### **5 Critical Factors: Choosing Between Honeycomb & Solid Core Doors (Weight Savings Revealed!)**
The door core dilemma – honeycomb or solid? This decision impacts everything from installation costs to long-term performance. After manufacturing 500,000+ doors worldwide, we reveal eye-opening test data showing how **lightweight** honeycomb doors outperform traditional solid cores in high-rise buildings, while solid core maintains advantages in specific scenarios. Discover which solution truly fits your project through our comparative lab tests and real-world case studies.
#### **1. The Weight Comparison: Aluminum Honeycomb vs Solid Wood Core**
✔ **By the Numbers:**
– Solid wood core (40mm): 48-55kg per door
– Aluminum honeycomb (same size): 18-22kg (63% lighter)
– Steel honeycomb hybrid: 25-30kg
✔ **High-Rise Impact:**
– Reduces structural load by 1.2 tons per 20 floors
– Enables faster installation (3x more doors/day)
*Project Example:*
A Shanghai skyscraper saved $140,000 in elevator reinforcement costs by switching to honeycomb
#### **2. Sound Insulation: Laboratory Test Results**
✔ **STC Ratings at 44mm Thickness:**
| Core Type | Standard | With Acoustic Layer |
|———–|———|———————|
| Solid Wood | STC 32 | STC 35 |
| Aluminum Honeycomb | STC 28 | STC 33 |
| Our Hybrid Honeycomb | STC 31 | STC 37 |
✔ **Real-World Performance:**
Hospital ICU tests showed only 2dB difference between premium honeycomb and solid core
#### **3. Thermal Performance: R-Value Comparison**
✔ **Per 40mm Thickness:**
– Solid wood: R-1.25
– Basic honeycomb: R-1.8
– Insulated honeycomb: R-3.2
✔ **Climate Test Data:**
Maintained 5°C better temperature stability in Dubai summer trials
#### **4. When Solid Core Still Wins**
✔ **Absolute Soundproofing:** Recording studios, private offices
✔ **High-Security Needs:** Better ballistic resistance
✔ **Historic Renovations:** Matching original specifications
#### **5. The High-Rise Advantage of Lightweight Doors**
✔ **Structural Benefits:**
– 40% less stress on door frames
– Allows thinner floor slabs
– Better seismic performance
✔ **Installation Perks:**
– No crane needed for upper floors
– 70% faster installation
– Lower worker injury risk
### **Side-by-Side Comparison**
