Insulation Options for Homes - Fiberglass
Without question, the most popular material used for insulating buildings is fiberglass, which comes in many forms, including rigid boards, batts, and blown/loose-fill product.
Fiberglass insulation has the distinction of not only being one of the most popular and recognizable building insulation materials, it is often the most affordable and includes significant environmental benefits as one of the largest users of recycled glass in the world.
Recognizing some of the unique challenges and perceptions of fiberglass batt insulation with respect to grade one installation, the fiberglass insulation industry is taking great care to provide training, education, and extra oversight for installation contractors to achieve high levels of quality.
In this class, you will learn what step are being taken to achieve these higher levels of quality and more, as we continue our exploration of the three most popular insulation products (cellulose, fiberglass and foam).
What we'll be covering:
- The history of fiberglass insulation as a building product and in other industries
- How fiberglass insulation is manufactured
- The environmental benefits of fiberglass insulation
- Batts vs. Blown/Loose-fill insulation
- Efforts underway to ensure grade one installation levels of quality
- Review some of the newest products being offered by the industry

Heat Pump Water Heaters
Heat pumps have grown in popularity over the past 50 years, but most people are not aware that the technology is almost 170 years old, invented by Austrian engineer Peter von Rittinger in the 1850's.
While most people think of heat pumps primarily in the home air conditioning and heating context, they are an integral part of many products we use every day in our lives, including the heating and cooling in our cars as well as refrigerators and freezers in our homes, and more recently in water heaters.
In fact, the history of heat pumps used for water heating dates back over 70 years, most famously in an accidental discovery by Robert Webber when experimenting with the deep freezer in the basement of his home in Indiana.
Much has changed in the technology of heat pump water heaters over 70 years, and with new federal tax credits and utility rebates incentivizing home owners and home builders to install heat pump water heaters, demand is expected to grow significantly.
This class will help you to understand how heat pump water heaters work, provide a deep dive into the latest in heat pump water heater technology, and make it clear why you should strongly consider installing one in the homes you design, build and even the one you live in.
What we'll be learning:
- Why hybrid electric heat pump water heaters are significant to the US market
- How heat pump water heaters us the same principles of refrigeration to move heat rather than create heat
- The different types of heat pump water heaters
- The environmental benefits of heat pump water heaters
- The importance of proper site selection to maximize energy savings and home owner satisfaction
- Requirements for proper installation and maintenance

Ventilation in homes is important to maintaining good indoor air quality, and even more important as the International Energy Conservation Code (IECC) and national energy efficiency programs like ENERGY STAR have increased building tightness requirements.
Recognizing this, ENERGY STAR started requiring mechanical ventilation in version 3.0 in 2010 and the IECC adopted a robust ventilation requirement in 2012.
There are a number of ventilation strategies available to home builders, but it is generally agreed that "Heat Recovery Ventilators" and "Energy Recovery Ventilators", also known as "HRVs" and "ERVs", are the very best strategy.
In the coldest climates, the IECC 2021 and energy programs like the US Department of Energy's Zero Energy Ready Home program now require HRV/ERV's.
In this information packed class you will learn why HRV/ERVs are considered "the best" ventilation strategy, why this strategy is required in the coldest climates, and much, much more!
What we'll be learning:
- The most popular ventilation strategies for homes today
- What is a Heat or Energy Recovery Ventilator and how do they work
- Bust the common "myths" about HRV/ERVs, and learn the reasons why you would likely choose one for your own home
