Asbestos content of Esclad building sheathing products.

This article addresses worries about asbestos in insulating building roof or wall sheathing - a question that comes up during building demolition and renovation.

This article series provides fiberboard product names and we describe the components, properties, and applications of various fiberboard, hardboard, and insulating board or sound deadening board products.

Esclad Sheathing Board Properties

On 2021-04-09 by (mod) - does Esclad™ Sheathing Contain Asbestos? No.

@scaredofasbestso, a bit of research suggests that the sheathing in your photo is a polystyrene foam board used as exterior insulating cladding on buildings.

Fiberboard sheathing products are also within the products made under the Esclad name.

If you can give me a sharper, closer photo we can say more about this speciic Esclad sheathing product.

Esclad™ is a Canadian product line named in 1988 in a U.S. patent. The the current owner is

• St-Michel, Andre. EXTERIOR INSULATING SHEATHING [PDF] U.S. Patent 4,786,547, issued November 22, 1988. Assigned to DOMTAR Inc.
  
  Abstract: An exterior insulating sheathing which comprises a foam polystyrene ply and a second ply glued to said polystyrene ply throughout. The second ply is preferably a fiberboard but may also be a waferboard. The sheathing is nailable, has a racking load of about 1900 to 3700 lbs, and has at least he exposed side of the second ply water resistant.
  
  This sheathing has a minimum tensile strength of 65±14 kPa, a linear expansion at 97% RH and 23° C., of less than 0.40%±0.02, a water vapor transmission of at least 96ng.Pa.s.m2, and a modulus of rupture of 0.5 to 17.2 megaPascal.
  
  Excerpt: Broadly stated, the invention is directed to an exterior insulating sheathing comprising a foam polystyrene ply and a second ply which is preferably a fiberboard ply or may also be a wafer -board, said second ply being glued to said polystyrene ply throughout with a continuous layer of glue,
  
  so that said continuous layer of glue is sandwiched between said foam polystyrene ply and said second ply has to continuously fasten said polystyrene ply to said second ply, to form a unitary product defining a sheathing,
  
  said sheathing having the exposed side of said second ply board water resistant, said sheathing being nailable and having a racking minimum load according to the ASTM E-72 of 1900 to 3700 lbs, a minimum tensile strength of 65±14 kPa, a linear expansion at 97% relative humidity (RH) and 23° C., of less than 0.40%±0.02, and a minimum water vapour transmission of 96 at least nonagram per second per meter square (ng /Pa.s.m2 ) and a modulus of rupture of 0.5 to 17.2 megaPascal (mPa).

Can you tell us, for the building in your photo:
