Aerfoam Insulated Ducts
by Brink / 475 High Performance Building Supply
Product Overview
The Aerfoam insulated ducting is an easy-to-install solution designed to prevent heat loss and condensation. Insulated ducting is recommended for transporting outside air to Heat Recovery Ventilation (HRV) / Energy Recovery Ventilation (ERV) units and for exhausting air from these units to the outdoors.
Advantages & Properties
- Well-insulated
- Sound-absorbing
- Low pressure drop due to smooth inner surface
- Non-porous
- Airtight
- Doesn't rust
- Compact, mechanical connections (i.e., no tape or sealants required)
- Extremely light material
- Easy and safe to cut
- Pliable
- Impact resistant
- Easy to dismantle for maintenance
