What is a thermal break strip?
Our Thermal Break Strip is specially designed to enhance the
performance of your aluminum doors and windows. By using our high
precision polyamide thermal break strip, you can enjoy excellent
thermal insulation and sound insulation properties. Say goodbye to
drafts and noise, and hello to a cozy and peaceful environment.
Our thermal break strip is inserted into the aluminum profiles of
your windows and doors, forming an integral part of an
energy-saving window system. It effectively reduces heat
conduction, helping you save on energy costs while keeping your
home comfortable.
Production Description
Over the years, polyamide heat-insulation strip has been widely
used in glass curtain walls due to its good properties and low
cost. Especially Polyamide 66 reinforced by 25% glass fiber thermal
break strips, they are inserted into aluminum window, door and
facade profile for thermal insulation.
The shape-C polyamide thermal insulation strip can prevent the
window frame from dust and water, also has a more beautiful
appearance than the shape I, but not so firm.
For the shape-C, we can provide the following size or customize
according to customers' requirements.
Our Service
1. Expertise in the production of standard polyamide thermal break
strips.
2. Respect customers' needs, provide customized products, try best
to satisfy customers' requirements.
3. Fast service and on-time delivery
4. Strict quality control system, each production process will be
strictly supervised by us.
5.We can provide all products on the insulation strip production
line and the technical support.
Advantages
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.The working temperature of the thermal insulation strip is 220°C,
Melting Point reaches to 246°C. This enables coating process after
assembly of composite profiles.
8.High corrosion-resistance, weather-resistance, heat-resistance,
alkali-resistance and long life of usage.
9.linear thermal dilation coefficient almost identical to that of
aluminium profiles.

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.
Storage Conditions
The strips will be stored in the ventilated and dry environment,
horizontally placed, paying attention to waterproof, keeping away
from the heat source, avoiding heavy pressure and the contact with
acid, alkali as well as organic solvent.
Packages
For all specifications/shapes, they could be packaged in linear,
the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed
in rolls. 400-600 meters/roll.
Delivery
We have the production capacity of 100000 meters per day. For
common specifications, we have molds , and will be shipped in 7-15
working days after receiving the deposit.
