Looking to optimize your home’s indoor air quality while maintaining structural integrity? The WhisperComfort Exterior Wall Cap is a tailored solution designed specifically for your WhisperComfort Energy Recovery Ventilator (ERV), ensuring seamless exhaust and supply of fresh air through a building envelope opening.
Unlike generic wall caps that restrict airflow or fail to balance ventilation needs, this accessory is engineered to let both exhaust (stale indoor air) and supply (fresh outdoor air) pass through the hole in your home’s exterior wall—critical for keeping your ERV system operating efficiently. With a precise 4-inch (102mm) diameter, it fits standard building envelope penetrations without requiring custom modifications, making installation straightforward and cost-effective.
What sets this cap apart? Its exclusive design prioritizes your ERV’s performance: by maintaining consistent airflow, it helps reduce energy waste and keeps your home comfortable year-round. Whether you’re upgrading an existing system or installing a new ERV, this cap ensures your ventilation setup works as intended—without compromising durability or weather resistance (thanks to its robust exterior finish).
Spend less time worrying about airflow restrictions and more time enjoying cleaner air and a more efficient home. The WhisperComfort Exterior Wall Cap isn’t just an accessory; it’s a partner for your ERV’s success.
