Improving Insulated Glass Performance with Super Spacer

Modern day insulated glass units often include a window spacer that maintains the space between window panes and creates a tight seal around the edges of the glass. Window spacers are designed to improve the energy efficiency of insulated glass units. These spacers are made of a variety of different materials, such as galvanized or stainless steel. Any sealed window unit that utilizes a material that is less conductive than aluminum is considered a “Warm Edge” technology window. Because these windows often still contain metal, the anticipated insulating properties may be compromised. In fact, over half of a window’s R-value (the capacity to resist heat flow) can be lost through metal window spacers.

Window Performance Problem

Super Spacer® is the answer to this modern-day problem. The unique, metal-free construction of Super Spacer window spacers eliminates heat loss through conductivity to create a stronger, more efficient window overall. Unlike traditional single-seal units, all-foam Super Spacer window units contain two sealants in one. The structural foam holds the window unit together while the barrier sealant reduces heat loss and protects against the formation of condensation.

How Does Super Spacer Technology Work?

Because there are no metals used in the construction of Super Spacer window spacers, conductivity is eliminated. This means that the insulating properties of the window are maximized, keeping the temperature of your window edges consistently warmer (up to 10.2 degrees warmer). While many other window manufactures claim to provide this “warm edge technology”, they often feature highly conductive metal-based glass spacers. Windows that include metal-based spacers can lose up to 50% of the overall R-value, allowing hot and cold to freely flow through the window seals. With Super Spacer, however, the R-value a window is better maintained.

How Does Super Spacer Technology Work

The all-foam design of Super Spacer includes two sealant formulas working together to create a superior window seal. The polymer structural foam serves to hold the windowpanes together for long-term strength and durability, while the proprietary barrier sealant keeps insulating gases in your window and lowers the overall U-values of your windows. The result is a more energy efficient window that prevents condensation and reduces sound transmission.

The polymer foam used in the construction of Super Spacer window spacers improves the overall structural integrity of the insulated glass unit for long-term durability.

Super Spacer vs Metal Spacers

Metal does not have the same level of resiliency as foam does. Insulated glass units that include metal or rigid plastic spacers do not offer the flexibility that Super Spacer can. Super Spacer features a proprietary 100% memory formula, which effectively compensates for the natural expansion and contraction of materials in fluctuating temperatures.
