Product Description:
Thermal Break Strip is a kind of polyamide strip specially designed
for heat insulation purpose, featuring high strength, corrosion
resistance, heat resistance and high temperature resistance. It has
a wide range of applications in the insulation industry. The
material we use for thermal break strip is PA66GF25, which ensures
its performance at temperatures up to 240℃. It can also be
customized to meet the customers' specific width requirements.
Thermal break strips are widely used for thermal insulation of
refrigerator, air conditioner, and other appliances due to their
excellent performance.
Features:
- Thermal barriers reduce heat loss or heat gain through the
aluminum.
- Thermal barriers improve the U-value characteristics of finished
systems.
- Thermal barriers are about energy conservation, U-values and
government codes
- 70 percent of aluminum fenestration systems produced in North
America contain a thermal break
- Primarily used in colder climates to reduce heat loss
- Increasing use of thermal barriers to reduce heat gain and also
reduce heat loss
- Developers, architects and designers are demanding better
performance in terms of power usage
- Stricter government regulations to reduce power usage in buildings
to combat environmental concerns
- Aluminum, if it is to retain its market superiority in terms of its
structural integrity, will have to achieve better performance in
terms of U-values
- The use of thermal barriers will assist manufacturers to achieve
improved LEED performance

Applications:
Aluminium window has the disadvantage of limited thermal
insulation. Its Uf value, which indicates the amount of heat that
passes through a window profile, is simply too high. If your
windows have standard aluminium profiles, your home may develop
condensation, or even mould. Besides the resulting high repair
costs, household mould also aggravates respiratory problems such as
asthma.
But that disadvantage has now been completely eliminated if you
install polyamide strips in aluminum windows. In fact, thanks to
the development of a new invention known as thermal break profiles,
aluminium is at least as good as its competitors. In these
profiles, produced with specialized machines, a polyamide strip is
placed between the inner and outer sections of the profile.
Polyamide is a plastic that insulates more than 500 times better
than aluminium, so thermal break profiles have a much lower Uf
value - and transmit much less heat or cold. As a result, your home
stays warmer in winter, while keeping the heat outside more easily
in summer.
