Insulating Water Supply Pipes

R-value is a measurement that quantifies the resistance to heat flow of a given material. The higher the R-value, the greater the insulating power of that material. The R-value may not be displayed on pipe insulation, so you may need to do a little research. The colder your climate, the higher the R-value you should look for when choosing pipe
