Market Definition
According to the Climate Technology Centre and Network (CTCN), building thermal insulation is an important technology that reduces energy consumption in buildings by preventing heat gain or loss. It is used to reduce the amount of power required to heat or cool homes and to minimize heat loss in winter and hot-air penetration in summer. Building insulation tends to be the most cost-effective measure in climates with wide temperature ranges. The impact of additional insulation is significant in buildings with thin walls or timber construction. The insulation’s resistance to heat flow is measured or rated by its thermal resistance, or R-value. The higher the R-value, the greater the heat resistance and the less the heat flow.
