Radon Gas Barriers: The ccSPF Advantage

A naturally occurring radioactive gas, radon is a silent danger to our health. Colorless and odorless, it enters homes and structures through openings in the foundation and below-grade walls, becoming trapped in basements and other poorly ventilated areas. This course looks at methods of controlling radon, how it is addressed in building codes, the advantages of closed-cell spray polyurethane foam (ccSPF) over other insulation materials, and proper installation techniques.

Heat Recovery Ventilation: Why Efficiency Matters

In the last couple of decades, houses have become progressively more airtight due to energy efficiency and cost concerns. While air infiltration and exfiltration rates have been significantly reduced, the need for an efficient ventilation system has become extremely important. This course evaluates different types of mechanical ventilation systems and discusses why heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems are characterized by a high level of energy efficiency and as an effective means for improving indoor air quality.
