Best product to "seal" access panel in hvac duct?


What would be a good weatherstrip type of product to seal up an access panel in a square duct? This panel would be opened and closed here and there so it cannot be permanent. Something that will keep air and temps within the duct. Thanks for any help. -Mike

If you have an actual hvac access panel (they are made in 6" x 6", 8" x 8" and 10" x 10" and I think 12" x 12") than the only sealing you need to do is around the rim. You can use foil tape or hardcast mastick. Between the removeable door and the rim that is cut into the duct and will remain there is already a seal and in the door itself is insulation.

I will most likely be making the door myself since I need it to open inwards. What is that above ^^^^?

That is an access panel specific for hvac, the door removes completely.

Why do you need the door to open inwards?

Well, I either need it to come off completely or open inwards. Do you have links on where to buy those? Thanks!

That looks to be hinged which would only open outwards. You can try Lowes as well as calling your local hvac supply houses or Grainger.

Thanks. No links to the original two pics?

My main goal is to create a bypass where I can block off airflow to my first floor and redirect it to the basement. I thought the best way to do that would be a door that when open stands up straight and cuts off airflow so it all comes out the opening that remained when it was lifted. Not sure if that will be possible unless I make my own.

Okay, now we're getting somewhere. Redirecting air would be adding a duct line (to your basement) and using dampers to balance the air internally. What a damper is is a door that sits directly in the duct, right at the plenum, that you can close or open, cutting off air flow to certain areas while forcing the air (in greater velocity) elsewhere. You can slightly close it off or close it off all the way.

Do you have a duct running to your basement now? Why not simply run a duct straight off of the plenum to the basement? Are you trying to tie into a duct line or the plenum or is this line to the basement already there and you simply need more air through it?

Can you take some pics of your duct work and to where you need more air?

You can google "Duct Access Panel" and find tons of them but here's one. I already posted one link to The Home Depot.

I know about dampers, but they won't work exactly how I need them to since they are more like a throttlebody. I need a diverter. I could use a damper and an access panel in conjunction, but I've had trouble finding rectangular dampers.

This is the main trunk line to my first floor. It runs along the ceiling of my basement and is 12x18. I want to heat and cool my basement using this line. So I need to completely cut off airflow to the basement when not using it so that I can heat and cool the first floor without leaking air into the basement. I also need to able to completely or mostly block off air from going to the first floor while sending air to the basement.

If I just added another line to my basement then the air would still be shooting upstairs. Plus I'm also adding another "door" for the return.

Flex duct or metal? Round or triangle?

Take pics of it all, of everything you plan on doing and existing. It's much easier to help when we can see what you're seeing.
