They work by preventing water vapor in the air from reaching the wall surface, where it can condense into a liquid. Open-cell spray foam insulation typically has an R-value of 34 per inch. You can test this by leaving a stainless steel spoon standing in a pot with boiling water. The work of the insulation during summer is to keep the outside heat out of the house. Conduction and convection types of heat are both dealt with using bulk insulation. This happens because heat flows more readily through some building materials than through others, and this process is known as thermal bridging. In colder parts of the country, like climate zones six and seven, savings increases up to 20%. Foam board insulation is more expensive than traditional batt insulation, so use it only when moisture is a factor and it makes sense with your budget.
