R-Values (Construction)


“How can we measure a building material’s resistance to heat flow?”


One of a building’s primary functions is to insulate people from the outside world. And just as different materials are made of different atoms, different building materials are more efficient at producing insulation. So how can we quantify this? Well, let’s start by testing each material and assigning it a particular value. Engineers have done this and came up with the concept of the R-value. If you take a material of R-value x and one of R-value y and place one in front of the other then you will obtain a material with an R-value x + y. R-values are one of the fundamental components of modern-day construction
