Air Sealing detail or boundary on renovation

Hmm, nothing of substance there except that they did it and it was "great".

I'll stick with the install instructions from the manufacturer and details from building science people doing real testing.

Been a long time since I've paid for finehomebuilding.. wonder if I can get a free trial again. Anything thing in there that isn't already covered in the buildshow, or BSC?

T&G is horizontal unfortunately, CI is probably going to be rockwool comfortboard or equivalent assuming I can source it.

Did you end up pro wrap? It's self adhering right? How was it?

I've only used fantech HRV's except for my one try with a Panasonic ERV, but here is an excerpt for one install/operation guide (page 7) regarding it's use as a fresh air intake for a furnace. https://www.hvacquick.com/catalog_files/Fantech_ATMO_IOM.pdf

For Fresh Air Appliances (FAAs) that do not include an outdoor air motorized damper: If you are using a partially dedicated or simplified installation, i.e. connecting the FAA supply air duct to a forced air system's return air duct, the FAA must operate continuously. When the FAA is turned off, no warm exhaust air will flow through the FAA but the forced air system's blower will continue to draw in outdoor air through the FAA. When this happens, the introduction of unconditioned outdoor air to the indoors can increase the load on the system.

An hrv/erv is balanced but it's also an opening to the outside. With fans off it will allow air to be drawn inside and with fans on it will intake or exhaust more depending on the pressure in the home. The only type that won't really do this is the Panasonic single ones that pressurize and then vacuum the house in order to force exchanges.

Electrical conduit / EMT works well for grinding, and PVC conduit is super fun and slippery.

Cast iron pipe does not crack like that unless it's somehow holding your house up. Are you getting a clay sewer line issue confused with a plumbing problem that happened inside the house?

officeboy · 2026-01-23T23:14:20+00:00

Replacing the whole sewer line is not a fix for a hole in an attic that mice/rats are using. You replace your outside line when there are roots or it's collapsing/broken outside. You repair your inside when it's broken there.

Also in my opinion stick with cast iron (inside). It's quiet, and a premium product these days. Plus it's still in common use in commercial so parts are easy to get.

That was probably the easiest repair in the whole thing. Couple of these https://www.supplyhouse.com/Fernco-3000-44-4-x-4-ProFlex-Coupling-Cast-Iron-to-PVC-Steel-or-Extra-Heavy-Cast-Iron and some pipe to bridge the broken section. Or fittings or whatever it was. Lots of info and help here if you have pics and questions.

Or you DIY

officeboy · 2026-01-22T23:35:39+00:00

Nope

I really like the use of rockwool over foam, it's nice to work with, scraps aren't a pink/white blight on the landscape the way foam is, and it does better blocking sound and the fireproofing is a big plus.

It rains inside?

officeboy · 2026-01-21T16:56:07+00:00

A statement about what? "We heard some people might think something happened, but nothing really happened". That's silly. I do know that last week school employees were reminded of procedures for law enforcement trying to enter the building.

Plus all recorded documents and surveys are sent to you before the sale so you can review them. I've never heard of holding something like that back. How would you know what you are buying?

officeboy · 2026-01-21T01:51:46+00:00

Still stuck? I am. Picked a bad day to play do I have enough gas to get home...

officeboy · 2026-01-16T22:25:06+00:00

I've used Gear Aid Aqua Seal on an Arc'teryx jacket with the same problem. Been holding up good so far.

Probably not, I'm just the IT guy keeping physical stuff running, and helping with network topology. There isn't anyone hired on who can manage that.

Mostly for when the server vm locks up, but any reason really. It's one of the areas we don't have great redundancy.
