Unlike some treated wood, TimberSil does not use copper, heavy metals, or pesticides to resist rot, moisture, and termites. It uses glass.
Non-toxic, non-corrosive TimberSil contains glass particles that have been fused into the cellular structure of the wood. The glass takes up space water would have penetrated, so the wood resists moisture, says Rick Dixon, vice president of business development sales and marketing for Timber Treatment Technologies, the manufacturer. The glass also keeps termites from seeing wood as a food source, gives wood more strength, prevents wood from warping, and makes it more flame retardant.
“The long story short is we’ve taken readily available softwood and made it act like hardwood,” Dixon says. “The only downside is you won’t have a tight-grain look.”
TimberSil can be installed indoors, outdoors, in ground, and above ground. Dixon says popular applications have been shingles, decking, flooring, and exterior flooring.
