Re: Insulating Sidewalls of an Old House


I'm so sorry to have thrown off topic the thread, but I can't help myself. Forgive me form8892.


Fair warning, folks in construction up here tend to be "old dogs," really stubborn about changing "how they been doin' it fer their whole damned life" - I literally spent 45 minutes on the phone watching YouTube videos with a guy regarding 24" OC studs in the new addition I'm planning - he was quite sure I was full of **** LOL (I was actually wrong, the engineer guy we ended up talkin to later said 16OC was better with the quakes, even if the insulation properties of 24OC were better.)

That said, the standard technique up here is to staple the VB and Tyvec to the studs. Every little staple hole is going to let air and moisture through though, maybe /IF/ you're using a machine that exactly centers the staples on the 2by, but no one is doing that around here so there's always some penetrations.

Do ya'll tape over the staples to prevent those tiny penetrations then? We'll tape the seams of the different sheets - and we try to go horizontal rather than vertical, so there's typically one horizontal seam (two if you've got a higher ceiling,) but nothing over each (or well any, like I suppose it's around every three) stud staple line.

Balloon framed houses were built with studs that went from the foundation to the attic, they are a fire hazard as any fire that gets in a wall gets to the attic in seconds, but besides that much cold air can be dragged up from the basement or crawl space and that can account for many of the drafts.

Any time you open a wall and find that you should block them with a 30 min. fire rated product. It would be worth checking crawlspace and attic.

" Every little staple hole is going to let air and moisture through"
And that is one of the differences between an air barrier and a vapor barrier. An air barrier needs to be sealed where a few holes in a vapor barrier only allows an equal percentage of moisture through. I probably stated that poorly but basically a VB with 10% of the material missing is still 90% effective.

No citation at hand.

Re: Insulating Sidewalls of an Old House


That much tree cover also doesn't help with drying. Also why insulation? Cold or want to save on heating cost? Also don't see any roof venting. Any insulation starts with sealing the air leaks. Most air leaks are through the wall and windows. These are also hardest to seal and costly, although if willing and able to remove plaster and lathe and drywall later, air sealing and insulation in old walls pays off big. There is no easy answer. If residing is possible, you can cover the outside with foam boards, paying absolute close attention to every joint and gap. From inside you could start with plaster gaps around electrical boxes and outlet covers. Removing base molding, you can seal under the plaster and floor. You can also seal some of the foundation to plate gaps from inside or outside (if outside, don't seal if you can't see this gap).

Blow in cellulose was popular but I'm against it these days. Blow in walls, after the fact, is blind install and cellulose can hold water way too long. Also not much roof overhang and that much gutter clogging trees ups the chances of leaks into the walls.
Good insulation needs to have good inspection and good practices go into it. Willy nilly stuffing or blowing in is waste of money and material and can cause trapped moisture.



Sorry but a second look at the photo shows no gutter? That means lots of water around the foundation and the house as well.

Re: Insulating Sidewalls of an Old House


We don't know what your wants or needs are.

You have to do a list of all the things you want and all the things the house looks like it needs



For now we can see a paint job. rot repair, maybe new roof and gutter on the back, a little re work on the roof structure to make gutter work.
Insulation,, roof ventilation?? re landscape around the house to expose foundation.



What refinish does it need inside, condition of plumbing and HVAC, wall and cupboard and electrical. Whats happening in the crawlspace.


Once you have the list then you have to work out what the priorities are and what order things should be done so nothing has to be ripped apart twice.



Usually you try to get it water tight before you do much on the inside.



Do you expect to live in the house while work is being done, will you be doing most of the work?

Re: Insulating Sidewalls of an Old House


I am planning to live in the house. I know the house needs lots of work, but due to lack of money and time I am planning to level the floor on one of the rooms, bath and kitchen. will re-do the whole bath.

Also trying to put insulation (curren thread in question) on the walls, install an HVAC unit as it does not have one.

Please advice on changing the electrical wires and any other suggestions, please feel free to do so. All the work will be done by a third party company as I do not have the expertise neither the time to do it.

Thanks.

Get as much info about the electrical as you can and start a thread in electrical about that.

Size of main breaker, maybe with pictures, type of wire, with ground or not, do the wires run thru the attic with porcelain insulators.
Will you level the floor from below or above?

You have some open space around the side or back, there could be rot that should be checked, often the repair around the perimeter also fixes floor levels, if you level the floor from above the other fixes become more difficult. That is what I was talking about when I said list all the problems and look at all in some detail so you get them in the right order. Floors that sag in the middle may best be fixed from above but if they slope to one side that is often best fixed from below.

Re: Insulating Sidewalls of an Old House


So you are saying the rot on the back left side of the house should be fixed first before starting to level the floors? This should help level up the floors in the house?

I do forgot to mention that's one of the things that was on the list to fix.

If you have room enough in the crawlspace I would set up a laser level and go around and measure up to the sub floor all around the perimeter and bearing walls in the center. That would tell you where any problem areas are and if they are the cause of the floor in question.
I would map and record all the readings. You can also poke at the wood with an awl or ice pick or even a sharp screwdriver and soft would might indicate rot. Then when you are down there you also have a look for what material is used for water and sewer pipes and their general condition.
