Self-insulating blocks are building blocks or units that are designed to provide both structural support and thermal insulation in construction projects. These blocks are typically made from materials with excellent insulating properties, such as foam or aerated concrete, and are used to create exterior walls, interior partitions, and other structural elements of a building.

The main purpose of self-insulating blocks is to enhance the energy efficiency of a structure by minimizing heat transfer through walls and reducing the need for additional insulation materials. These blocks often have a high R-value, which is a measure of their thermal resistance. A higher R-value indicates better insulation performance.

Self-insulating blocks come in various shapes and sizes, allowing for flexibility in design and construction. They can be used in residential, commercial, and industrial buildings, providing benefits such as improved indoor comfort, reduced energy consumption for heating and cooling, and lower utility bills.

Features of self-insulating blocks

1. Excellent thermal insulation performance.

2. Heavy and self-light, high strength: density ≤ 600-gk008/m³, compressive strength up to 11.3Mpa.

3. Low rate of water absorption and low shrinkage: the rate of water content is 2.1%, the rate of water absorption is 7.8%, and the dry shrinkage rate is 0.2mm/m, which can avoid hollowing and cracking of the wall , water seepage and other common quality problems of block walls.

4. Good freeze-thaw resistance: after 25 freeze-thaw cycles, the mass loss is 2.1%, and the strength loss is 10%, which is better than common aerated concrete blocks and light aggregate soil Concrete insulation blocks.

5. Excellent fire resistance performance: the exterior is made of high-performance dense concrete, and the interior is filled with inorganic foam concrete and flame-retardant foam boards. It has excellent fire resistance and no fire hazards.

6. The construction process is simple, easy to popularize and apply: no need to do auxiliary heat preservation treatment, the construction process is simple, easy to popularize and apply.

7. Reduced project cost: The external wall project does not need to do other heat preservation treatment, which reduces the process and reduces the project cost.

It's important to note that while self-insulating blocks can contribute to the overall energy efficiency of a building, they are typically part of a larger insulation strategy that includes insulation materials for roofs, floors, and windows, as well as proper sealing and ventilation techniques to ensure optimal thermal performance.
