Resumen:
The aim of this paper was to know the fire performance of wooden panels (Araucaria angustifolia) impregnated with soluble alkaline silicates (water glasses). Commercial silicates based on sodium and potassium with 2.5/1.0 and 3.0/1.0 silica/alkali molar ratio were selected; solutions and glasses were previously characterized.
Experimental panels were tested in a Limiting Oxygen Chamber (LOI values) and in a Two-Foot Tunnel (Flame-spread index, Panel consumption, After-flaming time and After-glow time). Testing results displayed a high fire retardant efficiency and a minimum thermal expansion of some soluble silicates.
