Manufactured from select, seasoned hardwoods. Flammability level not less than 30 minutes. Superb work ability, easy to assemble and transport. Available in large panels which reduces costs and saves time of using joints.
To make the plywood resistant to fire, the sheets are treated with Fire Retardant chemicals under Vacuum Pressure Impregnation. This ensures its resistances to immediate ignition and flame penetration. All these attributes make DURO FIRESHIELD the perfect choice for your interiors.
The DURO FIRESHIELD surface is coated with special chemicals but easy care is what's necessary in handling, storage and fixing to ensure satisfactory performance.
Plywood being an organic material cannot be made completely fire proof. However, with the absorption of specified quantities of Fire Retardant chemicals under Vacuum Pressure Impregnation, resistance of DURO FIRESHIELD plywood has been considerably improved to ignition, surface spread of flame penetration.
