Duralite™ Insulating Glass Spacer System |
 |
All Sun insulated glass units use Duralite™, the highly energy efficient insulating glass spacer system developed by Truseal Technologies. This system provides superior thermal performance, excellent insulated glass seal and reduced condensation.
Duralite™ spacers are more efficient because they contain no metal. This means that your windows will be warmer in the winter and cooler in the summer, making your home more comfortable year round. With a non-metal spacer, there is less temperature differential, so less condensation is created, which can reduce the risk of unhealthy and unsightly mold growth.
The Duralite spacer system can save you money. The energy efficiency of a window can be measured by the amount of heat conducted through its materials. Duralite spacers conduct less energy than any other insulating glass spacer, saving you more money on your energy bills.
Key Features:
• Lowest Conductivity warm edge spacer
• Improved condensation resistance
• Easier to meet EnergyStar™ requirements
• Warmer edge of glass temperature
• Superior argon gas retention
• Proven adhesive technology
• Composite Laminating Technology
• Smooth surface appearance
Simulations were performed by Enermodal Engineering Limited using Window 5.2 and Therm 5.2 as per NFRC 100 and NFRC 500, 2001. Generic vinyl window, soft coat low e (e=0.034), argon filled.

Condensation Resistance No spacer system can eliminate condensation but Sun's High Performance warm-edge spacer system reduces conductivity by 50% over other warm-edge spacers. This reduces conductivity, which in-turn reduces condensation. |
Reduced Conductivity Sun's warm-edge spacer replaces the conductive materials used in other spacers with air. This unique concept creates a high thermal barrier to reduce the transfer of heat or cold through the spacer. |

Optimal Air Space Insulated glass gains most of its benefits from the insulating properties of the sealed air space between the two piece of glass. There is a narrow range in which the insulating properties are optimized for the thickness of the air space. If an air space is too narrow, the thermal conductance (air-to-air transfer) is too strong. On the other hand, if the air space is too thick, the transfer from convection (air movement within the air space) is too great. This means you want an air space that is thick enough to provide a good thermal conductance barrier, while still being thin enough to prevent loss through convection. Tests indicate that an air space of 1/2" to 9/16" is ideal for most residential windows. Sun uses a 1/2" air space on all of our insulated glass units.
