High Raw Material Costs and Price Volatility May Hinder Market Expansion Globally

The price volatility of raw materials like fiberglass, mineral wool, polyurethane, and polystyrene, which directly affects the cost of producing insulating goods, is a significant market constraint. Price volatility for chemicals, oil, and gas can make insulation solutions costly, especially for high-performance materials. Adoption is also hampered by the fact that small-scale contractors and manufacturers in developing nations frequently find it difficult to tolerate these pricing swings.
