IMPREGNATION: Lumber,plywood or timber is loaded into a treatment cylinder. The door is  sealed and a vacuum is applied. During this stage, most of the moisture  and the air is removed from the wood cells. The vacum in the cylinder  causes the cylinder to fill with Flame Safe's proprietary Fire Retardant.  Pressure is raised in the cylinder forcing the fire retardant solution into  the wood. The pressure and times varies depending on the species of the wood, the commodity being treated, the cross sectional area,and the  amount of the Fire Retardant solution to be impregnated into the wood.  The pressure in the cylinder forces the remaining fire retardant solution  to flow back into a holding tank. Another vacuum is applied, removing the  excess fire retardant solution from the wood. The lumber, plywood or  timber is loaded onto a tram that services a gas fired forced air kiln.

KILN DRYING: Heated air is used to extract moisture from the wood. A gas fired forced air convection system removes most of the moisture from the  wood after treatment. The moisture laden air is dehumidified. The drying rate is  monitored to prevent cracking in the lumber. Lumber is kiln dried to a moisture  content not to exceed 19%. Plywood is kiln dried to a moisture content not to  exceed 15%. Finished moldings and trim is kiln dried to a maximum moisture  content of 6 to 12 % depending on the species and specific use. Pitch in the wood  is crystallized permitting interior and exterior finishes to be easilly applied. When  kiln dried,Flame Safe fire retardant treated wood becomes lighter and stronger,  maximizing it's structural uses.
