Engineered in Germany, the Schweigen EnviroShield™ is an energy-efficient system that optimizes your home’s ventilation while minimizing heat loss and energy costs. When your rangehood or exhaust fan is switched off, the EnviroShield™ automatically seals shut - preventing cold or hot outside air from entering.
This intelligent magnetic closure creates a dependable, airtight barrier that preserves your home’s thermal envelope, maintaining a stable indoor temperature all year round. With insulation rated at just 2.2 watts per square meter and blower door certification, it delivers outstanding energy savings and airtight performance even under high pressure.
By keeping your indoor air where it belongs, the Schweigen EnviroShield™ enhances comfort, sustainability, and energy efficiency - helping your home stay warmer in winter, cooler in summer, and more efficient every day.
