In addition to offering Cardinal IG as the primary source of insulated glass featured in our skylights and custom over-head glazings; we offer the same high quality glass products directly to our CrystaLite Dealers.
Silicones containing Acetoxy will attack the sealant of the unit itself and cause failure. Acetoxy is often listed as a base element in chemicals such as methyltriacetoxysilane. These sealants should NOT be used with IG units. Acetoxy-Cure has a vinegar smell that can be used to identify sealants containing this.
Neutral-Cure silicone is required and is commonly used. This list contains sealants that have been tested and approved to be used with IG units. If the sealant you use and prefer is not included in this list, it may still be safe to use. Please call or email and we will verify.Review Approved Sealants
Lost profits are unappealing to any window manufacturer, especially when due to warranty replacements caused by IG seal failure. Based on extensive research and experience, Cardinal estimates that the real cost for every glass unit a window company replaces is approximately $200.
This includes hard and soft costs for replacement windows, service calls, factory overhead, business disruption, and a damaged customer faith. At $200 per unit, how much could you and your channel partners be losing in the long run? Endur IG insulating glass comes with the lowest failure rate in the industry - developed in part from Cardinal's 45 years of experience in manufacturing IG units, 27 of these years utilizing a dual-seal silicone system.
We provide a 20-year guarantee on most Endur IG units because of our advanced design and fabrication; see warranty information for details. Endur IG is at the leading edge, incorporating a stainless steel spacer with airtight bent corners and a dual-seal construction of compressed polyisobutylene (PIB) and silicone.
Desiccants are contained in the spacer to eliminate any potential for moisture. Argon is filled inside the IG unit, improving window U-factor. Since Endur IG is a warm-edge IG, the possibility of indoor condensation is greatly reduced.
Cardinal's superior IG construction translates into a 0.2% seal failure rate over twenty years - plainly the lowest in the industry. To compare, the well-established 1976 Sealed Insulating Glass Manufacturing Association (SIGMA) study identifies average industry IG failures of over 9% in fifteen years. Modern competitive spacer systems simply cannot match the long-term durability characteristics of Endur IG IG.
When it comes to reducing solar heat gain from the blazing sun, LoE-340 simply has no equal. And because it’s not tinted, you enjoy a number of other advantages as well. First, there’s the cost savings of no tint. Then you avoid the disadvantages of tinting: the potential for thermal stress breakage and the potential need to heat treat the glass.
Tinted glass has several other glaring deficiencies. Regular tinted glass works by absorbing sunlight, so the glass becomes hot in the sun. The color of the glass also changes with its thickness. On the other hand, LoE-340’s appearance and performance remain the same regardless of glass thickness.
