What is R-Value?

R-Value is a measure which tells about the thermal resistance of the insulating material to the conductive flow of heat. It is believed that greater the R-value, higher is the effectiveness of the insulating material.  So following are the R-values for Climate Zones 3 and higher as these areas require basement insulation.

Climate Zone 3: R-5

Climate Zone 4 (except Marine Zone 4): R-10

Marine Zone 4 and Climate Zones 5, 6, 7, and 8: R-15.

The very first step is the creation of stud walls, and it is must because as per the building codes, insulation must be covered and hence youhave to create these wall frames or stud walls. So start by installing wood boards of 2×2 after every 16″ throughout the basement walls. And, 2×4 pressure-treated boards for the bottom plates on the floor. Generally, the heights of the basements remain 8” but to make them fit on the bottom plate, you have to cut them a few inches from the bottom of the vertical boards. Here the thing which you have to keep in mind is that these boards should be just below the sill plate which is present on the top of the foundation wall. You must also get a rug like the Vintage Style Distressed Heat-set Area Rugs from The Rug Source to provide protection from floor leaks.

After that take a screwdriver to coerce concrete screws into the holes just created. After that, attach the vertical boards of 2*2 in the same manner, past that begin to fasten the screws every 2”, starting from the top.  Now it’s time to attach stud walls, so before attaching to the walls by the concrete screw that boards are perfectly leveled and are vertical.
