Kingspan TW53 Thermawall Rigid External Wall Insulation If this is not possible, this linear thermal bridge can be reduced by insulating the reveal. The key factor is the thermal resistance (R–value) of this insulation layer. Reveals should be designed to accommodate the 20 mm of Kingspan Thermawall® TW53 required to achieve an R–value of 0.6 m2.K/W, and the depth of the cladding system Buy Insulation Board - Save up to 70% Free Delivery Over £300 Get familiar with the u-value . The lower the U value, the better the heat retention in the property. For example, when using a typical rigid board of 50mm, it is equivalent to a U value of around 0.4, 100mm is equivalent to 0.25 and 150mm and thicker is a U value of 0.2 or lower.

panels have more insulating value; therefore R-values increase with increasing panel thickness. These values are listed in Chapter 25, Table 4 of the 2001 ASHRAE Handbook published by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).
