Vacuum insulation panel for green building wall insulation

Model Number: SUPER TECH VIP-006 Brand Name: SUPER TECH VIP Key Specifications/Special Features: Conservation of energy has become very important as energy costs continue to rise. Consequently, building energy conservation has emerged as a key area of research and development.The operation of buildings in the United States alone uses almost forty percent of the nation’s annual energy supply. Related information on Europe’s annual energy supply also show that building space heating and cooling demands about the same percentage of energy consumption.Many materials and applications have been used to insulate buildings. There have been some improvements in recent years as new materials are emerging with some having better insulating properties but with higher cost. A recent example is Vacuum Insulation Panels (VIPs). This is an effort to implement vacuumed space in thermal boundary walls for substantial insulation.Studies have shown that for the same thickness, the thermal resistance of an evacuated insulation is up to ten times better than conventional insulation materials such as fiberglass, polyurethane and polystyrene.

There are three modes of heat transfer: conduction, convection, and radiation, and if we remove most of the air molecules from a space—as occurs when we draw a vacuum—we largely eliminate the first two of those heat transfer mechanisms.

Conduction is the flow of heat from molecule to molecule. It’s the reason a cast iron skillet handle heats up, but thermal conduction also occurs across a layer of air, as kinetic is transferred from one air molecule to the one next to it. If we remove most of those air molecules by creating a vacuum, there will far less conductive heat flow.

Convection is the transfer of heat by moving molecules from one place to another. Warm air rises, and these convection currents carry heat—for example, this is the primary means that heat is delivered to a room from baseboard convectors (often called radiators). In a vacuum there are far fewer air molecules so convection of heat nearly stops.
