Judging the quality of a door or window is not only reflected in advanced research and design, but also in the specific details and materials of the door or window. A good door and window not only has a high level of research and design, but also has fine and exquisite workmanship, pays attention to details, has good quality, and a high rate of high-quality products. However, doors and windows with average quality often have many deficiencies in craftsmanship, materials, and detailed operations, resulting in many defects and flaws in the product. Today, the Rising editor will start with rubber strips and take a look at the difference between good doors and windows and ordinary doors and windows. 

The sealing strip of doors and windows is one of the important factors affecting the quality of doors and windows. The sealing strip of Rising doors and windows plays an important role in waterproofing, sealing, and energy saving. It has functions such as sound insulation, dust prevention, antifreeze, and warmth preservation. At the same time, it also has strong tensile strength, good elasticity, and requires good temperature resistance and aging resistance.

According to statistics, the energy consumption of buildings in China accounts for 27.5% of the total terminal energy consumption in society. The energy lost through the gaps around poorly sealed doors and windows usually accounts for about 37-40% of the building's energy consumption. Therefore, it is very important to improve the sealing performance between the fan frame and the glass, especially between the window frame and the window sash.

1、 Modified PVC rubber strip

Modified PVC rubber strip: The price is relatively low, but due to varying quality, low-end products use waste materials, substitute plasticizers, and high filling amounts, resulting in poor elasticity of the rubber strip, easy hardening, pungent odor, easy migration, yellowing of the frame material, and short service life. Due to the presence of halogens and heavy metals in stabilizers in PVC products, they are not conducive to environmental protection. Therefore, developed countries abroad, Beijing and coastal cities in China have eliminated or restricted the use of PVC rubber strips.

2、 Rising EPDM sealing strip

Rising EPDM rubber sealing strip: The main raw materials used for the Rising EPDM rubber strips produced by our company are of the highest quality in the world. The EPDM rubber produced by DuPont in the United States has strong weather resistance and durability. Our company provides a 20-year product quality assurance certificate, allowing you to use it without any worries.

Product Features:

1. Light bulk density, high tensile strength, and non absorbent (replacing traditional materials such as three oil four felt and asphalt wood spruce board). The product is environmentally friendly, easy to construct, and has excellent anti-seepage, leak proof, and waterproofing effects.

2. Corrosion resistance, aging resistance, high and low temperature resistance from 160 ℃ to -45 ℃ without flowing, deformation, brittleness, and long service life.

3. Featuring a separate perforated bubble structure, the specially designed joint board has a honeycomb shaped appearance with evenly distributed holes. It can be tightly bonded and integrated with cement/sealant without the need for roughening, adapting to natural expansion and contraction changes and enhancing the sealing and sealing effect of the joint.

In the actual production process of doors and windows, the proportion of input for sealing strips is very small. However, waterproofing, sealing, energy saving, sound insulation, dust prevention, antifreeze, warmth retention, temperature resistance, aging resistance, these functions cannot be ignored in daily life. So how to distinguish it?

① You can smell it with your nose to see if there is any odor. Normally, there is a slight smell of ethanol, but it is almost imperceptible.

② Wrap the sealing strip tightly around the profile and leave it at high temperature for a period of time (on the roof or in a sunny place). Check if there is any dirt or discoloration on the contact surface between the profile and the sealing strip, if the dust on the surface of the sealing strip turns yellow (oil easily absorbs soil), if there is oil leakage, and if it gets dirty on the hands.

③ Some cheaper sealing strip fillers may have a lot, so the surface will not be very shiny. Those that are cheap and have a dull appearance are not advisable.

④ Look at the proportion. Add a sealing strip with heavy calcium and stretch it back and forth several times by hand. A small amount of white powder will appear on its surface. Even those with poor quality can easily break with just one pull.
