Prefab Hose troth

[Roz]

starting a rehab project where the self service bay lines are just lying in the attic unprotected. I can only imagine how they faired in the winter months. Has anyone come across a prefab insulated troth for the bay hoses? Otherwise I will find a carpenter to build us the insulated box. Thx

A lot of washes here have a galvanized steel trough that runs the length of the car wash. I'm pretty sure they're just cut and bent to order.

We’ve gone to a sheet metal furnace duct fabricator and had them make up hose troughs. We then line them with ridged foam board. Once installed we laid self-regulating heat inside to keep everything warm.

I also have galvanized ducting running above my bays. I line the bottom with a rigid foam the hoses lay on top of that and the floor heat line runs through it as well. The top is open but I sandwich another rigid foam insulation on top of the hoses. Works great

Like the approach. Thx

We make galvanized ones in 10ft sections with 1" rigid insulation. Not sure of the cost right now because of the state of metal prices but probably at about $200 a section. What can also be an issue is shipping. Shipping anything outside of a standard 4' x 4' skid can get spendy

Cool. Can you let me know how to order, and perhaps post a pic? I am going to check locally (Maryland) to see if a HVAC place might have something but will get back to you if nothing found. Thx!

PM me your billing/shipping information and I'll figure it out.

My apologies, I was not aware but we have discontinued the prefabbed troughs. There just wasn't enough interest.

I just use a 6 inch PVC pipe and then run it into a large electrical box ofr each bay. We use heated roof cable in the pipe and it has kept us working for 25 years but we only get down to - 30 F so it may not work in all situations.

This is what my guys just fabricated in our shop for my current rehabbed project. Something like this should work for you.

I got my measurements and called a couple local sheet metal shops. They bent the panels for me and made end caps as well. The price was very reasonable. Given lumber costs today plus the labor to build a trough I'd say you'd come out cheaper if you went with sheet metal and have the added benefit of it lasting longer. Just my 2 cents.

We use a local “residential duct supplier” to fab our troughs.

22ga galvanized steel, bent to form an “L”.

8-1/2” wide x 5-1/2” high x 1” lip x 10’ long.

2 ”L“s create the trough and provides swing room for wrenches.


We glue 3/4” polyiso to insulate…and heat cable to keep it warm.
The Dewalt track saw makes quick work of cutting the polyiso.

I used 12" pvc pipe cut in half.
For insulation, I laid reflectix in the pipe, simply fold it over once the hoses are in it.
A big part of my reasoning was that I really really like easy access for maintenance

edit: OurTown, good point. For the record, mine is in the attic. Yes I have heat tape in it too.

Just keep in mind that the original post was for a trough in the attic and not on top of a flat roof.
