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.
Currently, there are two principal types of thermal barriers: polyamide thermal barrier strip and pour & debridge (P&D).
Our company only produce polyamide thermal barrier strip.
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.
As an energy-saving, polyamide thermal break profile is the best thermal break material for aluminum profiles connections. Boasting high compressive strength, polyamide thermal break profile is a premier thermal bridging solution that won't compromise a structure's integrity.
high quality, competitive price, free sample support and short lead time, high mechanical strength, high toughness, high softening point, good wear resistance, self-lubrication, long-term work at higher temperatures, high CTI value, excellent electrical insulation, low smoke and toxicity characteristics.
It is mainly used in insulation broken bridge aluminium products, helping to reduce heat loss or heat gain through the aluminum, and has better performance in terms of power usage.
