1/2\" Fiberglass Insulation -- Adequate?

Foreman

I used, inch and a half (1.5") on my mains and never feel any residual heat being lost thru it. Glad I went the extra step.

They were out of 1\" insulation . . .

. . . at the pipe store for 1.5" pipe. I got 1" for all the other pipe, about 3/5 of the approximately 50' of main (two branches, 20' and 30'). So about 2/5 of the main is 1.5" pipe.

The guy at the store said 1/2" fiberglass insulation would be adequate for my needs. I bought the stuff, but before installing it I want to get confirmation that it will really do the trick. Otherwise, I'll retutn it and wait until the 1" is in stock again (or try to hunt it down elsewhere).

Thanks.

Get the 1-inch if you can. Do it right.

1 inch insulation

Eric:

What you can do is put the 1/2" insulation on the pipe and then cover that insulation with another layer of insulation. You can put a string around the outside of the insulated pipe and bring it to your supply house. They can tell you the bigger size - they will probably have it with the 1 inch wall. This way you get 1 1/2" total and are not wasting your initial purchase.

Also, make sure your main vents are properly vented. Call Ken Kunz at Gorton (908) 276-1323, and he can help with venting.

Plan A . . .

. . . is to return the 1/2" and get 1". The 1" I've installed on the rest of the main is doing a great job.

I actually talked to Ken Kunz a couple of weeks ago. He suggested #1's on the dry returns; Steamhead recommended a #2 on my long main and a #1 on the short one.

This past weekend, I installed all this stuff (as well as piping in two drips, which the main most astonishingly was lacking).

Hi, Eric

Hope to return your call today. Of particular interest for all here interested in energy conservation, The International Energy Code requires a MINIMUM of 1.5 insulation on pipes 1 1/2 inches and smaller and a minimum of 3 inches on pipes over 1 1/2 inches for steam use. For hot water the numbers are 1 inch and 1 1/2 inch, respectively.

Gets you thinking, eh. We use 12 inches in our attics, when the dleta tee is only 70F, but only use 1 inch on our pipes when the delta tee is 140F.


Hummmmm
