What is polyamide insulation?
Polyamide is a plastic that insulates more than 500 times better than aluminum, so thermal break profiles have a much lower Uf value – and transmit much less heat or cold. As a result, a building stays warmer in winter while keeping the heat outside more easily in summer.
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.
The shape C thermal barrier polyamide strip can prevent the window
frame from dust and water, has a better mechanical performance, is
the first generation and easiest shape of insulating strips.
For the shape C, we can provide the following size or customize
according to customers' requirements.
They provide a better thermal insulation
They need lesser use of metals
The polyamide strips are cost-effective
They are easy to create thermal barriers with
They help in resources to be conservedand can reduce operating costs
They ensure maximum stability of the structure
They are more than effective in resisting condensation
They don’t require any special handling or fabrication
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.

1. Sample water content less than 0.2% by weight.
2. Norm laboratory condition:(23±2)ºC and (50±10)% relative
humidity.
3. The specifications marked with "a" only applies to I-shape strip
otherwise, the specifications concluded between supplier and buyer
through consultation, shall be written in contract or purchase
order.
Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.
For all shapes, they could be packed in linear, the length will be 6 meters or customized.
For the some simple shapes like I shape and C shape, they can be packed in rolls. Usually the length of one roll is around 400-600 meters.
