and longer lasting than natural or composite wood / lumber. TimberSil Glass Wood is an effective fire retardant, barrier against insects and is guaranteed not to rot or decay for 40 years. TimberSil Glass Wood, to the naked eye, looks like natural wood and retains all the benefits of natural wood.

TimberSil infuses a water-based formula containing various ingredients, including sodium silicate, into the wood and then heating it under certain conditions. The result is the millions of fibers of which wood is comprised are surrounded with layers of razor-thin, amorphous glass
