Curious what guys have done to hang lineset without crushing the foam insulation?

I'm considering grey PVC conduit, cut into 6" or even 12" sections that should side easily over the insulation and then 1" band iron around that to rafters.

Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment

    Something like this is one of the methods we use. Not quite as big, however, & more often use teardrop hangers, but pretty similar. You should be able to source them from an insulation place.

    This is similar to what I have been considering making out of 3" 26 gauge round duct.

    That would work too I guess. We use the manufactured ones. It's sometimes hard to coordinate all the sizes (Armaflex OD, saddle, hanger, sleeve, etc.), but it looks good when it's done. I'll put a touch of Armaflex glue on the saddle to keep it in place of necessary. Two hole strappies will work also if you're running parallel against the framing.

    I like your PVC pipe idea. You can buy two hole straps for whatever pipe size you choose will look better than the band iron or use minerlac electrical clamps that can be attached with wood screws

    The minerlac come with 1/4" holes but I have drilled them out to 3/8" so you can use 3/8threaded rod with base plates or whatever.to attach to the structure

    use 3/8 nut with 9/16 hex they fit in the minerlac better than the 11/16 hex

    If you use PVC or metal sleeves Sioux Chief has some handy hangers.

    I use them in my shop to hang cords and air hoses.

    1¼? Those will compress the insulation around the suction line, resulting in a LOSS OF CAPACITY. No way ChrisJ would do that. ;););)

    That's my biggest concern.

    First rule of insulation in my house. We don't compress the insulation. :p


    One thing I'm unsure of is if 2.5" PVC is big enough for my 3/4" thick 7/8 insulation. If I did my math right, it's 0.75 x 3 = 2.25". That may be a big tight to slide 2.4 or 2.5" sleeves over especially if the pipe isn't perfectly straight.


    But I'm not a perfectionist.

    And, I didn't do my math right.
    7/8" line is 3/4" ID.

    2.4" OD.
    That'd be pretty tight..............

    3" PVC is a common size, I'm not sure if 3" SDR 35 is available but thin walled PVC duct pipe is. If cost is the concern.

    3" aluminum vent pipe is another readily available inexpensive saddle material.

    My local insulation supplier has a small metal roller and he makes his own saddles from flashing aluminum roll material.

    TG you fixed the grievous math error. I wasn't going to let the 1/8" slide.
