Problem

Millions of existing homes require significant thermal upgrades to meet modern energy efficiency standards, but traditional retrofit methods are often labor-intensive, disruptive, and yield inconsistent performance. This leads to prolonged project timelines, increased costs, and suboptimal energy savings for homeowners.

Solution

VundaHaus offers a proprietary external wall insulation (EWI) system designed for rapid, high-performance retrofitting of residential buildings. Leveraging precision 3D scanning and factory-fabricated panels, the system ensures a precise fit and significantly reduces on-site installation time. The dry-fit, rainscreen construction provides robust weatherproofing and breathability, contributing to long-term building health and occupant comfort. VundaHaus also provides expert retrofit advice and integrates solutions for fully electrified homes, including heat pumps, solar PV, and battery storage, through a digital-first approach.

Target Audience

The primary customers are homeowners seeking to improve their property's energy efficiency and value through advanced insulation and integrated electrification solutions, as well as property developers and retrofit specialists.
