Planning to have spray foam insulation installed in a gut renovation, closed cell Lapolla Foam-Lok 4000. Water supplies are Uponor PEX with EP fittings throughout. There are a few places where there are EP fittings that might end up getting coated with spray foam.
Uponor's installation guide indicates the below.
Spray-foam insulation
Uponor approves the use of spray-foam insulation directly on its PEX pipe and ProPEX LF brass fittings. However, ProPEX EP fittings require an overwrap of 4 to 6 mil poly or other suitable waterproof protection.
Wondering if others have taken these precautionary steps and if someone could provide more guidance on how exactly to install such an overwrap? Wrap poly around the fitting but secure with what? Tape? (thought tape was a no-no on as the adhesive would ultimately damage the pipe.
Any guidance is appreciated!
