I write a lot of letters to suppliers around the world. Right now European technology is cutting edge when it it comes to insulation and resource efficiency. REHAU makes the ECOAIR, a large diameter ventilation system that uses the cooling properties of the earth to either pre-cool summertime air, and likewise warm up air in the winter time. Structural insulated panels are so well sealed, a requirement is continuous mechanical ventilation for human health.
“I would like to purchase the REHAU ECOAIR innovative ground-air heat exchanger. Who is my local distributor in Los Angeles CA area? I am developing a super insulation residential project that could utilize the ECOAIR system. If the system is available, please e-mail ordering and pricing information. Thank you.”
