Application and Advantages
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.
Because PA66 is a hydrophilic substance, it will absorb the
surrounding water. The rate and amount of water absorption depend
on the ambient temperature, ambient humidity and storage period.
The relative humidity is higher in summer than in other short-term
storage seasons. High moisture content (more than 2%) will affect
the quality of wear-resistant strips.
When the insulation single bundle is removed from the shelf, it may
be deformed. If it is not straightened in time, it will cause
permanent deformation.
Therefore, it is recommended to keep it horizontal in a ventilated
and dry environment, pay attention to waterproof, stay away from
heat source, avoid stress and minimize bending.
