- **Haljaskatused / Green Roofs**: Pre-cultivated sedum mats and lightweight modular rooftop systems. Certified root-resistant, UV-protective, holding 70% to 90% of annual rainwater runoff. Weight: 45 kg/m2 to 100 kg/m2 fully saturated.
- **Roheseinad / Living Walls**: SemperGreenwall outdoor exterior facades and indoor biophilic living wall systems with automated capillary irrigation and remote web telemetry.
