La description
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 nations annual energy supply. Related information on Europes
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. Its 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.
When looking to thermally upgrade the external fabric of the
property traditional insulation types could potentially mean adding
150mm of PUR insulation to the exterior of the property. This
approach could be problematic where there are space limitations. By
adding such a thickness eaves details, guttering, downpipes, window
reveals can all be problematic.
By utilising Vacuum Insulation Panels (VIPs) these issues could be
overcome. With a thermal conductivity value of 0.002W/mK (aged
design value) VIPs could offer up to a 7-10 times reduction in
insulation thickness compared with a traditional PUR solution.
Due to the nature of Vacuum Insulation Panel technology the key to
an external wall insulation system is how to fix the VIPs in place
without fixing through them and thus puncturing them. As the
neighbouring details show a matrix of traditional insulation
battens is first fixed in place to the exterior of the property.
(Vacuum Panels are a made to measure product so a specific panel
configuration can be designed for any property). These battens
create openings for the VIPs to sit within and then a secondary
layer of traditional insulation is laid over the top of the VIPs
and fixed back through the underlying battens. This secondary layer
offers a protection to the VIPs and also provides a bed for the
final finish of the property such as a render system.

The application of VIP in construction field will significantly
reduce the thickness of the walls and guarantee the best thermal
effects, because VIP are 7-10 times better than the traditional
insulation materials in heat insulation.
High performance thermal insulation can be used in various
components of the exterior building envelopes.
Vacuum Insulation Panel (VIP) offers a great new opportunity for
the thermal insulation industry.
Supertech is in the forefront of VIP technology research and
application.
