Hermetically Sealed Sliding Door

Hermetic refers to the air-tight property that the seal of the door poses. So Hermetic actually means air-tight and spoiler alert: if air isn't getting in through it, nothing else is, not even a spec of dust… which is quite fitting because that's exactly what a hermetic seal was designed for.A sliding glass door, patio door, or doorwall is a type of predominantly glass sliding door, in architecture and construction, that is situated in an external wall to provide egress from a room and access to a backyard or patio, providing "a pleasant view" and, when not fully covered, passive daylighting.
