Architects and contractors are choosing DuPont’s high-performing building envelope solutions to construct buildings that meet and exceed expectations.
A high-performance envelope doesn’t need to be complicated. DuPont delivers stout exterior wall systems that are easy to install. Let us understand each one of these.
Thermax™ Wall System (TWS)
The DuPont™ Thermax™ Wall System (TWS) is more than an insulated wall – it’s a systematic approach to achieving efficiency at every level: simplified design, streamlined construction and optimized energy consumption for a reduced carbon footprint.
Steel transfers heat amazingly fast – up to 300 times faster than wood studs and reduces the effective R-value of metal stud wall designs by 40–60%. The ASHRAE prescriptive continuous insulation requirements for steel-framed, above-grade walls recognize this phenomenon, and in most climate zones, call for a layer of continuous insulation (ci) to be added to the assembly to help stop the steel thermal shorts that can decrease the energy efficiency of the wall system.
To meet continuous insulation code requirements it is critical to also account for condensation within the wall assembly. Even if a wall is adequately designed to prevent liquid water from entering the assembly, condensation can still occur as a result of the interior and exterior temperatures as well as relative humidity.
DuPont’s Thermax™ Wall System combines the strengths of powerhouse solutions to deliver a total package of benefits including:
- The insulating power of Thermax™ Brand Insulation
- The air and moisture protection of weatherization technology such as LiquidArmor™ Flashing and Sealant
- As an optional component, DuPont-approved spray foam in the stud cavity for added air and water sealing
The combined Wall System meets all applicable IBC and ASHRAE requirements for continuous insulation, moisture mitigation, air sealing, and vapor barriers. This system eliminates the need for exterior gypsum sheathing, applied air/vapor barrier membranes, and extensive site coordination, making it both cost effective and easy to install.
A stout weather barrier for commercial building envelopes, Tyvek® CommercialWrap® controls air leakage, stops water infiltration, and prevents mold by allowing water vapor to escape.
An air and water barrier made to stand up to the rigors of commercial job sites, with high tear-strength, durability, and up to nine months of UV resistance. DuPont™ Tyvek® CommercialWrap® building wrap is one of the easiest ways to make a significant difference in energy efficiency and overall building performance. Tyvek® CommercialWrap® can help in three vital areas, as part of a building envelope system:
- Controlling air leakage, which can impact the efficient operation of HVAC systems, costing the commercial building sector billions each year.
- Preventing water infiltration, which can reduce the effectiveness of insulation, and cause wood damage and corrosion.
- Allowing water vapor to escape when moisture does get in, letting wall systems dry, helping prevent mold, and protecting and improving building air quality.
