Building Insulation Market Segmentation: By Insulation

• Bulk
• Reflective

Bulk insulation functions by capturing pockets of air within its material, limiting heat flow through conduction and convection. It contains products such as fibreglass batts, mineral wool rolls, and cellulose that are typically applied on walls, ceilings, and floors. Reflective insulation, however, works by reflecting radiant heat, hence suitable for application in hot weather conditions where solar heat gain is a factor. They are generally constructed with aluminium foils, polyethene bubbles, or foam boards and installed in attics and on roofs. Reflective insulation, on the other hand, excels when laid in an air gap. In total, mixing the two has better overall energy efficiency in structures. Insulation types by geographical area are diverse, with cold places preferring bulk insulation and hot regions preferring reflective insulation. With increasing energy regulations, hybrid insulation systems that integrate bulk and reflective properties are becoming popular. High-radiation environments such as industrial facilities and data centres are benefiting from enhanced insulation performance provided by advanced reflective technologies.
