Let in bracing isn't done much around here anymore. Lots of plywood corners and blackboard.

I worked on a house built in the 50's that had diagonal 1x12's for sheathing.

If you tape wire nuts, the box is purely optional. If you put enough twists in the ground, the green wire nut is also optional, I've heard it called "western-union"

One of my friends puts tape on wire nuts for some reason - thinks it's doing something

For a long time, I thought it said Toms Trouble. The mind will make some things up as it goes

It sure looks like one. Clipped corner, rectangular holes look like they might be in the right pattern from what I remember.

I'm outside the punch card era, but they did teach about them in college (majored in computer science). When I was a kid, my dad worked in a bank data center. They had them there too, but were being phased out.

I have only installed let in's once. It was detailed in some set of prints the home owner bought from a plan mill.

Haven't run into 1x's diag. sheathing on older homes yet. Sub flooring yes. Usually 3/4 ship lap or 3/8's ply on ext.

Re: Sheetrock On The *exterior* Of A House?


The commercial job I've been at lately is being sheathed with a fiberglass mat gypsum sheathing called denseglass.

Kind of ironic seeing the roof being covered with this stuff because it has "not for roofs" printed all over it. I'm thinking it's probably labeled that way because people could have it break underneath them? On this job it's laid over metal decking so maybe it's acceptable?

That looks better than my last house did in 2003... It was stucco and one whole side of the house was only 2x4 framing with black paper and then the screen for stucco. It was a track house in Sunnyvale, Ca. I questioned it when it was being built, and I was told it was to code. I would have thought every wall would have to have OSB especially on a house that was almost $900,000..

Re: Sheetrock On The *exterior* Of A House?


I think that gypsum would be better than the stupid foil faced foam board I am finding around here. They did the metal strapping for rack and then just used the foam, heck most of the houses seams were not even taped. These houses were built in the 90's, big boom area and build it fast/cheap was the moto.

Now the lack of flashing, proper sealing are starting to rear their ugly heads...well consitant flow of jobs I guess. Plus that foam board did not stand up to water/rot very well, nothing really does but house wrap would have at least created another plane for the water to run down and not infiltrate. Granted it would not have been flashed correctly anyway.

The times I have done siding work on these, I quote taking off the entire side and installing OSB and house wrap. Anytime you try and pull nails or anything, stupid foam breaks apart and comes out in pieces. Hate that stuff

Re: Sheetrock On The *exterior* Of A House?


I have seen it a couple of times also. Both times it had black paper on it. Don't know the purpose for using it though, because as I recall the time frame the two houses were built, was a time when plywood was fairly inexpensive. And I don't think osb was available yet. Seems to me that a builder could have a real nightmare if the walls were up and they got into a rainy period.

Re: Sheetrock On The *exterior* Of A House?


We've had the privilege to working on a number of 70's era homes that were built with the white paper gypsum and I remember 22 or so yrs ago the first time I saw it I was like WTH is going on? Did some asking around, found it was a common way to save some money back in the day. As mentioned all we worked on had either metal/wood let in bracing on the corners or newer builds used plywood cdx on the corners.

Depending on how well the home/apartment units were maintained, some were in still like new condition, other's had severe deterioration from failed window/door flashing/caulks. Like most on here, we would cut and replace with 1/2" OSB when dealing wiith compromised area's.

Funny part is there's no real fire threat here in corn country, have never worked an area that had places stacked on each other, usually it's been acres between building or in town 10-40' gaps between units..so I have to think it was just a new technique for that time that everybody jumped on....while some builders didn't stray from the tried and true 1x8/10/12 sheeting covered in tar paper that was also a common practice before the gypsum era.

I know you've seen illustrations and stock photos on this thread, but here's a real life view, on another thread while discussing a totally different topic.

Oddly enough, I'm remodeling my kitchen and I came across this Friday night while re-routing the cables that were hanging in the old soffett.

An example of the cut in 1X4 racking brace. This one isn't on the corner due to a window in the power room.

It also looks like it has some pretty deep water stain, especially along the corner where the roof gutter system is located - My best guess would be leaks that seeped through somehow and kept in moisture for a while.

Water restant, fire retardant gypsum board, that is.

Still used today, although not so much around these parts anymore.
The trend now is more toward insulation board.

This is the product I see used on commercial work. Around here (N.w. Indiana) it has a yellow surface to it.Looks like a fiberglass mat. Although,I think it is labeled Denseshield,probably same product though.

Re: Sheetrock On The *exterior* Of A House?


Our house was built with this stuff. Black faced drywall on the outside. They used Tin test on the inside of the walls for plaster backing inside the house. Stupidest thing I have ever seen. Pain in the ass to repair too. I would love to rip it all out and re do all the plaster work in our house just to get rid of the crap.

Dens shield and dense glass are the same thing just different companies that make it.

They are actually both made by Georgia pacific. Dens-shield is tile backing and dens-glass is sheathing.
