摘要： A lightweight wallboard having a density in the range of 10 pcf to 30 pcf and comprised of a faced layer of expanded siliceous inorganic particles, such as expanded perlite, bonded together by inorganic binder, such as sodium silicate. The board is made by depositing a mixture of particles, binder and water onto a moving web of facing material, contacting the mixture with an upper moving web of facing material, compacting the mixture to the desired shape and density and drying the resulting board. Fire resistant and water repellent versions of the formula are also disclosed.

摘要： An economical and uniform fibrous glass mat displaying improved tear strength and a wet forming process of making such a mat is disclosed herein. The mat, which is especially suitable as a carrier material in the manufacture of asphalt shingles or other such roofing products, includes a web of base fibers comprising individual monofilament glass fibers and reinforcement fibers in the form of glass fiber bundles interspersed throughout the web in a randomly oriented pattern. The mat also includes a binder substance to assist in holding the base fibers and reinforcement fiber bundles together.
