CARDINAL IG COMPANY
Unmatched Durability
and Performance
Endur® Warm Edge IG: Endurance Meets Thermal Efficiency
Endur® IG’s seal failure rate after 20 years is the lowest in the industry. Cardinal has over 400 million insulating glass units under warranty. To reduce IG unit seal failure, we know how to keep it low.
Cardinal’s warranty for our stainless-steel spacer IG units is the longest in the industry. For window manufacturers, our warranty is a safety net of reliability for their IG investment.

This graph contrasts the failure rates of legacy products and current Cardinal IG technologies. Cardinal drastically cut IG unit failures after the 1978 introduction of dual-seal silicone. Thanks to continuous research and development, Cardinal is setting a new standard for IG unit durability with Endur.

This graph contrasts the failure rates of legacy products and current Cardinal IG technologies. Cardinal drastically cut IG unit failures after the 1978 introduction of dual-seal silicone. Thanks to continuous research and development, Cardinal sets the standard for IG unit durability with Endur.
Cardinal subjects IG units to the demanding P-1 test to determine long-term seal durability. Test criteria simulate worst-case, real-world scenarios: 140º F, constant UV exposure and 100% humidity.
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).
Endur Makes Your
Window Job Stay Done
Early IG unit failures can wipe out profit margins. Warranty repairs cost dearly in labor, materials, and diminished customer satisfaction. But with Endur, you reduce your risk of costly service visits.
Our incredibly low failure rate means that warranty repairs for seal failure are a rare event. But in the case of failure, we’ll back you up unlike any other glass company. Your IG investment is guaranteed for 20 years, with up to a 150% credit warranty. There is simply no other company willing to match that level of risk.
A New Generation
Spacer Design
Endur IG spacer is an upgrade to our previous-generation XL Edge.
Endur’s patented warm-edge spacer design delivers enhanced condensation resistance and a 1-2 degree improved sightline temperature.
The corrugated shape adds strength. Unlike notched or open joints, the bent corners form a continuous impermeable metal barrier around the entire perimeter, keeping moisture out and argon in. Overlapping seams along ears allow breathing. The new spacer is also more aesthetically pleasing.
Finally, our Endur IG unit can improve overall window U-Factor up to 0.005 – a big deal when chasing the last 0.01 decimal for compliance to energy code.
More Than Just a Spacer
The components of Endur IG’s design render the highest performance and durability improvements.
Spacer:
Stainless steel spacer features a roll formed design to provide maximum area for primary and secondary sealant coverage. It provides increased resistance to condensation and less stress on the IG seal system. No polymer content minimizes the risk of chemical fogging.
Primary Seal:
Polyisobutylene (PIB) minimizes moisture permeation, is UV resistant and provides an outstanding argon barrier.
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.
Secondary Seal:
Specially formulated silicone provides long-term adhesion, withstands UV exposure, and provides excellent durability when exposed to moisture. Silicone also provides structural integrity.
Made for Thermal and Solar Efficiency
Endur insulating glass is fabricated with Cardinal’s industry leading LoĒ coatings.
We offer a variety of standard LoĒ and room-side LoĒ coatings to augment thermal efficiency, lower solar heat gain, and meet stringent performance standards.
Northern US and Canada
For the greatest thermal comfort under winter conditions, Cardinal produces triple-pane Endur IG units starting as thin as 7/8” or almost any glass and spacer thickness combination.
