What Is Thermal Insulation?
Thermal insulation is the process of limiting heat losses and gains in buildings and installations. Technically, it is applied to reduce heat transfer between two environments at different temperatures.
1Thermal Conductivity (W/mK)
The amount of heat passing through a material for a 1 m² surface and a temperature difference of 1°C.
2Thermal Transmittance (W/m²K)
The heat transfer through a material of a given thickness due to the temperature difference between its two surfaces.
3Thermal Resistance (m²K/W)
The arithmetic reciprocal of thermal transmittance and is represented by R.
4Relative Humidity
The ratio of the actual amount of water vapour in air to the maximum amount the air can contain at the same temperature.
5Condensation
The conversion of water vapour into liquid as temperature falls. Internal surface temperature should remain above the dew point.
6Water Vapour Diffusion Resistance Factor
The ratio of a building material’s resistance to water vapour diffusion to that of air.
7Density (kg/m³)
An appropriate density should be selected for dimensional stability and mechanical strength.
8Reaction to Fire
DIN 4102, BS 476 and TS EN 13501 standards are used.
9Temperature Resistance
The product should be selected according to the temperature to which it will be exposed.
10Mechanical Strength (kPa)
Generally expressed as the compressive stress causing 10% deformation in the material.
11Water Absorption
For thermal insulation materials, zero or near-zero water absorption is ideal.
12Dimensional Stability
Dimensional change under temperature or pressure should be very low.
