This article will combine the search popularity data of the past 10 days to systematically analyze the most effective terrace capping and insulation solutions for you and provide structured comparative data.
1. Search ranking of recent popular thermal insulation solutions
| Plan type | Search popularity index | Cost range (yuan/㎡) |
|---|---|---|
| Sun panel ceiling | 98,000 | 120-300 |
| Aluminum foil insulation film | 72,000 | 25-80 |
| green roof | 65,000 | 200-500 |
| Glass roof + sunshade | 59,000 | 350-800 |
| foam concrete | 43,000 | 180-400 |
2. Technical comparison of mainstream thermal insulation solutions
| Plan | Thermal insulation principle | cooling effect | Service life |
|---|---|---|---|
| Sunshine board | Hollow layer heat resistance | Lower 5-8℃ | 8-12 years |
| Aluminum foil film | Reflect UV | Reduce 3-5℃ | 3-5 years |
| green roof | plant transpiration | Reduce 8-12℃ | More than 15 years |
| shading system | Physical shading | Reduce 6-10℃ | 5-8 years |
| Thermal insulation coating | heat reflective technology | Reduce 4-7℃ | 5-7 years |
3. Recommendation of cost-effective combination solutions
According to recent popular discussions on decoration forums, the following two combination solutions have received the highest praise rates:
1.Sun panel + aluminum foil film double-layer structure: First install the hollow solar panel frame, and then paste the aluminum foil reflective film on the inside. The comprehensive heat insulation effect is increased by 40%, and the cost is controlled at 200-350 yuan/㎡.
2.Light greening + automatic sprinkler system: Use Crassulaceae succulent plants as the green layer, and use intelligent humidity sensor sprinkler irrigation to ensure heat insulation and facilitate maintenance. The initial investment is about 380 yuan/㎡.
4. Construction precautions
1. Waterproof treatment: No matter which solution is adopted, the base layer must be waterproofed. It is recommended to use polyurethane waterproof coating + waterproof membrane for dual protection.
2. Load-bearing assessment: The green roof must ensure that the floor load-bearing is ≥150kg/㎡, and the wind pressure load must be calculated for the solar panel structure.
3. Ventilation design: A closed ceiling must reserve no less than 5% ventilation area to prevent the accumulation of hot air.
5. Trends in new thermal insulation materials in 2023
| Material name | Features | average market price |
|---|---|---|
| airgel insulation board | Thermal conductivity 0.018W/(m·K) | 280 yuan/㎡ |
| Phase change temperature regulating material | Automatically regulates temperature fluctuations | 420 yuan/㎡ |
| Nano reflective coating | Reflectivity ≥92% | 65 yuan/kg |
From the above analysis, it can be seen that terrace insulation needs to be comprehensively selected based on budget, load-bearing conditions and maintenance costs. Recent search data shows,Sun panel and green roof combination planAttention increased by 23% month-on-month, becoming the most popular insulation renovation plan this summer.
