R-value
R-value is a term used by the building and construction industry to define the thermal resistance a material has. The higher the R-value, the more resistance the product offers against heat transfer. Traditional insulation can vary vastly in the R-values it offers. The US Department of Energy has recommended R-values for certain areas in the [...]

The hottest trend is construction is converting an attic space into a living space. Unfortunately the term “hot” usually describes the room once it is complete. One of the common challenges is to get a decent amount of insulation between the sheetrock and the roof deck. Typically roof rafters are 2”x6” and allow only about [...]
There is some debate in the radiant barrier business whether to use a perforated or a solid radiant barrier product in an attic application. In an attic application, you should ALWAYS use a perforated product. Period. Why? Solid products like bubble foil insulation are called “Vapor Barriers”. A vapor barrier basically stops moisture from moving [...]
A common question is “What Is The R-Value of Radiant Barrier Foil?” The answer: ZERO Heat moves in 3 different methods: 1) Conductive 2) Radiant 3) Convective. R-Value is a term used to measure how resistant a product is to CONDUCTIVE HEAT ONLY. The best way to illustrate this is to picture an ice chest [...]
