Milgard Moving Glass Wall Systems bridge indoor and outdoor living with expansive floor-to-ceiling sliding glass doors. With 12 standard size options in three- or four- panel configurations, the product offers an accessible version of moving glass walls often seen in high-end homes, says the company. Featuring a fully weather-stripped structural interlock system, the glass walls come in two low-E options, including Milgard’s SunCoatMax glass for improved energy efficiency. Tandem stainless steel ball bearing rollers allow for the opening and closing of doors with the touch of a finger, according to the manufacturer.
