The cover board is adhered using hot asphalt or a specially formulated adhesive that is applied over the top surface of the bottom layer of insulation. Second, the cover board serves to insulate the fastener eliminating energy loss and possible thermal bridging at fasteners and insulation joints.Mar 2, 2004
Bitumen Impregnated Boards. EXPANSION JOINT FILLER. DESCRIPTION. A preformed expansion joint filler board for joint in all concrete structures and brick structures. It is manufactured from high grade slow growing scandinavian wood fibers which are bitumen impregnated and compounded into a compressible non extruding ...
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. Like.
Elastomeric roofing membranes, modified bitumen membranes, or built-up roofing may be heat-welded or hot-mopped directly to STURDY-DEK. The asphalt board then becomes an integral part of the roof membrane, making it stronger and more puncture-resistant. Dimensionally stable, water-resistant, tough, durable panels.
This is just recycled paper / cardboard with an asphalt coating. It still soaks up water like a sponge so you have to paint with an expensive exterior paint, even then it is a waste of good paint.Mar 1, 2022
Bitumen Impregnated Fibreboard is an expansion joint filler supplied in sheet form and is used to form and fill expansion joints in in-situ and pre-cast concrete construction.
Beaverboard®, black board, buffalo board, gray board, cane board, Celotex®, Homasote®, Insulite®, Nu-Wood® are some of the many names of fiberboard or plant-fiber board sheathing products used on roofs, exterior walls, interior walls & ceilings.
The Zip System R-Sheathing is a compelling product because it saves several steps by installing all the necessary wall components in one go. HOWEVER, from the pictures on their website, it looks like the Zip System R-Sheathing has the WRB on the outside, followed by the sheathing, followed by the insulation.Feb 16, 2017
OSB (½-inch) has an R-value of 0.5 – 0.62.Mar 25, 2020
Burning of asphalt impregnated and/or coated wood can produce irritating and potentially toxic fumes and gases, black smoke, carbon dioxide, carbon monoxide, sulfur oxides and hydrogen sulfide.Jan 12, 2009
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.
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.
R-1.3The best practice for increasing the R-value in exterior walls is to protect them with insulated foam sheathing. Some builders use 1/2-inch wood sheathing (R-0.6) or asphalt impregnated sheathing, usually called blackboard (R-1.3) to sheath the walls.

The material is noncombustible for high fire resistance and is water-resistant. Dens-Deck provides an excellent substrate for all types of conventional low-slope roofing membranes, particularly in fully adhered assemblies. The material is durable and provides superior impact and puncture resistance.Mar 2, 2004

Product Overview This cost-efficient product features interknit wood fibers that protect against on-the-job abuse and help supplement required wall bracing in traditional stud wall construction. It also helps stop water intrusion and slow air infiltration. Produced from residues of southern pine sawmills.Mar 12, 2020
Fiberboard sheathing permits water vapor generated inside the structure to pass through the wall cavity, thus reducing the potential of trapped water within the wall. Fiberboard sheathing is consistent throughout, so cut edges are smooth, without voids or splinters, and can create decorative edges.Mar 25, 2020
Semi-rigid board is composed of a mineral fortified asphaltic core formed between two saturated fiberglass felts. This board is designed to be used as a substrate material in low-slope roofing. It can be installed over wood, rigid insulation or as a recovery board over an existing roof surface to be re-roofed.
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.
Fiberboard does not contain asbestos. Asbestos was banned in 1977 and cannot be used for any construction materials.
Decking Delivery's Plywood Buffalo Board is strong, durable and easy to work with. Perfect for indoor or outdoor use with a quality smooth finish.
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
