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

Aerogel solution is thin and quickly installed in UK apartment interiors

Panels of Spaceloft 9251 laminated to
building facing board were easily attached
to apartment walls and around windows
and other fixtures.

The result was dramatically reduced heat
loss. These infrared photos show the
outside of a wall without aerogel insulation
(top) losing nearly twice as much heat as
the wall with aerogel insulation (bottom).
Heat loss appears as red, orange, and yellow.

• Provide insulation for UK government program to upgrade
  insulation in public housing apartment units.
• The insulation needed to improve the units’ 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 Spaceloft™ 9251 laminated to a building facing board.
• The insulation panel met the functional requirements with a total thickness of only 30 mm.
• Panels were easy to install, simply screwed onto the existing wall with no framing needed.

Benefits

• The Spaceloft 9251 solution cost-effectively met all energy targets. (Details below.)
• The Spaceloft 9251 solution was three times thinner than the nearest installed competitive solution due to framing requirments.
• Installation was 50% faster than the nearest competitive solution.
• Overall, the Spaceloft 9251 was the best space/cost solution.
