Sodium Silicate, otherwise known as waterglass, is a versatile, inorganic chemical made by combining various ratios of sand and sodium carbonate at high temperature.

The TimberSIL Sodium Silicate Formula protects wood in a radically new way. The new EPA Approved barrier product promises to be gentle to the environment.

“Sodium silicate is a fairly harmless chemical that has been widely used in laundry detergent and other consumer products for over 100 years and as a corrosion
inhibitor in municipal water treatment plants. It is not considered harmful to humans and is not regulated by the EPA,”
-Alex Wilson, executive editor of Environmental Building News

TimberSIL's Sodium Silicate Technology (SST) is a revolutionary process. It binds sodium silicate with the wood fibers, essentially surrounding them in glass (called "amorphous glass") creating a permanent bond with the wood fibers at the molecular level.
