Thermablok® Case Studies

Thermablok® Aerogel  Interior Wall Insulation Reduces U-Values by 44% and Lowers Energy Use and Carbon Emissions


  • Provide insulation for UK government program to upgrade insulation in public housing apartment units
  • The insulation needed to improve the unit’s U-values to save energy and reduce carbon emissions
  • The insulation also needed to be thin to minimize encroachment on living space in small rooms
  • Other requirements included water resistance, noise abatement, breathability and easy installation

Aerogel Solution

  • The Proctor Group developed a double layer of Thermablok® laminated to a building facing board.
  • The insulation panel met the functional requirements with a total thickness of only 30mm
  • Panels were easy to install, simply screwed onto the existing wall with no framing needed


  • The Thermablok solution cost-effectively met all energy targets (Details below)
  • The Thermablok solutions was three times thiner than the nearest installed competitive solution due to framing requirements
  • Installation was 50% faster than the nearest competitive solution
  • Overall, the Thermablok was the best space/cost solution

U-Value and Energy Savings from Installation of Thermablok

  • U-value reduction: 0.28W/m2K, (0.63-0.35 W/m2K), a 44% reduction
  • Energy reduction: 900 kWhr/yr
  • Carbon emmission reduction: 400 kg/yr
