One Thermablok®  Strip
Increases R-Value up to by 40%




Thermablok® Flexible Blanket
ThermaBlok® Aerogel Insulation

Thermablok®

NASA developed Thermablok aerogel insulation, the most powerful insulation on the planet,  is the highest value material ever produced. It has the highest R-Value, unmatched physical and mechanical properties, will not age or be subject to mold, mildew or any environmental problems. Its hydrophobic, completely harmless, recyclable and environmentally safe.

One 10 mm Thermablok®  Strip Increases R-Value up to 40%
(When applied to all Steel Stud Faces)

Thermablok aerogel insulation blanket is a flexible composite material consisting of  aerogel embedded within a fiberglass matrix.
Thermablok®, available in self adhesive strips and blankets, posesses the highest insulating value (R-Value) per inch of any material on the planet. Thermablok® flexible strips and blankets are easy to install, maintain their R-Value and are completely recyclable while produced from harmless materials that are safe for you, your family and our environment.

Unlike previous aerogels, Thermablok's®  unique Patented process allows Thermablok® strips and blankets to be flexible maintaining their incredible properties under a wide range of conditions.  This is why, for the first time in history, aerogel insulation is available for home and commercial use.


What is aerogel?

Aerogel is an advanced material which holds 15 entries in the Guinness Book of Records for properties such as lowest density solid and best insulator. It is a silica-based substance, consisting of a loose dendritic network of the atom silicon. Aerogel is manufactured by delicately removing the liquid from a silica alcogel, replacing it with nothing but air, which makes up 99.8% of the final product. Some aerogels have a density as low as .001 grams per cubic centimeter (.0005 ounces per cubic inch).  This included video, from Lawrence Livermore National Laboratories,  demonstates aerogel and its properties.

ThermaBlok® is a flexible aerogel/fiber composite material, 3/8" (10mm) x 1 1/2" (38mm) wide x 4' (1.22m) long. It is installed directly to the edges of studs in the wall framing, before the installation of drywall. Thermablok has a peel and stick backing for quick and easy installation and is easily cut to size.

While sounding too good to be true, for something so simple to produce such incredible results, the figures are substantiated by the U.S Department of Energy's Oak Ridge National Laboratory and J. M. Laboratory, which compared two identical (metal stud/gypsum board) walls: One wall with one strip of the material on each 2x4 stud edge (one side only) and the second wall without the material. A 1/4" thickness of the material increased the insulation factor by 30%, and 3/8" increased the insulation factor by 42%.  This video, from the Discovery Channel, reveals this new flexible aerogel insulation material.
