Increasing Building Energy Efficiencies With Spaceloft Insul-Cap Nanotechnology Based Aerogel Insulation

Aspen Aerogels is introducing Spaceloft Insul-Cap, a new nanotechnology-based aerogel insulation product that adds R-value to wood- and steel-frame buildings, improving their energy efficiency.

Spaceloft Insul-Cap is made of a 3/8" thick strip of flexible aerogel blanket, the world's most efficient insulation material. The strips are applied onto a building's framing, inside or outside, prior to sheathing.

This eliminates thermal bridging, in which heat travels through the framing, resulting in heating or cooling loss.

Spaceloft Insul-Cap can add up to an R4.0 to standard wall framing, with dramatic results:

  • The thermal performance of a steel-frame wall can improve 40 percent, increasing to R11, the equivalent of a wood-frame wall.
  • A wood-frame wall's thermal performance can improve by more than 15 percent.

This can save the average homeowner up to $750 per year in energy costs and reduce the average home carbon footprint by several tons per year.

Spaceloft Insul-Cap's thin 3/8" profile allows it to fit between framing and sheathing without altering standard construction. It is applied in strips with a peel-and-stick adhesive backing or staples. It can be customized to fit on headers, rim joists, corners, rafters, window flashing and other hard-to- insulate areas.
