The main indicators for evaluating the combustion and fire resistance of thermal insulation products mainly include combustion performance index (flame spread speed and flame extension distance), pyrolysis performance (smoke density and smoke toxicity), and fire point and spontaneous combustion t...
The relationship between the thermal conductivity of the insulation material is λ=k/(ρ×c), where k represents the thermal conductivity of the material, ρ represents the density, and c represents the specific heat.
1. The concept of thermal conductivity
In insulation materials, thermal conductivit...
Definition of thermal conductivity: It is usually represented by the character “λ”, and the unit is: Watt/meter·degree (W/(m·K), where K can be replaced by ℃. Thermal conductivity (also known as thermal conductivity or thermal conductivity) is a measure of the thermal conductivity of ...
Apparent density refers to the ratio of the mass of a material to its apparent volume. Apparent volume is the actual volume plus the closed pore volume. It refers to the ratio of the space occupied by a material under the action of an external force to the mass of the ma...
The choice of insulation thickness is a critical factor in building design and energy conservation. One of the most important factors influencing this decision is the ambient temperature of the building’s location. Understanding the relationship between ambient temperature and insulation th...
When optimizing the efficiency of your HVAC system, one of the most important factors to consider is insulation.
