When choosing roof insulation, consider both the R-value and the thickness needed to reduce energy consumption for your climate and home design. Some materials, such as polyisocyanurate (polyiso ...

There are three main types: polyiso, which has the highest R-value; extruded polystyrene (XPS), which is particularly ...

If the R value is higher than one, then the number of cases keeps increasing. But if the R number is lower the disease will eventually stop spreading, because not enough new people are being ...
