Eternia Windows, the aluminium windows and doors brand backed by Hindalco Industries, is reporting growth in the National Capital Region and Mumbai, driven by increasing demand for premium home improvement products. The development is notable because it highlights how building materials and home infrastructure brands are increasingly moving beyond functional positioning towards consumer-led branding.
Traditionally, categories such as windows, doors and construction materials have relied heavily on dealer networks and contractor influence. Today, urban homeowners are becoming active decision-makers, creating new opportunities for brand-building and premiumisation. The Strategic Read For marketers, Eternia's expansion is another indicator of a broader shift in consumer behaviour. As residential real estate moves up the value chain, consumers are paying greater attention to design, durability, energy efficiency and aesthetics—attributes that lend themselves to branding and storytelling. This creates a growing advertising opportunity in categories once considered low-engagement. Building materials, home improvement products and infrastructure-linked brands are investing more in digital marketing, experience centres, influencer collaborations and regional outreach to reach affluent homeowners directly. For agencies, the implication is clear: premiumisation is extending beyond traditional consumer goods into high-consideration categories. As competition intensifies, differentiation will depend less on product specifications and more on brand perception and customer experience. Our insight The most interesting shift is not that consumers are buying premium windows. It is that they are increasingly buying them as branded products—a change that could reshape marketing investments across India's entire home improvement ecosystem.
