Double-pane windows use two layers of glass with an insulating gap and are the standard for most Southern California homes. They offer strong energy performance at a reasonable cost.
Triple-pane windows add a third layer of glass and a second insulating gap for additional efficiency, but they cost more and are heavier. In Southern California's mild climate, the added benefit of triple-pane is often smaller than in colder regions — though it can still make sense for specific high-exposure or noise-sensitive situations.
For most local homeowners, double-pane with Low-E coatings offers the best balance of performance and value. We help you compare during your free estimate.
