What is the purpose of thermal break strips?

December 23, 2024

Thermal break is a reinforced polyamide strip (a non metallic, composite, structural, material) fixed between the inside and outside profiles, creating an insulated barrier within the window frame.

Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge Aluminum Doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision poly-amide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat conduction.

Product Advantage:

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.

Better Performance Than Other Types

The function of PA thermal break strip and the comparison of PVC thermal break strip.

1. The main raw material of PA thermal break strip is PA66 plus 25% glass fiber, and this material of PVC thermal break strip is PVC resin powder plus 25% calcium carbonate. Compared with PVC thermal break strip, PA66 thermal break strip has the following advantages:

(1) High tensile strength Nylon thermal break strip:≥126N/mm

PVC thermal break strip: about 70N/mm.

(2) High thermal deformation temperature PA thermal break strip: 240ºC PVC thermal break strip: 90ºC.

(3) It is more durable. PVC insulation strips are easy to age.

(4) Good self-extinguishing function.

Storage Conditions

According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.

So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)
