Fiberboard requires products or techniques to provide wind bracing and rigidity to the structure. Fiberboard sheathing does not hold screws well; it is also easy to strip the screw holes. Fiberboard sheathing is heavy because it is so dense, which can make it difficult to handle.Mar 25, 2020
Fiberboard products have been widely used on building exteriors as a non-structural wall sheathing, even on some roofs as roof sheathing, and on building interiors as a ceiling or wall covering.
Unless the fiberboard actually absorbed water, can't be dried, and / or is damaged, replacing it is not likely to be cost effective nor necessary. Unless there is a serious mold problem I'd leave the sheathing in place.

For all structural purposes, plywood is much stronger than fiberboard, reveals Bob Vila. Plywood is made from several individual layers glued together perpendicular to each other to provide strength. Fiberboard is made from individual random chunks of wood glued together under pressure without grain patterns.
Fiberboard was not "designed to get wet" as CRS offered in his opinion. Fiberboard or insulating board was traditionally treated with a water resistant surface coating such as wax or asphalt; that product was designed to shed water or to resist moisture.
There's no real benefit to fiberboard other than it's cheap. You'd get more strength with oriented strand board or plywood, both of which are readily available.Jul 10, 2009
Fiberboard cement siding can be hand-nailed, but because it's so much harder and more brittle than wood, you have to predrill holes near any edge.Jul 14, 2021
You can update or otherwise improve fiberboard by painting it. To do this correctly, however, you will need to take a little extra time priming it than you would solid wood furniture because fiberboard is more porous. Other than that, painting fiberboard is similar to painting wood.
Mod. OSB wafer board does not contain asbestos. And OSB wafer board is not a fiberboard product but rather is made of wood chips and glue.
When used with sound-deadening board and gypsum wallboard, outside walls become excellent sound barriers against outdoor noise. Fiberboard sheathing is water repellent, forms a weather-tight cover for walls, and eliminates the need for building paper with most sidings.
Asbestos insulation board (AIB) AIB can be found in numerous locations such as wall panels, ceiling tiles, bath panels, cladding, soffits and much more. This material is high risk and was banned in 1985. AIB is normally a licensed material that should only be removed by a licensed asbestos removal contractor.Apr 17, 2020
