Re: Vinyl siding over Celotex Absolutely not, vinyl siding will not have any strength to offer the structure on its own. If you really can not afford to do it properly then I would remove any rotted old siding and replace it with plywood and then install house wrap and vinyl siding over that.Feb 2, 2013
It's a wood fiber board with a thin asphalt coating often called "buffalo board" or "beaverboard", the trade name of the long defunct Beaver Board Co. It was an inexpensive exterior wall sheathing.
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.
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
Homasote is a brand name associated with the product generically known as cellulose based fiber wall board, which is similar in composition to papier-mâché, made from recycled paper that is compressed under high temperature and pressure. Homasote contains no adhesives.
Asbestos in Low Density Board (LDB) "Fiberboard" Products. Some low density fiberboard products like those described here were widely manufactured and distributed including in the U.K. and Australia; these products are particulary hazardous if disturbed as they are soft and they contain high levels of asbestos.Dec 15, 2012
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.
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.
Fiberboard structural sheathing is an engineered product made with ground up wood chips and lumber waste glued together with an asphalt binder or resin. The finish of fiberboard is uniform, with no knots or grains like those found in real wood.Mar 25, 2020
Sheathing should be applied vertically with the long edges parallel to the vertical studs. Center all joints over the framing members with a 1/8" gap between edges. Leave a 1/2" gap at the doors and windows. Sheathing should extend from sill to top plate.
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
Fibreboard is an engineered wood wallboard made of wood chips, plant fibres, softwood flakes, sawdust and other recycled materials such as cardboard or paper, all bonded with a synthetic resin under high pressure and heat and then compacted into rigid sheets.May 3, 2013
