Embossed faux brick exterior panels

Could use some help tagging these exterior panels covering the foundation in a 1940s house in NY.
Panels are screwed into plywood sheathing. No granules… Hard board? Masonite?


Thanks, the closest thing I can find online is Insulbrick…

I never attempt to assign a ‘Brand Name’ to anything. I call it what it is, and describe the condition and concern… “The exterior faux brick siding panels… blah, blah, blah…”

It’s definitely NOT Insulbrick

Q: not Insulbrick because…

Insulbrick is a fibreboard sheathing coated with tar and added granular material, similar to asphalt shingles. The surface was stamped with a brick or rectangular stone pattern. Insulbrick is a brand name and was used for all types of asphalt siding much like most tissues are called Kleenex.

I remember that product, it was a hardboard material and was made to imitate brick, stucco, etc., and was a similar material to Masonite siding. It could have been manufactured by Masonite or Abitibi or another.
Can’t find it online, but I used to see that in the early '70s.

Marcel beat me too it


Yep, had that stuff on my Fathers 100’ long garage. Lasted forever. I still see some while driving around.

Found today’s version of that panel. So if that is what was on that house, it could of been a recent add on.

If it was, it is an interior product not made of the exterior.

47.75-in x 7.98-ft Embossed Red Brick Hardboard Wall Panel

Moisture Rating Dry conditions only

Available at Lowe’s

Here’s a piece… definitely not asphalt based, no granules, not cement…
It’s a soft layered product, looks like cellulose based.

Closest thing I can come up with is “steam-cooked and pressure-molded wood fibers” (Masonite).

Looks like the crap they make the trim boards for manufactured homes from!

MDF is more dense and not so much layered like his small sample above.

Yup… MDF

How does this sound?
The lower foundation walls were covered in a type of fiberboard sheathing - stamped to look like brick. Possibly made of pressure-molded wood fibers.

I would also mention that some of the corners are broke and moisture may affect and promote delamination in the future. But sounds good to me.

Good enough description of what it is… Now just needs the “It’s Broke” and “Fix-it” narrative. :wink:

Did that… and thanks everyone!
