FAQs

How do you calculate the thickness of insulation needed? The thickness of insulation needed depends on various factors, including the desired R-value (thermal resistance), local climate, and building materials. To estimate insulation thickness, you can use the formula: Thickness (inches) = R-value / RSI (thermal resistance of the insulation material in m²·K/W). Typically, for residential applications in moderate climates, you might aim for an R-value of around 38 for the ceiling and 19 for walls.

How do you calculate insulation thickness to avoid condensation? To prevent condensation, you need to consider the dew point temperature. The insulation thickness should ensure that the interior surface temperature of the insulation remains above the dew point temperature. Use the formula: Thickness (inches) = (Surface Temperature – Dew Point Temperature) / (R-value per inch). Proper ventilation and vapor barriers are also important in condensation prevention.
