Advantages of foam concrete roof insulation

2019-07-09 18:55:15

Foamed concrete, also known as foamed concrete and foamed cement, has been developed in domestic and foreign markets for many years, and its technology and market are quite mature. As a building energy-saving material, foamed concrete is widely used in: roof insulation, floor heating engineering, indoor and outdoor cushions, indoor and outdoor insulation, non-load-bearing walls, new energy-saving bricks, earthquake resistance, sound insulation and other construction projects, resulting in huge economic and social benefits.


fine and even foam concrete


Foamed concrete made by foam concrete machine is used in roof insulation for a relatively long time. It has many technical advantages compared to other insulation materials:


foam concrete machine for roof insulation


1. The thermal performance is stable.

The foamed concrete for roofing is mostly 100% cement as dry material, which is a one-component product with stable thermal performance. The thermal conductivity of foam concrete is 0.06 to 0.16 w/m, and the thermal resistance is large. The thermal conductivity of the product can be controlled according to the design, and the ratio can be adjusted after calculation. The control process is easy and the performance is stable, can be poured in large areas.

2. High strength.

Foamed concrete is a high-strength insulation material with compressive strength of 0.25~1.50Mpa and finished product weight of 320~1200kg/m3. According to engineering requirements, the strength and bulk density can be controlled by changing the ratio of raw materials, and the process is easy to control. The roofing insulation material made of foamed concrete, especially the roofing insulation material of the upper body, has its unique advantages, completely solving the shortcomings of the previous insulation materials with insufficient strength and short service life.

3. The water absorption rate is small.

Foamed concrete contains a large number of independent bubbles, and the distribution is uniform, and the overall water permeability of the material is small.

4. Construction work is not difficult.

Foamed concrete on-site operation, 4 people per machine, 40-800m3 per day, no need to occupy other supporting equipment, construction speed is fast.

5. Construction fluidity is good.

Foamed concrete has unique liquid and strong foaming, strong fluidity, long-distance pumping, high working injection capacity, high mechanization, hose pumping and direct pouring.

6. Long service life.

The high-quality foamed concrete has good integrity and is closely combined with the main project. It does not need to leave the gap and the vent pipe, and has a low modulus of elasticity, which is not easy to cause empty drum cracking. The service life is 50 years, which is basically the same as the life of the main body.

We also have foam agent, foam concrete block moulds, foam concrete unit for your choice, if you need more info, please feel free to contact us.
