1. Water Absorption Rate: Insulation for buildings is akin to wearing a cotton coat on a structure. This coat must not only provide external insulation but also should not absorb water.
2. Breathability: The breathability technical indicator refers to the diffusion resistance of water vapor. If the exterior wall insulation system has poor permeability, the diffusion of water is blocked, leading to: 1. Blocking the exit of moisture from the wall, affecting the color of the surface paint; 2. Causing stress that leads to blistering and peeling of the paint film; 3. Gradually increasing the moisture content of the wall, leading to condensation water accumulation, which adversely affects the wall's performance, such as thermal and structural aspects; 4. Even if the exterior wall insulation system meets energy-saving standards, it can cause indoor air to become polluted, making it unsuitable for habitation.
3. Bond Strength: Reflects the adhesion firmness of the wall insulation material, to reduce and avoid hollow bulges, cracks, and peeling in the wall insulation system, ensuring the safety and durability of its functional use.
4. Tensile Strength: Insulating boards reach a certain tensile or tear strength.

Many people use thermal conductivity as the sole criterion when choosing thermal insulation materials, either as external insulation or based on low water absorption and thermal conductivity. However, thermal conductivity is a common indicator for assessing insulation performance and a crucial reference for selecting insulation materials. The quality of thermal insulation materials, though, is not solely determined by this one factor; a comprehensive judgment should refer to the following indicators:

Some consumers inquire about when prices are cheaper, with the intention of stockpiling and purchasing products in advance for next year. They plan to continue using them once the weather warms up and construction can proceed normally. This way, they can save a great deal, as manufacturers tend to offer promotions during the winter when prices are lower. At that time, the price per cubic meter of rock wool boards is particularly attractive to consumers.
When is the price per square meter of rock wool board cheaper?
Rockwool composite board1. Superior performance: The exterior rock wool composite panels are made of A-grade non-combustible materials.Rockwool boardInsulation or energy-saving retrofitting for exterior walls of new or existing buildings with dense structures like concrete or brick walls. It boasts an A1 fire rating, offering fireproofing, noise absorption, and reduction, along with high compressive and tensile strength, low water and moisture absorption, good dimensional stability, and resistance to aging. It is well-compatible with the exterior wall system, has a lifespan similar to the building structure, and provides multiple functions such as thermal insulation, energy saving, fire protection, and climate protection for the building.。

Winter rock wool board prices are more affordable due to increased inventory levels during the winter, which is also its off-season. Purchasing it at this time allows you to get excellent insulation material at a great price. Many people ask when is the best season to buy rock wool boards at a lower price. Before answering this question, we should first consider when its off-season occurs.
The answer is undoubtedly winter, as the drop in temperatures leads to many construction sites being unable to operate, thus reducing the demand for mineral wool insulation materials. This is when manufacturers, facing an excess in supply, naturally lower the price per square meter of mineral wool boards.
Rock wool composite panels may shed a layer of dust on the surface after some time, affecting the decorative effect of the wall.To maintain wall cleanliness, regular cleaning is recommended.
Clean with detergent powder, especially for certain tape marks. It works great. Method: First, wipe the walls with a damp cloth. After drying, check for any noticeable stains. Dampen the cloth with some degreaser powder and wipe back and forth on the spot. It's very effective.
