Intello and acoustic sealant?

Does anyone know if regular acoustic sealant (like PL Acousti-Seal) will work with Intello without damaging it or causing some sort of negative side effects? I'm finishing up my air sealing strategy which will include some Contega HF in the usual places, but I have a larger area to handle with acoustic sealant (for cost reasons) which will be in contact with the Intello.

I just want to be sure it won't hurt my premium vapor retarder.

How to fix a SIP roof?

We recently have had renovations done on our home. We have a structured insulated panel (SIP) home and the roof has always seem to be the issue. The roof originally had the roofing panels directly attached to the SIPs. We change it to have furring strips and than more plywood and than roofing materials (wrap and shingles) to allow air flow. This however has created more sweating to the inside of the house. We have moisture coming down through the ease of the roof in several rooms. Does anyone know how this can be fixed or what we should do to correct this problem?

Anyone use Dennyfoil to block fumes from a renovation?

A Contractor is renovating two walls in my apartment near the windows. I’m very chemically sensitive. one suggestion is to place dennyfoil on the wall to block the fumes from coming into my apartment.

Has anyone used it successfully for this purpose and have any suggestions
On how to reduce the risk of mold growing. One person suggested applying the foil tightly to the wall using tape. To not use the air conditioning. And to consider getting a dehumidifier when it’s humid in my apartment.

She also recommended I consult with a building science expert. Any advice or feedback?
