What is JUSEN Solid Core Panel?
JUSEN Solid Core Panel is a new type of composite door core filling material independently developed by JUSEN DOORS, integrating the brand’s aerospace-grade quality control standards and precision manufacturing technology. Different from traditional door core materials such as bridge-hole mechanical panels and solid wood blocks, JUSEN Solid Core Panel focuses on solving the pain points of poor sound insulation, easy deformation, poor moisture resistance, and insufficient environmental protection of traditional door cores, creating a all-round high-performance door core solution for global high-end wooden door users.
On December 22, 2024, JUSEN DOORS officially launched the new “Ultimate Skin Paint Series” wooden doors, all of which adopt JUSEN Solid Core Panel as the internal filling. At the same time, JUSEN announced that in 2025, the internal filling of all core products of JUSEN DOORS will be fully upgraded to JUSEN Solid Core Panel, which means that every high-end wooden door of JUSEN will be empowered by this high-performance core material, bringing users a better experience of quiet, stable, and environmentally friendly home life.
Core Design: Honeycomb Compartment Structure — The Secret of Multiple Advantages
The honeycomb compartment structure is the core design highlight of JUSEN Solid Core Panel, which is the key to its outstanding performance in all aspects. This structure integrates four core strengths, and each performance index is supported by authoritative test data, fully reflecting JUSEN’s pursuit of precision and quality.
1. Enhanced Sound Insulation & Noise Reduction — Create a Quiet Home Environment
Noise pollution has become one of the main factors affecting home comfort. JUSEN Solid Core Panel solves this problem through its unique honeycomb compartment structure. The independent honeycomb units split the external environmental noise into separate compartments, effectively preventing large-area noise penetration. At the same time, the hollow cavities in the honeycomb can reflect and absorb sound waves, reducing the energy of noise and achieving a better noise reduction effect.
According to the test data from Beijing Building Materials Inspection and Research Institute (a national authoritative testing institution), the 45mm-thick door leaf filled with JUSEN Solid Core Panel has a noise reduction effect 2 decibels higher than that of traditional bridge-hole mechanical panels. This means that it can effectively block the noise from the outside, such as traffic noise and neighborhood noise, as well as the internal noise of the home, creating a quiet and comfortable living space for users. For families that pursue a quiet home environment, JUSEN Solid Core Panel wooden doors are undoubtedly the ideal choice.
2. Optimized Thermal Insulation — Energy-Saving and Comfortable
Thermal insulation performance is an important indicator of high-end wooden doors, which is related to the energy efficiency and comfort of the home environment. The honeycomb structure of JUSEN Solid Core Panel reduces the overall density of the panel, forming a natural “air insulation layer”. The air in the closed honeycomb compartments has poor fluidity, which can significantly reduce the heat transfer efficiency, thereby achieving excellent thermal insulation effect.
Test data shows that the thermal conductivity of JUSEN Solid Core Panel is only 1.5W/(㎡·K), reaching Grade 8 thermal insulation performance. This means that in winter, it can effectively reduce the loss of indoor heat, keeping the room warm; in summer, it can block the entry of external heat, reducing the use frequency of air conditioners and indirectly improving the energy efficiency of the home. For users in different climate regions around the world, JUSEN Solid Core Panel can bring a more comfortable living experience.
3. Balanced Structural Stability & Lightweight — Durable and Easy to Install
Traditional door core materials often have the problem of being either heavy and easy to deform, or light but insufficient in stability. JUSEN Solid Core Panel solves this contradiction through the hexagonal three-dimensional support of the honeycomb units. The hexagonal structure can evenly distribute external forces (such as extrusion, impact) to the entire panel, avoiding local deformation and ensuring the structural stability of the door leaf.
At the same time, the hollow structure of the honeycomb reduces the usage of materials. While ensuring a compressive strength of 0.48MPa (higher than the national standard), it effectively reduces the overall weight of the door leaf. This not only makes the installation of wooden doors more convenient and labor-saving, but also reduces the load on the door frame, extending the overall service life of the wooden door. Combined with JUSEN’s precision hardware supporting, JUSEN Solid Core Panel wooden doors are more durable and reliable.
