product: AtticWrap; ThermaWrap
manufacturer: DuPont
web: construction.tyvek.com

Adding to the company’s line of weatherization systems for residential construction are Tyvek ThermaWrap and Tyvek AtticWrap. The former is a breathable insulating membrane des-igned to combine thermal resistance and high-vapor permeability. It helps control condensation and mold, and when installed with an air space, offers R-2 insulation value. Where previous generations of radiant barriers were made solely of aluminum foils, ThermaWrap features an aluminum layer that permits vapor to pass through. AtticWrap is a breathable roofing membrane that seals the building envelope, saving on heating and cooling costs. The material faciliates ventilation on the roof, allowing moisture to escape while locking out water and air.

product: DensGlass Ultra shaftliner
manufacturer: Georgia-Pacific
web: gp.com

Consisting of a moisture-resistant, noncombustible, one-inch gypsum core with coated glass mat facings, the DensGlass shaftliner helps prevent the growth of mold in moisture-prone vertical and horizontal shaft wall assemblies, stairwells, and area separations, while meeting the fire-resistance requirements in these spaces. When manufactured and tested in accordance with ASTM D3273, the product scores the highest level of performance for mold resistance. It also carries a warranty against delamination and deterioration for six months of normal weather exposure from purchase date.

product: residential framing system
manufacturer: USG
web: usg.com

This light-gauge steel framing system is intended to serve as an alternative to the traditional wood "stick" building methods used for residential architecture. The components—roof trusses, walls, and floor panels—are factory manufactured and can be incorporated individually or as a complete framing system. In contrast to wood, the steel will resist fire, mold growth, and termites and eases the installation of conduit.

product: Powerwall NExT
manufacturer: Sto
web: stocorp.com

Used under cement stucco, Powerwall NExT (New Exterior Technology) protects against air and moisture intrusion and mold growth using Sto Guard, a combination of a flexible joint treatment, a polymer coated glass fiber mesh, and waterproof coating. According to the manufacturer, Sto Guard protects over 28 times longer than conventional building paper.

product: PermaLath
manufacturer: Degussa
web: degussawallsystems.com

A nonmetallic glass-fiber-reinforced lath for 3/8-inch- to 1/2-inch-thick stucco applications, PermaLath responds to many of the drawbacks of metal lathing systems—namely, their sharp edges, inflexibility, and tendency to rust. The product can be applied both vertically and horizontally, and comes in wide rolls for fewer overlaps. Though PermaLath is appropriate for stucco up to only a 1/2 inch thick, the company is currently developing a product for 7/8-inch applications.

product: Custom Brick
manufacturer: Dryvit
web: dryvit.com

Bricks pressed by hand into wooden molds are too expensive for most projects. And yet, historicist work is everywhere—newly constructed apartment complexes intended to emulate old industrial-style loft buildings, for example. The finish application Dryvit calls Custom Brick is a more economical solution, easily applied in a multi-step process: one material achieves the grout color; a second is applied over a template and the grout coat. The template is then peeled off while the material is wet. Other benefits include a substantially lighter building facing than brick, which can lead to savings on foundation and structural requirements; and, used in combination with other Dryvit products, a more impact-resistant, energy-efficient EIFS system.

product: EmeraldCoat
manufacturer: Sto
web: stocorp.com

Nontoxic and VOC compliant, EmeraldCoat combines with Sto Guard Mesh or Gold Fill products to create a waterproof,
air-barrier system that can be rolled or sprayed directly on wall sheathing. Intended for the field-mixed stucco market, the coating breathes, allowing moisture to escape the wall cavity to prevent mold and rot. Unlike paper backing systems, EmeraldCoat's fluid application eliminates both tears and mislapped seams, and reduces degradation caused by exposure to weather during construction.

product: WeatherProtectR
manufacturer: Owens Corning
web: owenscorning.com

Designed for use with polystyrene foam applications, this moisture resistance system creates a secure air envelope that promotes better indoor air quality. It comprises three parts: a WeatherProtectR membrane, a WeatherProtectR P water-based primer, and a WeatherProtectR M mastic. Because it doesn’t degrade polystyrene, WeatherProtectR Waterproofing System can be used with the Owens Corning FOLD-FORM insulated concrete forming system—or other polystyrene foam insulation—to protect against heat loss, moisture penetration, and air filtration. It does not require tar or adhesives, needs no special equipment for installation, and is also compatible with any structural concrete, masonry, wood, plywood, metallic, or plastic surface.
