Steven Hockstein Posted June 15, 2015 Report Posted June 15, 2015 This is the first time I have ever seen this material. It is about four inches thick and solid (almost feels like a lightweight slab). The photo was taken at the entry hatch to the attic. The house was built in 1950. It is a slab on grade ranch house. I told my client that I have not seen it before and I will try to do some research. Now I am asking my home inspector think tank. Opinions? Click to Enlarge 58.66 KB
Jim Baird Posted June 15, 2015 Report Posted June 15, 2015 ...I have seen something like that only in an institutional setting, and it was used then for sound dampening.
Jim Katen Posted June 15, 2015 Report Posted June 15, 2015 ...I have seen something like that only in an institutional setting, and it was used then for sound dampening. Same here. I believe that someone posted a picture of this stuff before and Mark Cramer identified it, but I don't remember what it was called.

Steven Hockstein Posted June 15, 2015 Author Report Posted June 15, 2015 Looks just like Durisol form boards It looks like the form board material but it is white. The boards seem to be part of the original construction. Was this product in use in 1950?
Steven Hockstein Posted June 15, 2015 Author Report Posted June 15, 2015 Homasote? Fibers seem too large to be Homasote.
AHI in AR Posted June 15, 2015 Report Posted June 15, 2015 Looks like Tectum to me. I've seen it used on exposed commercial vaulted ceilings. Roof deck and insulation in one panel.
mjr6550 Posted June 16, 2015 Report Posted June 16, 2015 Looking at the left part of the photo, I agree with Tectum. The right part does not look quite the same.
Steven Hockstein Posted June 16, 2015 Author Report Posted June 16, 2015 OK, I am glad it is not just me. This one has me stumped. The material is installed throughout the attic and directly above the flat ceilings. It does not feel like a foam product. It is what I would imagine what an OSB structural panel would feel like before it was compressed. I also don't know if it contains asbestos since it was installed over 60 years ago.
Marc Posted June 16, 2015 Report Posted June 16, 2015 I've seen something that looks exactly like it that was installed as suspended ceiling tiles on old school buildings. Was this insulation panelized? Marc

Was this insulation panelized? Marc They are some type of rigid panels. There is a finished ceiling installed under them. Access to the attic has been blocked and there is only a small opening that I could barely fit my head through to see. I took a few photos and this material is over all visible flat areas. I am also concerned that there may be asbestos fibers in the material.
Rob Amaral Posted June 16, 2015 Report Posted June 16, 2015 Almost looks like some sort of eel-grass product???
