Product Description
Foamed concrete in roof
Advantages of thermal insulation:
1. Thermal conductivity: 0.07 W/m.k, it is 20-30 times better than normal cement products;
2. Light weight: because of its low density, 250-600kg/m3, it is good for reducing building load.
3. Soundproof: foam concrete is constructed by numerous evenly distributed independent closed-cells; therefore, its noise reduction noise ability is 0.09-0.19%. It is 5 times better than its counterpart, normal cement products. It is a solution for noise irritation.
4. Earthquake resistance:
5. Heat resistance ability reach to 250-300 degrees high, polystyrene board softens at 75 degrees.
6. Enhance flooring insulation's stability and lifetime
7. Foam concrete enhances flooring insulation's stability and lifetime through its compression strength and its chemical make up. Its lifetime is 5-10 times longer than polystyrene
8. Environmental friendly product: foam concrete is composed of plant protein and fiber, hence it is neither toxic nor; however, polystyrene and some other chemical materials release some types of harmful gas.

4
Flammability
Easy ignition, releases toxic gas when burns
Neither ignitable, nor not deformable
5
Carrying Capacity
Low; possible cracking occurs when carrying heaving furniture
Carrying capacity:1.2Mpa, eliminate cracking possibilities when carrying heavy loads
6
Duration
6 years of lifetime, usually deform after 1 year, aging easily, especially meet 60ºC or higher.
50 years lifetime, same as filler course; remain the same shape at high temperature
7
Environmental Protection
stink,harmful volatile causes chemical pollution
Tasteless, volatile free,
8
Filler Course Cracker
Crackable even at construction, and tiles are prone to raise when finished
Automated construction, compatible with filler course, and reduce cracking possibility
9
Noise
Reduction
Because of its low density,
Good noise prevention overall, noise absorption 0.09-0.19%
10
Filler course
Filler course needs to be thickened up to 40mm because of its easiness of deformation.
Filler course and noise prevention course are combined together, so filler course is only 30-40 mm (thickness
11
Troweling course
troweling is a must before polystyrene can be used
Not needed at all, because it is part of its properties.
12
Construction Procedure
Complicated procedure. Because U-shaped nail always slip out easily, therefore, PE aluminum coated film and wire mesh are always needed.
Simple construction procedure, firmness of pipes are required, automated construction
13
Construction Speed
An hour is needed to finish 100m²
5 minutes only needed for 100 m² by casting of foam concrete.
14
Economic
No equipment need to be invested, however, construction and materials are relatively higher.
Although the equipment is more expensive, it simplifies construction process. Some associate materials are inexpensive.
15
Quality
Insulating course is layered a few different material; no quality proof.
Both insulation and filler course and made of cement, therefore, they have same lifetime and high quality.
