The main performance of doors and windows is sealing. Only doors and windows with strong air and water tightness can truly protect the home.

For door and window sealing, in addition to the profile of the door and window itself, the next step is the role of sealing strips and sealant.

If you choose door and window profiles with good thermal insulation performance, the correct use of sealing strips and sealants will determine whether the doors and windows can be denser and less ventilated in the future!

What is the difference between sealing strips and sealants?

A sealing strip is a product that seals something so that it is not easy to open, and plays a role in shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, fixation, etc. Sealing strips are made of rubber, paper, metal, plastic, and various materials.

Sealing glue is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill structural gaps and provide a sealing effect.

Simply put, it means:

The sealing strip of the window is used around the glass, and the sealant is used at the contact position between the window frame and the wall.

So, when installing doors and windows, both sealing strips and sealant are indispensable!

Tips for selecting window sealing strips:

1. Smell with your nose to see if there is any odor. Normal PVC material will have a slight, mellow smell, which 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 specific gravity, how many meters can be produced per kilogram. There are many manufacturers who tamper with the use of fillers. In order to pursue greater production, they use talcum powder, heavy calcium and other materials as fillers (to save some electricity), greatly increasing the proportion of sealing strip products. (Our users usually buy by kilogram and use by length) This invisibly increases the cost, which is not worth the loss. Add a sealing strip with heavy calcium and stretch it back and forth several times by hand, and a small amount of white powder will appear on its surface.

Our company's main product is EPDM sealing strips, and the registered trademark is "Rising" brand. The main function of EPDM door and window sealing strips is to seal and fix doors, windows, and curtain wall glass. The main raw material is EPDM original rubber. The company has always used imported EPDM original rubber produced by world-renowned companies DSM in the Netherlands and DuPont in the United States. The carbon black used is a product from German Guisai Chemical Co., Ltd. Other auxiliary materials are also selected from domestic legitimate companies. We do not seek low prices but only good quality.

The advantages of EPDM rubber strips are stable product performance and good usability. Anti aging and corrosion resistance. The physical indicators such as UV resistance, stretchability, and aging resistance of the product remain basically unchanged under the conditions of -40 ° C to 160 ° C.

Tips for selecting window sealant:

1. Green, environmentally friendly, healthy, and odorless

Choose healthy, non-toxic, odorless, and environmentally friendly sealant.

2. Durable sealing and waterproofing

Choosing sealant has the characteristics of low tension, high compression and weather resistance, strong stability, excellent adhesion, and long-lasting waterproof sealing.

3. Strong stain resistance

Ordinary sealants will become moldy and dirty after a period of use, affecting the appearance of the home. Therefore, it is important to choose sealants that will not experience such problems for a long time!

4. Strong antioxidant properties, efficient anti mold and crack prevention

Sealing glue has efficient antioxidant properties, and high-quality ones can guarantee no cracking or powdering for more than ten years!
