I know that Latinos should learn English. I know and believe this as much as anyone, so let's just get this point out of the way. Perhaps someday I'll write an article in Spanish about the subject so you can hand it to your Hispanic employees but for right now I want to invite you to open your mind to consider why and how you should learn this language.
For the last three installments in this continuing series (parts four through six), we discussed gypsum-based sheathing. Prior to that, we discussed wood-based sheathing and the uses, purpose and environmental characteristics of sheathing materials. This month, we'll take a look at cement-based sheathing.
We appreciated Jeff Syken's Green Thumb column "Cover Story-Part Five" (September, Walls & Ceilings) about the benefits of USG's Fiberock Brand Aqua-Tough Sheathing products. As he accurately points out, these products were introduced in early 2000.
WUFI is an acronym for "Wärme und Feuchte Instationär." What's that? In English it means "transient heat and moisture transport." Does that make more sense? How about this: WUFI is a two-dimensional transient wall system hygrothermal simulation program.
Lack of integration between windows and the building weather-resistive barrier is a systemic problem in many buildings that often leads to leakage within a wall system. Consequences of improper integration typically include leakage, damage to interior finishes and deterioration of wall components, such as sheathing and framing.
When it comes to implementing new technologies and designs, colleges and universities are often recognized as trendsetters. This includes building products and materials, which are put to the test on campuses across the country and if they work-and work well-designs, planners and developers incorporate them into a variety of products.
Because glass-reinforced gypsum has been such a familiar item for more than two decades, not a lot of education about it goes on anymore. Consequently, many people who have come into the building industry recently don't understand exactly how the material works mechanically or appreciate why it is a standard for exterior building sheathing. Here are some useful facts about glass-reinforced gypsum board.
When we prepare a proposal, it must be based on something specific. For example, we prepared a proposal for a three-story college building project. The wall type schedule specifically called out 31⁄2-inch 20-gauge metal studs 16 inches o.c., for walls extending to 17 feet, 6 inches. However, the engineer required deflection criteria of L/240.
First, you can go to New Orleans right now and have a good time, at least in the popular tourist areas, which look like nothing ever happened. But if you drive a little way from those restored areas, it's a different story. There are blocks and blocks of abandoned single-story houses and there are shopping areas that look fine, except a lot are not open. These buildings are in the areas that were flooded and stayed submerged.
Fundamental theory in cladding integrity prevents liquid water from penetrating vertical walls, ideally through appropriate materials selection, architectural detailing and professional installation consistent with specifications and construction documents.
