EndurTM Insulating Glass
Nothing endures like Endur IG.
Still the industry’s lowest failure rate
A New warm-edge, stainless steel spacer is key.
How much failure can you afford?
Assuming a $500 service call to reglaze a failed IG unit under warranty, and with an 8% seal failure rate, the window manufacturer would need to add $40 to the cost of the window to cover warranty costs.
With a 0.20% seal failure rate such as Cardinal’s, the window manufacturer would need to add just $0.50 to the window price to cover warranty claims.
Cardinal IG units excel in rigorous P-1 test.
Results showed that competitive seal systems failed within 8 to 22 weeks of testing. Endur IG, utilizing silicone dual-seal construction, routinely passes 80 weeks exposure with dew points below 0°F (-18°C).
Energy-efficient performance that endures for decades.
Cardinal IG units consist of two or three lites of glass separated by an inorganic metal spacer.
- Primary Seal: Polyisobutylene (PIB) minimizes moisture permeation, is UV resistant and provides an outstanding argon barrier.
- Secondary Seal: Specially formulated silicone for IG units provides long-term adhesion, is unaffected by UV exposure and provides excellent durability when exposed to moisture. Silicone also provides structural integrity.
- Spacer: Stainless steel spacer features a roll form design to provide maximum area for primary and secondary sealant coverage. It provides increased resistance to condensation and less stress on IG seal system. No polymer content eliminates the risk of chemical fogging.
- Desiccants: Beaded molecular sieve provides initial frost points below -65°F. Desiccant assures optimum moisture adsorption while minimizing the effects of temperature-related pressure changes.
