|---|---|
| Residential Buildings | 52.6% |
Given the demand for thermal efficiency, soundproofing, and cost savings on energy in homes and apartments, the largest application segment in the HVAC insulation market is residential buildings. HVAC insulation is important because it helps hold temperatures inside the home and works to decrease the load on an HVAC system and increase the comfort of a dwelling in all seasons.
High-performance insulation is also becoming a more integral part of new housing developments to meet more stringent energy codes such as energy star, LEED, and BREEAM certifications. Simultaneously, HVAC upgrades and retrofits of aging residential buildings lead to duct insulation being a priority for energy efficiency measures.
Growing consumer awareness about indoor air quality and savings on utility bills is also driving the adoption of insulation materials that minimize temperature variation and condensation on duct surfaces. Glass wool insulation in particular is often the packager choice with residential retrofitting due to safety, longevity, and ease of handling. Residential buildings, a large segment of the overall market, drive HVAC insulation demand from unit volume alone, efficiency requirements mandated by policy, and the growing emphasis on home sustainability and comfort by consumers.
Increasing energy efficiency codes and more stringent building sustainability requirements are driving the growth of the heating, ventilation and air conditioning (HVAC) insulation market. HVAC insulation improves the thermal effectiveness, reduces energy consumption, and controls condensation and audible noise in heating, ventilation, and air-conditioning systems.
Increasing investments in green buildings, fast-paced urbanization and retrofitting of old infrastructure are expected to propel demand in residential, commercial and industrial sectors. Other floor manufacturers are also working on new insulating materials such as elastomeric foams, fiberglass, and phenolic foams with low thickness, low thermal conductivity, and fire resistance properties and higher LEED and ISO compliance.
