Hampton (NH), September 2025: Zehnder Group North America (ZGNA) is pleased to announce the signing of a Memorandum of Understanding (MOU) with Small Planet Supply (SPS) and Hayward Lumber, strengthening our shared commitment to promoting healthy indoor environments and accelerating growth across California.

This strategic collaboration brings together Zehnder’s engineering excellence and Lifebreath’s trusted ventilation solutions, alongside Hayward’s strong market presence and SPS’s distribution expertise. By combining these strengths, the partners aim to expand access to premium Indoor Air Quality (IAQ) solutions for builders, homeowners, and commercial customers throughout California.

“We are excited to renew our partnership with SPS and Hayward Lumber,” said Valentina Videva Dufresne, President of Zehnder Group North America. “This agreement reflects our shared values and commitment to creating healthy living spaces. By combining Zehnder’s high-performance ventilation systems and Lifebreath’s installer-friendly solutions with Hayward’s leadership in healthy homes and SPS’s market reach, we are well-positioned to deliver energy-efficient, sustainable solutions that meet the evolving needs of North American customers.”

Maushum Basu, Managing Director of the North America Ventilation Business Unit, added: “California is a critical growth market for us. This partnership enables us to accelerate our regional growth, strengthen relationships with builders, and provide superior technical support and education to the industry.”

Bill Hayward, Executive Chairman & Chief Sustainability Officer, Hayward Lumber, commented, “We’re thrilled to announce this agreement, which enables us to cross-sell industry-leading IAQ solutions to our customers who rely on Hayward for healthy, high-performance building products. Zehnder’s balanced, filtered ventilation delivers steady, clean, fresh air with heat recovery—so you can ventilate without incurring significant energy penalties, even during wildfire smoke. Paired with a tight envelope using a self-adhered, vapor-permeable water-resistive air barrier, it seals air and water leaks to boost comfort and efficiency while protecting the structure from moisture and noise.”

Zehnder and Lifebreath deliver premium IAQ solutions tailored to meet North American standards, offering energy-efficient, ultra-quiet systems for high-performance homes as well as reliable, easy-to-install ventilation for residential and light commercial applications. This partnership reinforces Zehnder’s mission to create healthy indoor climate through innovation, customer focus, and commitment to sustainability.
