The Coeur d'Alene Window Company uses glass manufactured and assembled by Cardinal IG.

Endur™ Insulating Glass

A lot of manufacturers talk about performance, i.e., U-Factors and SHGCs. But what about durability? Performance over the long haul? That’s where Endur IG™ excels. Endur IG continues the Cardinal tradition of long-term performance. It delivers the industry’s lowest failure rate, the only comprehensive 20-year factory warranty plus outstanding thermal performance and solar control. Exceptional longevity and performance … that’s how we help protect your brand and your reputation. New Endur IG, what the future of insulating glass looks like.

Nothing endures like Endur IG.

 

With over 500,000,000 IG units under warranty, Cardinal knows a thing or two about building long-lasting IG units. Our units have proven themselves over and over in the field and in the lab. The only way we’d change a thing is if we could improve it. We have.

 

Still the industry’s lowest failure rate

Endur IG is built on the proven technologies that help Cardinal IG units achieve the industry’s lowest failure rate – only 0.20% over twenty years – allowing us to offer the industry’s only comprehensive 20-year factory warranty, because endurance is just as important as performance.

  1. Primary Seal: Polyisobutylene (PIB) minimizes moisture permeation, is UV resistant and provides an outstanding argon barrier.

  2. 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.

  3. 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.

  4. 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.
