Poor quality insulation strips and leather strips have many hidden dangers. How to discern the right materials with discerning eyes?

When selecting building materials such as insulation strips and leather straps, it is indeed necessary to pay extra attention to the quality of the materials to avoid potential safety and performance hazards. Here are some suggestions to help you identify pearls and choose the right materials:

1、 Identify the hidden dangers and key points for selecting low-quality insulation strips

The hidden dangers of inferior insulation strips:

Unstable dimensional accuracy affects the sealing and insulation performance of doors and windows.

Poor aging resistance and short service life.

Low mechanical properties may cause deformation or damage to doors and windows.

Mismatch with the linear expansion coefficient of aluminum profiles, causing structural problems.

May release toxic gases, affecting indoor air quality.

Key points for purchasing:

Material selection: Prioritize using PA66 nylon insulation strips and avoid using PVC materials. PA66 nylon material has better heat resistance, toughness, and aging resistance. The material can be identified by the spray code markings on the insulation strip, while observing the color and toughness. PA66 nylon material has a dark color, a frosted surface, good toughness, and is not easily broken.

Shape and width: Common shapes for insulation strips include straight, C-shaped, T-shaped, and multi cavity types, with the multi cavity type having the best insulation effect. The width of the insulation strip is generally controlled between 20-35mm, and the specific width needs to be determined according to the regional climate and usage requirements.

Ingredients and process: Good insulation strips should use native materials and incorporate 25% fiberglass technology, with the PA66GF25 logo on the spray code. This type of insulation strip has better mechanical properties and aging resistance.

2、 Identify the hidden dangers and key points for purchasing inferior leather strips

Although the main focus of the issue is on insulation strips, when it comes to leather strips (such as used for door and window sealing, etc.), attention should also be paid to their quality:

The hidden dangers of inferior leather strips:

Poor elasticity and poor sealing effect.

Poor aging resistance, prone to hardening or cracking due to aging.

May contain harmful substances that can affect health.

Key points for purchasing:

Elasticity and toughness: High quality leather strips should have good elasticity and toughness, and be able to tightly fit door and window frames, achieving good sealing effect.

Aging resistance performance: Select leather strips that have passed aging resistance testing to ensure that they are not easily aged, hardened, or cracked during long-term use.

Environmental friendliness: Pay attention to the material composition of the leather strip and avoid choosing products containing harmful substances to ensure clean and healthy indoor air.

3、 Summary and Suggestions

When choosing insulation strips and leather straps, it is recommended to:

Choose well-known brands and manufacturers: Famous brands and manufacturers usually place more emphasis on product quality and after-sales service, and can provide more reliable product guarantees.

View product certification and testing reports: Priority should be given to selecting products that have passed relevant quality certifications and testing to ensure that their quality and performance meet standard requirements.

Pay attention to installation and maintenance: Proper installation and maintenance are also key to ensuring the performance of insulation strips and leather strips. During the installation process, it should be ensured that the insulation strips and leather straps are tightly attached to the door and window frames; Regularly inspect and replace aging insulation strips and leather strips during use.

In summary, by carefully identifying the material, shape, width, composition, and process, combined with selecting well-known brands and manufacturers, reviewing product certification and testing reports, and paying attention to installation and maintenance suggestions, you can identify the right building materials such as insulation strips and leather strips.
