Washington RetroFoam LLC

Washington RetroFoam (WRF) is an innovative energy-efficiency and building-performance company focused on upgrading existing residential homes and commercial buildings through advanced insulation technology. By deploying high-performance retro-foam insulation, WRF strengthens building envelopes, significantly reducing energy loss, lowering energy consumption, and improving occupant comfort—without the disruption typically associated with traditional retrofit methods. WRF approaches energy efficiency as both a technology and systems challenge. The company applies data-driven assessments, standardized installation methodologies, and scalable operating processes to deliver consistent, measurable performance outcomes across diverse building types. This technology-forward model enables WRF to address one of the largest and most under-optimized sources of energy waste: aging building stock that predates modern energy codes. By combining materials science with modern operational technology, Washington RetroFoam provides a practical pathway to cost-effective energy efficiency and decarbonization, supporting utility efficiency programs, regional climate objectives, and continued cleantech innovation in the built environment.
