It's Not the Stucco
To the Editor:
I am so pleased that JLC was able to crack open the veil of
the stucco industry's secrecy ("Minnesota Building Official
Makes Waves With Stucco Warning,"
In the News,
10/03). Now we don't have to hide in dark alleyways and
underground bunkers any longer. The vast conspiracy has been
ripped open. It's true, it's all about workmanship. Early in
1987 we all got together and decided we would have a massive
paradigm shift in the way we completed our most basic of tasks.
In effect, we instructed everyone involved in the stucco
business to do everything bassackwards, just to see if we could
get away with it.
Now that I have your attention, don't you find it surprising
that these issues seem to correlate with a time in our history
when we were trying to make our homes more energy efficient?
Nobody (at least here in Minnesota) can provide a reasonable
explanation as to why we have to put plastic sheeting on the
inside of our framing, yet we are required to do it. Our
exterior walls are now constructed with 2x6s instead of 2x4s,
just to handle the extra insulation we are required to put in
them. And, is it any coincidence that at the same time we were
making our homes exceedingly more complex, we found OSB and
also made our windows more energy efficient and easier to mount
into rough openings with the introduction of nailing
flanges.
For our part, the Minnesota Lath and Plaster Bureau has been
perhaps more progressive than most in defining criteria for
properly tying in flashing issues with the installation of the
weather-resistive barrier. Not surprisingly, a sales rep for a
large window manufacturer in the area stops by our office once
in a while to pick up our instruction guide for installing
windows. Go figure, stucco guys telling window guys how to put
in windows!
If there was a paradigm shift in workmanship, it seems to be
particularly apropos as it applies to window installation.
Where in the evolution of construction was it decided that it
would be better to flash a window behind the exterior cladding
instead of over it? The purpose of flashing after all is to
keep water out at its most vulnerable spots. Instead of using
all of the gaskets and goop we now employ to weep water 6 feet
to 60 feet from where it is getting in, wouldn't it make better
sense to make a window that flashes over the cladding rather
than behind it?
The window manufacturers have been marvelous in making new
energy-efficient window products, but they have done us no
favors in making them easier to mount into a rough opening. The
simple fact is that there is still a lot of confusion about
proper installation, and the majority of the window
manufacturers continue to be evasive if not apathetic on the
issue.
Portland cement plaster (a.k.a. stucco) has been mixed and
installed in essentially the same manner for over 100 years. It
is as natural a building product as stone, wood, and brick.
When we start to question the viability of such a product, it
is time to apply the brakes and take an informed look at the
direction our building practices are taking us.

Lopsided Reporting
To the Editor:
I can't recall ever having seen such a one-sided and
thoroughly slanted hit piece done by a respected trade journal
as your article "Bucking Trend, California Picks NFPA Building
Code" (In the
News, 10/03). The only views presented to your audience in
the article were those of the relentless ICC propaganda
machine.
What kind of balanced news reporting was that? Perhaps some
insight from NFPA or IAPMO would have presented a more
encompassing article, one that delved into the real problems
with the ICC codes — why their full adoption has been
limited to a small handful of the 50 states, or what instigated
the disintegration of a long-standing amicable relationship
among the organizations involved.
Next time an ICC representative knocks on your door, please be
a little more skeptical, okay?

Step in the Right Direction
To the Editor:
I appreciated the article
"Doing Vinyl
Right" (11/03). The reason I hesitate to specify vinyl is
the generally poor detailing and poor workmanship. It seems
everyone is a "certified installer," but finding a truly
qualified installer is rare.
Two items in the trim section of the article show, however,
that there is still a way to go to match the crisp appearance
of wood. A true rosette (Figure 1) is square and would not have
a little corner nibbled out of it. Also, anything that is done
to get rid of the J-strip is great, but the caulk joint shown
in the installed photo in Figure 2 would be rejected by any
quality installer. Again, thank you for the step in the right
direction.

Preventing Hanger Corrosion
To the Editor:
Your news item "New Wood Treatments May Be More Corrosive"
(In the News,
9/03) was right on time: I'm rebuilding a deck using ACQ
framing. To combat any premature corrosion, I isolated all
metal framing connectors from the treated framing with pieces
of 15# felt. Each joist hanger needed two pieces, one applied
to the ledger board or rim joist, and one strip a few inches
wide wrapped around the three sides of the joist resting in the
hanger.
This probably added an hour or two to the labor of the deck,
but I believe it was time well spent and cheap insurance
against future problems.

Good idea. According to metal connector manufacturers,
stainless-steel hardware and fasteners (Types 304 and 316)
offer the best protection with ACQ and Copper Azole lumber.
G185 galvanized hardware (1.85 ounces of zinc per square foot),
such as Simpson's Z-MAX or USP's Triple Zinc is also
recommended. At a minimum, use hot-dipped galvanized hardware
and fasteners, but don't mix stainless fasteners with
galvanized hardware (or vice versa).

Privacy Protection for Mac
To the Editor:
I read with interest your article concerning privacy invasion
problems and identity theft on the Internet
(Computers,
11/03). While I realize most people use PCs, many of us use
Macs because they are generally better at handling graphics. I
looked up the web addresses you provided (ZoneAlarm, Grisoft,
Lavasoft), and not one of them supports Macintosh. I wondered
if you knew of anyone who might offer similar services for
Apple products?

Computers columnist Joe Stoddard responds: Thank you for
the question. We use Macs in the publishing world as well, but
unfortunately there isn't a lot of construction software
available for the platform, so I seldom cover it in my
column.
Many of the security problems PC users face are a direct
result of vulnerabilities in either the Windows operating
system or various other Microsoft programming environments
— Visual Basic, for example. Since these are specific
to PCs, you have a lot less to worry about as a Mac user. That
doesn't mean you're completely immune to problems, but I don't
know of any "free" Mac equivalents to the products I listed in
the article. The ones I've come across are hopelessly outdated
or just not effective enough to warrant a mention.
There's a pretty good list of commercial utilities for the Mac
platform at
www.macreviewzone.com/html/reviews/magazine/software/virus_and_security.php.
Best of luck.
Flashing the Tops of Deck
Joists
To the Editor:
I enjoyed the article on deck ledgers and found all the
details interesting. However, I noticed there is no allowance
for flashing for the tops of the joists. We use a self-sticking
bituminous membrane on top of all horizontal surfaces, because
it allows the nail or screw to self-seal, preventing water from
entering and rotting the tops of these joists. Any reason this
was left out?
Mark Labourdette, CR

You make a good point. Using a self-sealing flashing
membrane on top of the joists sounds like a good idea,
especially if you're using redwood or cedar joists, which are
common in the West. The assumption in the article was that all
the deck framing would be pressure treated, which is standard
construction in the eastern U.S. We should have labeled the
joists in our drawing accordingly. Thanks for the
comment.
