We are currently working on a building with exterior walls constructed of prefabricated SIPs. Any nessecary wiring is run in a chase cut out with a hot knife and MC cable laid in the cutout, after the cable is installed the insulation is trimmed and reinstalled with metallic tape used to seal the over it. We were instructed by the manufacturers rep. on-site that this was acceptable. Our local AHJ has asked raised a concern about heat buildup in the cable as installed and wants documentation that this installation is acceptable. The only response I can get fron the manufacturer is " that is how we always do it". Has anyone else run into this? If so, how was it finally resolved?

This situation may be one where you need to
"let the Manufacturer and the Building Department Fight It Out"

Try looking through the Company's website for documents which support the claim(s), then present these items to the Inspector or Building Department to see if they accept it or not.

If no documents are available to support the claim(s), or the AHJ (Building Department) does not accept the documents, let the Manufacturer take over, and come up with a method which will conform to your DBS's minimums plus not be a complete loss for you and the Mfr.

Good luck, and let us know what the outcome is.

No George, you're not the only one. But myself, I have always subscribed to the idea that it's better to remain silent and let everyone think you don't know anything than to open your mouth and prove it. [Linked Image]

George Little -

"Am I the only one that does not know what a "SIP" or a "DBS" is? It would be nice if you guys would spell thing out for us dummies."

Nope, I would be one of the other dummies that doesn't know what "SIP" and DBS" means.

"No George, you're not the only one. But myself, I have always subscribed to the idea that it's better to remain silent and let everyone think you don't know anything than to open your mouth and prove it. "

But if I stay quiet, then how will I "know" what "I don't know"?

Besides, how will all the other dummies that don't speak up find out (g).


Thanks
Steve

I believe SIP means "Structural Insulated Panel", and is a pre-sheathed bunk of insulation. Not sure about DBS beyond satellite TV.

Sorry guys! A SIP is a structural insulated panel. These are styrofoam filled metal stud wall panels. They come in prefabricated panels and are stood up on site. The building looks like a big white styrofoam cooler. Siding and sheetrock will be installed as usual. The manufacturer has no info. avalible on-line and so far has not been able to provide any.

I believe what your AHJ is looking for is a sealed letter from the company engineer that this product is safe to use in these walls. As an inspector I required letters myself, Good Luck.
