Agenda Vinyl window manufacturing Warm edge spacer systems and Low-E Glass NFRC and Energy Star Structural performance and product certification

The Great Differentiator**It’s the Glass Package…: 

The Great Differentiator* *It’s the Glass Package… 80% of a window is glass The battle will be won or lost through the glass Coatings Spacer Gas U Value

The Great Differentiator**It’s the Glass Package…: 

The Great Differentiator* *It’s the Glass Package… According to US Department of Energy and H.U.D. 70% of Heating Dollars 46% of Air Conditioning Dollars Are lost through your windows and doors

The Great Differentiator**It’s the Glass Package…It’s the spacer: 

The Great Differentiator* *It’s the Glass Package…It’s the spacer Traditional aluminum spacer systems are not warm edge design allowing conduction through the spacer that can lead to condensation New foam spacers provide a warm edge design but offer little to no structural integrity that can lead to glass slippage and failure with heavier units The Intercept Spacer System provide a warm edge design with a u shaped spacer that allows the insulated glass unit to flex without adding pressure to the glass that helps to promote a long-term solution.

The Great Differentiator**It’s the Glass Package…: 

The Great Differentiator* *It’s the Glass Package… The Intercept Spacer System 88% less conductive Warm Edge spacer reduces the chance for condensation Polyisobutalene sealant helps to isolate spacer from the glass to added warmth One-piece construction virtually eliminates failed corners while adding strength Warranted for Life Intercept Traditional Red is warm, blue is cold

The Great Differentiator**It’s the Glass Package…it’s the gas: 

The Great Differentiator* *It’s the Glass Package…it’s the gas Helium – Less dense than common air. Is not effective as an insulator. 2 HE 10 NE 18 AR 36 KR 54 XE 86 RN Neon - Less dense than common air. Is not effective as an insulator. Argon – 48% denser than air. Helps to slow down the transfer of heat through the space between the glass layers. .9340% of our atmosphere. Krypton – 209% denser than air. Insulates better than Argon. Is much rarer that Argon with only 1.14ppmv Xenon – 390% denser than air. Insulates better than Argon or Krypton but is very rare. With 0.09ppmy Radon – No let’s not use this one. It’s denser but Radon has some other issues… AIR Air – Just everyday Air, the most common of “gas” used in the production of insulated glass. Increasing Cost

Product Testing and Certification NFRC and Energy Star

National Fenestration Rating Council: 

National Fenestration Rating Council NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings so that: Architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices. •  Building officials, state government employees, and others involved in code development and enforcement can determine if products meet local codes. •  Government- and utility-run energy efficiency programs can establish performance requirements and standards. •  Manufacturers have a fair and level playing field to compare products and an accurate method of showing the energy benefits of new designs or technology.

National Fenestration Rating Council: 

National Fenestration Rating Council U-Factor U-factor measures how well a product prevents heat from escaping. The rate of heat loss is indicated in terms of the U-factor (U-value) of a window assembly. U-Factor ratings generally fall between 0.20 and 1.20. The insulating value is indicated by the R-value which is the inverse of the U-value. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value. Solar Heat Gain Coefficient Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both admitted through a window, both directly transmitted, and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits Visible Transmittance Visible Transmittance (VT) measures how much light comes through a product. The visible transmittance is an optical property that indicates the amount of visible light transmitted. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted. Air Leakage* Air Leakage (AL) is indicated by an air leakage rating expressed as the equivalent cubic feet of air passing through a square foot of window area (cfm/sq ft). Heat loss and gain occur by infiltration through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly. Condensation Resistance* Condensation Resistance (CR) measures the ability of a product to resist the formation of condensation on the interior surface of that product. The higher the CR rating, the better that product is at resisting condensation formation. While this rating cannot predict condensation, it can provide a credible method of comparing the potential of various products for condensation formation. CR is expressed as a number between 0 and 100. * This rating is optional and manufacturers can choose not to include it.

National Fenestration Rating Council: 

The National Fenestration Rating Council (NFRC) energy performance label can help you determine how well a product will perform the functions of helping to cool your building in the summer, warm your building in the winter, keep out wind, and resist condensation. By using the information contained on the label, builders and consumers can reliably compare one product with another, and make informed decisions about the windows, doors, and skylights they buy. NFRC adopted a new energy performance label in 2005. It lists the manufacturer, describes the product, provides a source for additional information, and includes ratings for one or more energy performance characteristics. The information contained on the label is also available in the NFRC's online Certified Products Directory. WWW.NFRC.ORG National Fenestration Rating Council

What is ENERGY STAR? : 

What is ENERGY STAR? ENERGY STAR is a government-backed program to help consumers identify energy efficient products. Every ENERGY STAR qualified window, door, and skylight is independently tested and certified to perform at levels that meet or exceed strict energy efficiency guidelines set by the U.S. Department of Energy. www.energystar.gov

Structural Performance Ratings : 

Structural Performance Ratings Product Certification and Testing Requirements

Slide22: 

Certification is a process that indicates that a product line has been tested, meets specified requirements, and is subject to ongoing inspections by an outside third party certification agency NFRC is the most recognized certification program (thermal properties). Hallmark is the brand name for WDMA’s certification program, which is a competitor of the AAMA certification program (air, water, and structural properties). Once certification is granted the manufacturer is allowed to label the product with a certification label. This is very similar to the NFRC certification program. The latest building codes (IRC) are now requiring certified product labels, and states adopting these new codes are beginning to enforce these labeling requirements. WWW.WDMA.COM Certification Programs

Slide23: 

Test Definitions Air Infiltration is the amount of air that leaks through a window while under a controlled pressure differential of 1.57 psf (25mph wind). The rating of the leakage is determined by dividing the recorded air leakage (standard cubic feet per minute - SCFM) by the square footage of the window. A residential window cannot exceed 0.30 SCFM/SQ.FT. Water Resistance is the ability of a window unit to not allow water to the interior of the home while under a controlled pressure differential, which is usually 10% of the design pressure (DP). The flow rate of the water is 5 gallons/square foot per hour. Structural Load is the ability of a window to sustain a large pressure differential (simulated windload) in both a positive (towards the home, a typical storm) and negative (away from the home, like a tornado or hurricane). The loads are applied for ten seconds in each direction. After loading, the window must function as designed, and deformation of any component cannot exceed .4% of its length. The structural load is 1.5 times greater than the design pressure for a safety factor. Design Pressure is the final rating that is given to a product. It is the pressure (windload) that a product is designed to withstand. All three of the above criteria must be meet to achieve a DP rating. Industry Test Standards
