<p>The component is impregnated with a liquid preparation containing an agent preventing spreading of flame. An additive reduces the viscosity and/or surface tension of the liquid preparation. The proportion of fire protection agent in the building component on a dry matter basis, is preferably 7-40 wt %. That of the additive is 5-10 wt%. The wood wool fiber length exceeds 8 cm. Its width is up to 6 mm and its thickness is up to 0.5 mm. The wood wool fiber surfaces are largely free of impregnant.</p> |
