7 Minutes of BS (#BuildingScience w/a BEAT)

Heat Flow

Guest Jonathan Smegal, from RDH Building Science Laboratories, explains the mechanisms of heat flow, and how it can actually flow around insulation.

Wind Resistance

Guest: Dr. Anne Cope, Ph.D., P.E., Chief Engineer of the Insurance Institute for Business & Home Safety explains why calling it hurricane resistance puts so many people at risk.

EFFECTIVE R-Value:

Can a wall plummet from R-50 to R-12 because of the studs?
In this episode, we are joined by Jonathan Smegal, M.A. SC a Senior Project Manager with RDH Building Science Laboratories breaking down the nuts, bolts, what, why and how of R-value, insulation, and building assemblies.

Dew Point

This time we discuss dew point with Dr. Allison Bailes, aka, the Energy Vanguard.
“Dew point is the temperature at which water vapor in the air will condense on surfaces. So, if you have a surface that is at the dew point temperature of the water vapor that’s in the space around that surface, the water vapor will start condensing on that surface."

Stucco

“Stucco is an exterior finish, and more specifically, we tend to think of it as an exterior plaster finish.
In some of the literature and in architectural dictionaries, stucco can be used for both exterior and interior finish work, but really in this day and age, we talk about plaster, particularly in North America, for interior work.”
—Sarah Gray, an engineer with RDH Building Science

ViscoElasticity

"ViscoElasticity is what we’re talking about and that is the property of a material that exhibits the viscous nature of a liquid but also the elastic nature of a solid." —Allen Sealock, the product director for ZIP Systems with Huber Engineered Woods talking about the pressure-sensitive adhesives that are used on construction tapes.

The Psychrometric Chart

Psychrometrics is the physics which deals with the process and properties of moist air, a combination of water vapor and dry air.

Low-E Coatings for Glass

Low-e coatings screen infrared heat from moving through windows, either inward, outward, or both
Today Ray Garries, Vice President of Engineering and Innovation at MI Windows and Doors joins the show to explain what low-e coatings are, how they work, and why they matter for windows in your home.

Unvented - Roofs

Like an out-of-plumb wall, insulated and unvented roofs can work well—or not.
In this episode, we are joined by Jonathan Smegal, M.A. SC a Senior Project Manager with RDH Building Science Laboratories breaking down the nuts, bolts, what, why and how of an unvented roof assembly.
