Problems solved by technology

However, cellulose fiber cement materials do not perform as well as asbestos fiber cement materials in that the cellulose fiber cement materials have lower resistance to water induced damage, higher water permeability, higher water migration ability (also known as wicking) and lower freeze thaw resistance when compared to asbestos cement composite materials.
These drawbacks are largely due to the presence of water conducting channels and voids in the cellulose fibers.

Embodiment Construction

[0030] This description of the exemplary embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description, relative terms such as “lower,”“upper,”“horizontal,”“vertical,”, “above,”“below,”“up,”“down,”“top” and “bottom” as well as derivative thereof (e.g., “horizontally,”“downwardly,”“upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both removable or rigid attachments or relationships, unless expressly described o...

Abstract

A product comprises a fiber cement substrate, and a porous, closed cell foam joined to a substantial portion of a major surface of the fiber cement substrate.

Description

FIELD OF THE INVENTION [0001] The present invention relates to building materials generally, and more specifically to fiber cement exterior building materials. BACKGROUND [0002] For more than 100 years, asbestos fiber cement materials were prevalent in such building products as roofing. In the 1980's, as the dangers of asbestos became known, replacement building materials were sought. [0003] One proposed replacement for asbestos has been unbleached cellulose fibers, with about 35% cement, and about 55% fine ground silica, such as described in U.S. Pat. No. 6,030,447, the entirety of which is hereby incorporated by reference. This product is autoclave (steam heat and pressure) cured. It is generally made on a Hatschek machine. Cellulose fiber cement building products have surged in popularity in recent years. A variety of products are available in fiber-cement, including siding, shakes, and panels. Fiber cement products are strong and durable. Advantages of fiber cement products incl...
