        The function of the sealing strip, besides being quiet, is also reflected in many other aspects, such as it plays a significant role in the overall thermal insulation and heat insulation of the room, and also has a strong protective effect on the door cover and door leaf.
        Wooden door seals are mainly made of EPDM rubber foamed and densely compounded with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical action, and a wide operating temperature range (-40 ° C to + 120 ° C). , Contains unique metal clamp and tongue buckle, sturdy and durable, easy to install. Wooden door seals play a key role in other doors and windows such as wooden doors, security doors, sliding doors, various aluminum-plastic doors and windows.
        The most obvious is shock resistance. After it is installed, it reduces the impact noise when closing the door, protects the edge of the door leaf, extends the life of the door, and reduces noise. The second is to seal, dampen, and isolate indoor and outdoor air, which effectively plays a role of heat preservation and energy saving, and will prevent small insects such as mosquitoes from getting into the room. Slotted sealing strip is a groove formed on the door frame to install the sealing strip. This slotted sealing makes the sealing strip embedded in the groove difficult to fall off and easy to install.
