An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.

Insulated glazing (IG) forms a very compact multi-layer sandwich of air and glass, which eliminates the need for storm windows. Screens may also be left installed year-round with insulated glazing, and they can be installed in a manner that permits installation and removal from inside the building, eliminating the requirement to climb up the ...
Thermal conductivity of still air is 0.024 W/(m.K) and much lower than that of glass (0.96 W/(m.K)). [1] Factors which limit the performance of a double glazed window are gap width, convection within the cavity and radiative heat transfer across the gap which is largely independent of its width.

Cold air enters the bottom of the cavity, from the outside, is heated during transfer upwards though the cavity, and enters the interior space at the top of the cavity. More complex designs exist, which for example do not transfer ventilated air between the interior and exterior, or which have multiple ventilation channels.

The primary mode of heat transfer impeded by insulation is conduction, but insulation also reduces heat loss by all three heat transfer modes: conduction, convection, and radiation. The primary heat loss across an uninsulated air-filled space is natural convection, which occurs because of changes in air density with temperature. Insulation ...
