What is Cavity Wall Insulation?

Cavity wall insulation involves filling the gap between the inner and outer walls of a house with insulating material. This process helps to prevent heat loss, keeping your home warmer in the winter and cooler in the summer. Improved insulation can significantly enhance your property's Energy Performance Certificate (EPC) rating, making it more attractive to buyers and renters.

Why Cavity Wall Insulation is Important?

  • Energy Efficiency: Proper insulation reduces the amount of energy needed to heat or cool your home, leading to lower energy bills.

  • Environmental Impact: By using less energy, you reduce your carbon footprint, contributing to the fight against climate change.

  • Comfort: Insulation keeps your home at a more consistent temperature, increasing comfort year-round.
