the sealing strip of doors and windows is one of the important factors affecting the quality of doors and windows. It plays an important role in waterproof, sealing and energy saving. The strip itself also has strong tensile strength, good elasticity, temperature resistance and aging resistance. Now there are so many sealant products in the door and window market, how can we identify good quality? Not afraid, Theo doors and windows teaches several unique skills, so that you can easily distinguish the quality of door and window sealant strips

tensile force measurement

relatively speaking, as a sealant strip material, it should have a certain tensile strength. The standard requirements: strength ≥ 5MPa. The higher the rubber content of the same material, the better the tension. Generally speaking, the service life will be relatively longer and the sealing effect will be better

high temperature detection

wrap the sealing strip tightly on the profile as much as possible, and place it under high temperature for a period of time (on the roof or in a sunny place). Check whether the contact surface between the profile surface and the sealing strip is stained and discolored, whether the dust on the surface of the sealing strip is yellow (it is easy to absorb soil with oil), whether there is oil seepage, and whether it is dirty

observe the color

there will be a lot of cheaper sealing strip fillers, so the surface will not be very bright, and those that are very cheap and do not have a bright appearance are not desirable
