Moreover, the door leaf is designed with a layer of honeycomb paper for effective sound insulation and thermal insulation.

The door leaf is equipped with premium door bolts, ensuring smooth and quiet opening and closing. For added convenience and home safety, accessories such as frosted glass and peepholes can be installed. Additionally, to prevent strong impacts or the risk of finger or toe injuries, intelligent door stoppers can be used.

1.3. Door Frame

The structure of the door frame is made from composite material, with two main mold types: single mold (42*120mm) and double mold (depending on the desired size and pre-order). The door frame is constructed using molded strips combined with pressed panels, facilitating flexible assembly and ensuring robust protection.

The door frame is intended for a fixed and secure fit, allowing easy opening and closing without loosening. A composite door frame meeting standards includes:

• Strips fitting snugly with the hinge.
• Rubber gaskets for shock absorption, reducing strong impacts and providing good resistance.
• Frame mold for lifting the entire door leaf, connected to the door leaf by door hinges.
• Sturdy stainless steel hinges for user safety when opening or closing the door.
• A thin PVC film surface for even coloring, excellent scratch resistance, and termite resistance.

1.4. Included Accessories

In addition to the key features, the structure of composite plastic doors includes essential accessories such as:

• • Door lock: Modern lock types, such as smart locks, horizontal handle locks, or round knob locks, can be chosen.
  • Safety bolts: To ensure absolute protection for the house, additional safety bolts can be installed.
  • Door hinges: For each composite door, it is recommended to use 3 to 4 hinges, corresponding to 6-8 hinges for 2 door leaves.
  • Glass windows: Transparent or frosted glass windows can be chosen based on purpose and usage needs.
  • Rubber gaskets: The purpose of using this accessory is to facilitate easy door closing and provide effective sound insulation.
  • Pneumatic door closer: A type of automatic door closing device that gently and smoothly closes the door.
  • Peephole: An essential security accessory for easy observation and avoiding dangerous situations.
  • Draft excluder: This accessory helps with thermal insulation, wind resistance, and prevents situations where fingers or toes get caught in the door.
  • Frame reinforcement: To firmly fix the door leaf, a frame reinforcement can be used in conjunction with the hinge.
  • Door stopper: This accessory helps prevent strong impacts that can cause scratches or damage to the door and the floor.

2. Key Advantages of Composite Plastic Doors

2.1. Detailed Structure of Composite Door Frames

The structure of composite plastic doors is made from a composite of wood powder and PVC, molded at high temperatures. Synthetic wood doors consist of 70% plastic and 30% wood powder, creating a product that closely resembles natural wood. However, the composite structure has the ability to resist water and termites by 100%, preventing warping and shrinking. Moreover, composite doors have a balanced stiffness and weight, providing a comfortable user experience. The plastic particles covering the wood particles help the material withstand the effects of water, possessing the rigidity of wood and the flexibility of plastic.

2.2. Surface of Industrial Composite Wood Doors

Things you should know and consider when using composite doors. Composite wood doors are coated with a premium PVC film. Thanks to this, plastic wood doors have a wood grain layer that simulates natural wood patterns and maintains an even color. The PVC film surface has excellent scratch resistance and chemical resistance. Composite wood doors tested by the General Department of Quality Measurement are not affected by chemicals (NaOH 40%, NaCl 10%, H2SO4 40%, HNO3).

2.3. Moisture Resistance, Soundproofing, Thermal Insulation

Composite plastic wood doors have a consistent structure with a film-coated water-resistant composite wood. The structure of plastic particles wrapping around wood particles prevents moisture from penetrating inside the door. Composite wood doors have been tested by the General Department of Quality Measurement and do not swell when immersed in water for 24 hours. Plastic wood doors are the only door type unaffected by water and humidity. The size of composite plastic doors does not change with moisture and temperature, remaining undistorted. The soundproofing ability of KingDoor Composite Wood Doors is average. The solid casting of the door leaf and frame creates soundproof spaces. Therefore, the soundproofing ability of composite plastic doors is at a moderate level, reducing from 145.2 dB to 104.5 dB according to test results.

2.4. High Load-Bearing Capacity

The structure of plastic wood doors, with plastic particles covering wood particles, provides the product with the stiffness of wood and the flexibility of plastic. The thickness of the door leaf and frame of plastic wood doors is close to that of industrial wood doors and much larger than that of ABS plastic doors. Therefore, the impact resistance (opening, closing, wind) is very good. Specifically:

• The maximum deformation under wind force P from 100 Pa to 500 Pa is between 0.02 and 0.15.
• Tensile strength is 4.75 MPa, bending strength is 13.2 MPa.

2.5. Adaptability to Door Frame Grooves

Industrial wood doors use continuous strips, and door frames are produced according to the wall thickness, leading to time-consuming construction. Composite wood doors use strips with legs that fit directly into the frame. Smart strips with legs only appear in the plastic wood door line, shortening the construction time to the minimum. Composite doors have the ability to adapt to all types of walls.

2.6. Safety, Environmentally Friendly

Composite wood doors are made from wood powder and PVC, used in water pipes. All are absolutely safe for humans and do not use adhesive glue or harmful additives. According to tests by the General Department of Quality Measurement, composite wood doors do not contain formaldehyde. Absolutely safe for the health of users. The materials that make up composite wood doors also contribute to replacing the use of natural wood, ensuring human safety, and are trusted by interior experts.

3. Applications of Composite Doors in Daily Life

With the features we have mentioned above, this door type has high practicality. Composite plastic doors are used for interior doors, living rooms, bedrooms, etc. Depending on different spaces, composite doors always meet the needs of customers. Besides, for those still wondering about the question “Can composite doors be used as main doors?”

We would like to answer that they can. Currently, various models of composite plastic doors are gradually becoming prominent. With the characteristics of being compact, durable, and many other outstanding advantages, they are increasingly chosen to replace traditional doors made of materials such as wood, iron, aluminum, etc. The name “composite plastic doors” has become a “hot” and popular term in the field of decoration and interior design.
