TL;DR
Fiber-cement siding is cladding made of Portland cement, sand, and cellulose fibers cured into dense planks, panels, and shingles that resist fire, rot, and insects — James Hardie lap board being the dominant example. It holds paint two to three times longer than wood, carries Class A fire ratings, and complies with ASTM C1186.
What it means
Fiber-cement siding is cladding made of Portland cement, sand, and cellulose fibers cured into dense planks, panels, and shingles that resist fire, rot, and insects — James Hardie lap board being the dominant example. It holds paint two to three times longer than wood, carries Class A fire ratings, and complies with ASTM C1186. The trade-offs are weight, silica dust on cutting (requiring scoring shears or dust-collecting saws), and strict clearance and flashing details that, when ignored, void the warranty.
