What is a polyamide thermal barrier?
The polyamide strip is a mouldable composite material. Its fibers are oriented in all three dimensions to ensure appropriate strength. As such, manufacturers can use these strips across all types of fenestration, including oversized and impact-resistant systems. Therefore, polyamide thermal barriers are the best for thermal break windows.
What are the different types of polyamides?
Polyamide (PA) Polyamides are among the most important and proven technical thermoplastics, known for their heat resistance, stiffness and high mechanical stability Polyamides can be classified into different types, with PA 6, PA 6.6 and PA 12 most established on the market.
Our polyamide strips are made of PA6.6 reinforced by 25% fiberglass.
Polyamide thermal breaks are extruded in dry state but they absorb moisture from the environment after the production as time passes. Moisture level depend the following conditions:
- Ambient temperature
- Ambient humidity
- Storage period
During the summer time, when the temperature and humidity in storage area are higher than usual, the insulating profiles absorb more moisture than in the remaining seasons, even stored properly.
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.
