Once installed, the 135mm isotherm insulation can have a 3 – 6 degree difference on indoor temperatures. Heaters will warm the indoors up much faster and aircons will cool down the rooms much faster. It pays for itself by reducing the electricity costs of energy-consuming heating and cooling systems.
