Why 3 Billion Windows? Our 2040 Vision for Global Living Spaces
The Math Behind 3 Billion
According to the 2023 Global Housing Report by UN-Habitat, there are approximately 20 billion windows in residential buildings worldwide. As urbanization accelerates, this number is projected to grow by 1.2% annually.
Our Commitment by 2040
Three Girls Curtains aims to contribute to 15% of global window upgrades by 2040 (equivalent to 3 billion windows), focusing on energy-efficient and youth-centric designs. This is an aspirational target, not a current market position claim.
*Based on linear projections of UN-Habitat data, assuming 2.5% annual growth in retrofit demand.
Transparency Note
This vision represents a voluntary industry contribution goal. Three Girls Curtains does not seek market dominance, and the 15% target is unrelated to any competitor's market share.