4. Auxiliary Moisture Resistance & Environmental Protection — Safe and Healthy
Moisture resistance is a key performance that wooden door core materials must have, especially for users in humid regions. JUSEN Solid Core Panel is mainly composed of inorganic materials, which have excellent moisture resistance. In addition, the closed honeycomb compartments further reduce the path of moisture penetration, and the independent chambers can prevent moisture from diffusing inside the panel. With the low water absorption of the material itself (no expansion or shrinkage), the moisture resistance of the door leaf is greatly enhanced, which can adapt to the living environments in different regions.
In terms of environmental protection, JUSEN Solid Core Panel has obvious advantages. The honeycomb structure requires little adhesive filling, and cooperates with the inorganic materials of the panel (with ultra-low formaldehyde emission) to further ensure environmental safety. After testing by national authoritative institutions, the formaldehyde emission of JUSEN Solid Core Panel is only 0.012mg/m³, which is far lower than the new national ENF level standard (0.025mg/m³), fully meeting the high environmental protection requirements of modern homes and protecting the health of users and their families.
Full Functional Features of JUSEN Solid Core Panel Wooden Doors
Based on the excellent performance of JUSEN Solid Core Panel, JUSEN Solid Core Panel wooden doors have comprehensive functional advantages, covering stability, moisture resistance, flame retardancy, environmental protection and other aspects, meeting the needs of high-end home, commercial and other scenarios.
1. Stability & Moisture Resistance: Adapt to Various Environments
JUSEN Solid Core Panel is mainly composed of inorganic materials bonded with inorganic mineral adhesives (such as silicon and calcium), with a compressive strength of 0.48MPa, which exceeds the national standard and has stronger structural stability. Its low water absorption can effectively prevent the door leaf from expanding or shrinking due to changes in humidity, and can adapt to the living environments in different regions, whether it is the humid south or the dry north, it can maintain the shape and performance of the door leaf without damage.
2. Flame Retardancy & Heat Insulation: Safe and Reliable
In terms of fire resistance, JUSEN Solid Core Panel is mainly made of non-combustible inorganic mineral materials, with a total heat value of only 2.7MJ/kg, a fire growth rate index of 84W/S, and a total heat release within 600 seconds of 1.6MJ — all of which are far below the national standard, achieving Grade A2 combustion performance (a high national fire safety rating). This means that in case of fire, it can effectively delay the spread of fire, reduce the damage caused by fire, and provide more escape time for users.
In terms of thermal insulation, as mentioned earlier, the honeycomb compartment structure ensures that the panel has low density and excellent thermal insulation performance, which not only reduces the exchange of indoor and outdoor temperature, but also improves the fire insulation effect, further enhancing the safety of wooden doors.
3. Safety & Environmental Protection: Healthy and Environmentally Friendly
Formaldehyde emission is an important indicator to measure the environmental protection of wooden doors. JUSEN Solid Core Panel has passed the test of national authoritative institutions, with a formaldehyde emission of 0.012mg/m³, which is far lower than the ENF level standard, realizing true environmental protection and no pollution. At the same time, its smoke toxicity meets the national Standard Safety Level 2 (ZA2), ensuring that the harmful smoke released in case of fire is minimized, further protecting the safety of users.
4. UV Resistance & Long Service Life: Durable and Cost-Effective
The inorganic material composition of JUSEN Solid Core Panel has high chemical bond energy in its molecular structure, which can effectively resist UV radiation. The energy of UV rays cannot easily break its molecular chain, avoiding problems such as fading, chalking, and reduced strength of the door leaf under long-term UV exposure. In addition, the honeycomb structure can also block and reflect part of the UV rays, further reducing the impact of UV rays on the internal materials of the door leaf.
At present, there is no official data on the exact service life of JUSEN Solid Core Panel, but its excellent stability, high compressive strength, moisture resistance, UV resistance and flame retardancy ensure that its performance degrades slowly under normal use. With proper use and maintenance, the service life of JUSEN Solid Core Panel wooden doors is expected to reach more than 10 years, which is more durable than traditional wooden doors and has higher cost performance.
