In the cold winter, a Front Door with good insulation performance is crucial for maintaining indoor warmth. Optimizing the insulation performance of the front door can be approached from two aspects: material selection and sealing strip matching.

Material selection

-Solid wood doors: Solid wood doors have good insulation performance due to their natural fiber structure. The porous nature of wood can absorb sound waves and reduce heat loss. However, solid wood doors are relatively expensive and require regular maintenance to maintain their performance.

-Steel doors: Steel doors are usually composed of mesh steel ribs placed between two panels, and the internal filling material is mostly glass wool. Panels are often made of cold-rolled steel plates because their surface is smoother than hot-rolled steel plates. Steel doors have good insulation effect and high strength and durability.

-composite door: composite doors combine the advantages of multiple materials, such as the frame of solid wood composite doors using solid wood materials and filled with various insulation materials inside. This type of door not only has the insulation performance of solid wood doors, but also further enhances the sound insulation effect through composite structures.

Sealing strip matching

-EPDM rubber sealing strip: EPDM rubber is a commonly used sealing material with good elasticity and durability. It can effectively fill the gap between the door and the door frame, reducing heat loss. This type of sealing strip will expand when exposed to water, thereby enhancing its water tightness performance.

-Multi chamber structure sealing strip: The sealing strip of multi chamber structure can provide higher air tightness and water tightness. For example, the middle sealing strip of the frame fan adopts a multi cavity structure, with an inner edge, an outer edge, and a sealing angle. The outer edge and sealing angle are made of dense EPDM rubber, while the inner edge is made of foamed EPDM rubber and has a slope corresponding to the insulation bridge. When the doors and windows are closed, the sealing strip of the frame fan is in contact with the insulation bridge, achieving effective triple sealing.

-Long tail design sealing strip: The glass inner and outer rubber strips both adopt a long tail design. The installation bayonet of the inner glass adhesive strip is embedded into the buckle, and the outer glass adhesive strip is installed on the passive door and window sash profile through the installation tab. The long tail design of the adhesive strip can be lapped onto the polyethylene foam strip. The contact surface between the foam strip and the glass is in the shape of corrugated strip. This design divides the space between the passive door and window frame profiles and the insulated glass into two parts, inside and outside, effectively blocking the radiation and conduction of heat, and improving the overall insulation performance of the doors and windows.

Matlab

-Broken bridge design: Broken bridge aluminum windows effectively cut off heat conduction by adding insulation strips between indoor and outdoor aluminum profiles. Insulation strips are usually made of nylon 66+25% fiberglass material, with a thermal conductivity of only 0.3W/(m · K), which can significantly improve the insulation performance of doors and windows.

-Multi channel sealing: Adopting a multi channel sealing design can further improve the air tightness and insulation of doors and windows. For example, optimizing the profile structure, adjusting the design of the hardware functional slot from the outer side of the transfer material chamber to the inner side, cutting off the metal "thermal bridge" at the handle, and replacing the exposed hinges with hidden hinges can effectively improve the insulation performance.
