For an insulation inspection during a building inspection, our handy guide – “25 Checkpoints for Inspecting Insulation Jobs” – covers all the bases, and then some. Intended to provide useful guidance on how to improve the quality of the installation of insulation products, the List has been created by our experts here at the Insulation Institute. It tells you what to look for when inspecting insulation in wall areas, as well as ceilings, floors and other areas.

No matter what you call it, air flow and its management are vital to the performance, energy efficiency and comfort of a new or renovated home. Not only that: improper air flow can have severe effects on the health and safety of the people in the building by promoting mold growth, spreading pollutants, and possibly creating backdrafting of combustion appliances, increasing the possibility of carbon dioxide poisoning.

Yes. The answer is simple, so this could be the shortest blog ever. However, given the misinformation that is out there it is worth explaining why R-value is in fact a good measure of thermal performance and dispelling some common misconceptions about it.

In the past three years working within the insulation industry I’ve had a many conversations with builders, contractors and our manufacturer members about getting Grade 1 installation using fiber glass batt insulation. Three conversations in particular stick out in my mind as both insightful and accurate: two separate conversations with The Green Building Curmudgeon, Carl Seville, and one with Toler Insulating owner Wayne Toler. Each conversation left me with this: when it comes to quality installation of fiber glass batts, you can’t get fast, good and cheap. So, you have to pick two. Or do you?

When it comes to energy costs, we all know the big numbers lie in heating and cooling the house. A large portion of this excessive energy use is due to air leakage as well as too little – or improperly installed – insulation. A good thermal boundary, which includes insulation, windows and doors, not only reduces energy waste, but also greatly increases an occupant’s comfort. Which brings us to heat flow. How heat flows, where it goes and how to control it is key to a whole-house systems approach that can create better homes for today’s homeowners.

Sound is everywhere and it has the ability to affect your mood, productivity and wellbeing. Nowhere is this more apparent than in the workplace, yet, many times, controlling for sound within the work environment is ignored. Insulation Institute spoke recently with Jeremy Luscombe, Marketing Executive for UK-based Resonics, a leading acoustics solutions provider about the impact of sound in the workplace, its effects on people and what can be done about it. The following Q & A was the result of that conversation:

Whether you’re building new construction or working on a renovation, you’ve got to think about preparing for and preventing the impact of water on the structure of the home. Because without your expertise, homes can easily have a drinking problem — and the water they absorb can be downright destructive.

KB Homes, a top 10 builder nationally, has firmly established itself as a leader in energy efficient building. In April of this year, it won its sixth consecutive Energy Star Partner of the Year Award. Additionally, in 2013, 2014 and 2015 it received Department of Energy Housing Innovation Awards for its Zero Energy Ready Home (ZERH) construction. With this level of success it begs the question “what are they doing?” DOE’s “Tour of Zero” website has detailed case studies on a number of homes (which we have written about before), including those from KB, but we will look specifically at the approach they took to insulation and air sealing in these homes, as well as the resulting ACH levels and HERS scores.

Images like this one are beautiful to me. Maybe it is my many years in the mineral (glass or rock based) fiber products industry, but when I see these products I find them beautiful. I know some see an old product, one they don’t think has changed much over time, but I see an ageless beauty that for over 80 years has been a sustainable choice for insulating our homes and businesses. Its sustainable qualities are numerous, but here are my top 6:

Net-Zero Energy vs. Zero Energy Ready Homes
Not all net-zero energy (NZE) homes are created equal, well, they aren’t all built the same that is. Also, slight differences in wording can mean different things. Did you know that there are net-zero energy homes and Department of Energy (DOE) Zero Energy Ready Homes (ZERH). What’s the difference? DOE defines a net-zero energy, or “zero energy,” building as “an energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.” [1] And a Zero Energy Ready home is “a high performance home which is so energy efficient, that a renewable energy system can offset all or most of its annual energy consumption.”[2] So, a ZERH is a building that has maximized its energy efficiency and has the potential to be a NZE home if renewable energy sources are added. Those are the definitions, but how they are built, and what products are used, to meet those standards, is up to the builder.
