What is the K value? The K value of the thermal insulation cotton we usually talk about is actually the thermal conductivity of the material, also called the thermal conductivity.
Take two parallel planes with a distance of 1 meter and an area of 1 square meter in the object perpendicular to the heat conduction direction. If the temperature difference between two planes is 1K, the heat conducted from one plane to the other in 1 second is defined as the thermal conductivity of the material, in watt·m-1·K-1 (W·m- 1· K-1).
Generally, materials with low thermal conductivity are called thermal insulation materials (my country's national standards stipulate that materials with thermal conductivity not greater than 0.12W/(m·K) at an average temperature of 350°C are called thermal insulation materials). Materials with a coefficient lower than 0.05 W/m degrees Celsius are called high-efficiency insulating materials. The thermal conductivity of different substances is different; the thermal conductivity of the same substance is related to its structure, density, humidity, temperature, pressure and other factors. The same substance has low water content and low temperature, the thermal conductivity is small. Generally speaking, the thermal conductivity of solid is larger than that of liquid, and liquid is larger than gas. The relationship between K value and R value. The K value/thermal conductivity is defined as the sum of the unit section and length of the material under a unit temperature difference. The heat directly conducted per unit of time.
The R value refers to the thermal resistance of a material. At a certain temperature, a certain material has the ability to prevent heat from passing through a unit area.

【Building fire protection standards】：

At present, there are mainly 5 grades of fireproof materials:
Class A: Non-combustible building materials, materials that hardly burn.
Class A1: non-combustible, no open flame
Class A2: Non-combustible, smoke must be measured to pass.
Class B1: Flame-retardant building materials: Flame-retardant materials have good flame-retardant effects. It is not easy to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly. Remove the fire source and stop burning immediately.
Class B2: Flammable building materials: Flammable materials have a certain flame retardant effect. When exposed to an open flame or high temperature in the air, it will catch fire immediately, which will easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.
Class B3: Flammable building materials, without any flame retardant effect, extremely flammable, and have great fire hazards.
In addition, according to different standards, the classification of fireproof materials is also different:
DIN4102: A1, A2, B1, B2, B3
EN13501-1: A1, A2, B, C, D, E, F
