Water-based wood finishes eliminate these hazards, utilizing advanced technology to provide durable protection and rich wood tones with a fraction of the environmental impact. They dry quickly, emit little odor, and are easy to clean up, supporting healthier job sites and living environments. Their clear or tinted formulations preserve the natural beauty of wood in flooring, cabinetry, and furniture, delivering sustainability without trade-offs in quality.

Phase-Change Materials

Phase-change materials (PCMs) are innovative substances that absorb and release heat energy as they shift between solid and liquid states. Integrated into wall panels, ceilings, or furnishings, PCMs help stabilize indoor temperatures, reducing the need for mechanical heating and cooling. This passive energy management contributes significantly to energy savings and lower emissions. Their invisible design integration means comfort and efficiency are improved without altering the visual character of the space, marking them as a discreet yet powerful tool for sustainable interiors.

Electrochromic Glass

Electrochromic glass, often called smart glass, changes its transparency in response to electrical signals.
