What is the sheet metal fire block between floors called? There is a plate around the HVAC ducts in the walls.

I want to run some blue flex conduit past it from the attic to the basement. What is the best way to do this? Drill out the sheet metal? I reciently found out that the fire foam is not actually to code which is exactly what I did to seal the cracks. Fortunately I didn't seal up the wall yet.

 

Forgot to add the (mostly) finished pictures

Didn’t post any work in progress photos








Mostly completed pictures.. Wife needs to pick out window shades, night stands and so on.. My work is complete..
Ceiling fan I installed..

 

Wtf is up with those diagonal boards? I havent seen that before and dont really understand what they are actually doing?

 

I believe they are for added stability and strength.

 

New bathroom going in:











Still a work in progress but hopefully should be done soon.

 

Fire blocking would be my guess

 

A little more info and a few photos? Commercial building? Residential? Timber-frame? I’m not aware of sheet metal fire stop between floors in any building I’ve seen.

 

Residential. Built in the 70s. Timber frame

This image isnt mine but it's very similar. I have a rectangular HVAC return going in the basement. The is an area around 1sq foot next to it that is cover by the sheet metal each floor has these plates.. If the sheet metal wasn't there, there would be a clear path from the basement through the 1st floor, 2nd floor, and all the way to the attic.

To reiterate my question, I would like to run blue plastic conduit through that area. How can I do it safely?

 

Gas fireplace?

 

Do you know if the house was built with central AC? I've seen something like that when homes are retrofitted with central AC. The HVAC guys work better with sheetmetal, not plywood, so they just holes back with sheetmetal.

 

that is B-Vent (double wall for flue gas) there needs to be no combustibles touching it so metal stock is used ether flat like shown or there are trim rings that are pre-made for making it look nice when it has to be seen.
it is just referred to as flashing buy most Tin Knockers

 

Is that a coffee cup? Whatever works lol

 

That is the case and you also needed an external disconnect for years already when the panel inside wasn't directly behind the meter outside

 

Installed a water reciculation pump, was taking forever to get hot water to opposite side of the house. Now it should be faster. Easy install

 

I usually install a dedicated hot water return loop with a recirc pump on it on all my houses , plus we fully insulate all the hot water lines with pipe insulation even in interior walls and floors

well worth it

 

Its got a check valve at the furthest end of the house connects it all in a loop. We will see how well it works

 

I finally installed a new outlet behind the tv. No no more wires.




Also added an outlet lower behind my garage fridge
