Thermablok, for shielding heat on space shuttles, is now available for construction

Thermablok is a new thermal nanotechnology now available to the construction industry.

The US-made product has been used as heat shielding on the space shuttle and in the space suits, which are subject to the most extreme temperature differences.


Thermablok claims to have the highest insulation properties of any material on the market (13.5mW/m.k. or 0.0078 BTU/ft-hr-F). While a typical 3.5” (89mm) of insulation in a stud wall has an R value of 13, using 3 ½” of this technology, could produce an R value of 105 in the same space.

Just one thin ¼”x 1.5” (9mm x 3mm) strip of Thermablok added to only one edge of studs in a wall can increase the insulation value by over 40%, according to the US Department of Energy test results.

The majority of thermal transmission in a standard insulated stud wall travels through the mechanical link, usually the studs.

Thermablok, which is 99.8% air, interrupts this thermal path quickly and economically.


Installation of the product is accomplished by attaching the product to the stud edge before drywall or sheeting is put up.

Thermablok comes with a simple pull and stick adhesive back for easy, clean installation. No messy adhesives required.
