Green Building

Green Building, whether in commercial or residential construction, results in greater material efficiencies, smarter construction practices, reduced energy consumption, and a more healthy living and working environment. While Green Building has many objectives, two of the most important are reduction of energy consumption and durability of the structure.

Reduction of energy consumption

To create an energy efficient structure, every part—from the foundation to the roof, the HVAC system to the lighting—must be carefully considered. The wall system in particular, with its numerous openings and exposure to both air and water, requires special design considerations, such as:
• Understanding the thermal resistance properties of different wall components   
   (cladding, wood, drywall, windows and doors, etc.)
• Using the best insulation for the wall system
• Sealing cracks
• Insulating the exterior of the wall
• Reducing air infiltration
• Keeping the wall dry
By correctly utilizing all of these components, an energy efficient wall achieves a specific thermal performance and maintains that performance level over time, reducing energy consumption and cost.

Durability of the structure

One of the most important ways to preserve the durability of a structure is through water managed wall practices. A water managed wall combines exterior cladding, secondary weather barriers, and flashings to defend against moisture infiltration, protecting the structure from water damage, mold, mildew, and rot. By minimizing water impact throughout the expected life of the structure, there is no deterioration of insulation, so thermal performance is also maintained over time.

Green Building

Whether you consider it Green Building or just good building practices, energy efficient and water managed walls are a sensible and smart goal of design. GreenGuard products help you achieve this goal. Our XPS (extruded polystyrene) products provide superior moisture resistance. They won’t absorb water, are not a food source for mold, and are not subject to moisture-related damage or deterioration, which means they retain their insulating properties over time. Our building wraps and flashings also help to protect the wall against water penetration and damage, and the wraps serve as an air barrier, enhancing thermal performance.

Several organizations, such as ENERGY STAR®, NAHB (National Association of Home Builders), and LEED (Leadership in Energy and Environmental Design), are at the core of the Green Building movement. These groups have initiated certification programs and guidelines that qualify building materials and practices as meeting or exceeding Green Building standards. Using GreenGuard products qualifies your structures for points under the NAHB Green Building Guidelines and the LEED-H and LEED systems.

LEED - Leadership in Energy and Environmental Design

GreenGuard XPS Insulation Products reduce building energy demand, dependent upon the amount of insulation used. GreenGuard Building Wraps reduce unwanted air infiltration into the wall cavity, thus helping to protect the insulative wall properties. All GreenGuard insulation products contain at least 30% post-industrial recycled content. All GreenGuard building wraps contain at least 5% post-industrial recycled content. For additional information, please visit the LEED website.

*Depending on the percent reduction in energy use based on ASHRAE/IESNA Standard 90.1-1999 or local energy code, whichever is more stringent.

*Depending on the amount of post-industrial recycled content.

*Dependent upon 20% of all materials being manufactured regionally, within a 500-mile radius of the project. GreenGuard XPS insulation and building wraps are manufactured in Winchester, VA.
