Wall Batts are specifically designed to deliver optimal performance in exterior cavity walls. You can lose up to 25% of the heat in your home through the walls in winter and around the same amount of heat can enter in through the walls during summer. Insulation essentially acts as a barrier to slow down this process and makes a substantial different to the temperature you will feel inside. Wall Batts can reduce energy used for heating and cooling by up to 20% leading to a decrease in your energy consumption and in your energy bills.
R-values are the measuring tool we use to rate the level of thermal resistance. Essentially, the higher the R-Value the more effective the insulation is. Wall batts are available in R-Values from R1.5 – R2.5.
