In the past Isotherm, Insulation was one of our favourite thermal insulation products. However, in the last few years, we have been very disappointed by the slow decline in the product.
In our position as Insulation Installers for more than 30 years we are concerned about this situation. For this reason, we do not readily install the Isotherm Insulation. We have sourced a compliant version of polyester insulation.
