Enclosure Advances Address Severe Weather

By C.C. Sullivan

Mark Twain remarked in 1897 that “while everyone talked about the weather, nobody seemed to do anything about it.”
Things have changed. Ever since the 2005 season – which brought the United States more than twice as many named storms and hurricanes as in an average season, according to NOAA’s Climate Prediction Center – building professionals, product manufacturers, and codes officials have worked to produce tougher buildings. New techniques and regulations introduced since the year of Katrina make buildings better at resisting projectile impact, wind-driven rain and high pressure differentials.
This has been driven in part to protect human lives, as well as to stem financial losses. According to the National Association of Home Builders (NAHB), Washington, D.C., seven of the 10 most costly natural disasters in the United States have occurred since August of 2004. Insurance companies have paid out a staggering $40.6 billion in claims in six different states due to Hurricanes Katrina and Rita alone.
Experts such as Dr. Robert Hartwig…

Airing Out: More Codes Call for Air Barriers


Have you specified any air barriers lately? If not, chances are you will soon. Recognizing the role that air barriers play in increasing energy efficiency in buildings, more codes are now including building envelope provisions. New rules concerning air barriers have taken effect in a growing number of municipalities and in states like Massachusetts, Wisconsin

and Michigan. The International Energy Conservation Code (IECC) also calls for air barriers, and several federal agencies now require them.
Up to 40% of energy used to heat and cool buildings, says the Department of Energy, results from uncontrolled air leakage. Air barriers can conserve energy by 30% to 40% in heating climates, and 10% to 20% in cooling climates…



Ways to Win: Condensation Design Strategies

For more reliable envelope designs use an integrated approach. This includes:

1. Control Driving Forces. Reduce the forces that drive water vapor through the envelope. High humidity levels in the ambient air should be reduced through dehumidifi cation and/or mechanical ventilation. Mechanical systems should provide complementary pressure control to minimize condensation potential.

2. Select Durable Materials. Building envelope materials located at potential condensation planes should not be…



Thanks! Barry.

Great Info.

Detail’s Detail’s

Hey, Carl;

Add this to your library of info, it will come in handy when you start your consultation Bussiness for the Proper installation of Stucco. Hint:) :smiley:


That means I would have to wage WAR with the fine folk’s at


Window installation and flashing detail’s cause more damage than stucco even if it is not installed to ASTM spec’s!

IMO of course

To many FAUX product’s on the market!

And FAUX spec’s by material mfgrs.

Then their is the FAUX labor pool.:roll:

And the FAUX inspection’s by city code’s inspectors.:twisted:

IMO of course!

**I need to stop now my vision is blurred.:twisted: :twisted: **

Well, maybe it is time for a bunch of us to colaborate and address the Faux’s
and make it correcteaux.!

What a debate that would make Eh!:slight_smile:

  1. Sill pans that exit the water to the exterior of all claddings!

  2. http://dryflekt.com/ On all claddings!

  3. Windows with trim around them flashed in 3 places to the outside of the trim not just the window width.

  4. No taping of horizontal joint’s of moisture barrier’s!

Just for starters!

That is a good start, now maybe we can just keep adding to it. :slight_smile: :smiley:

What a debate that would make Eh!:smile:

Might not be pretty!

How can a window be called self flashing?

When it has no end dams? Yet they call for end dams on flashing’s.

I never seen a self-flashing window, yet. :slight_smile:

Carl, check this out and let me know if you agree with this procedure.


Marcel:) :smiley:

No !!!

Well, that was short and sweet.

So which way is your preference?

Marcel :slight_smile: :smiley:

I gotta leave for a while when I get back

Sounds like a big cluster FAUX. :mrgreen:

Hi. Rick, hope you doing well.

I think Carl is out and about pondering and mulling this faux problem over. :slight_smile: :smiley: :wink:

Ok Carl, now look at this one and tell me if you like it better.


I think this one is more in line with your thinking. Maybe ha. ha. :slight_smile: :smiley:

I like tyvek’s flex wrap for the sill’s buttttttt !

It is reverse lap on the sides of the opening and it needs to have 1/2 that is not sticky so the next layer of moisture barrier for the stucco application can be properly lapped to kick the water out.

It is my understanding that tyvek fails the boat test so why would they allow the water to get between the layers?

And in the video the wrap was their stucco wrap.

For starters.

IMO That pdf is for the most part FAUX IMO

Where do you think the bulk of these pictures came from?


I can still go out any day of the week and take lots more! So even tho they put that together they still do not get the big picture. If it was my house and it was put together as per that document I would sue the hell out of JOCO.

you just can’t please some people…lol…
