Product Selection Guide

Aspen Aerogels’ Spaceloft™ and Pyrogel^® materials are thin, flexible nanoporous aerogel insulation blankets designed to meet extreme thermal requirements for a broad range of applications.

These products can be put into continuous service at temperatures ranging from –273°C/-532°F up to 650°C/1200°F, with thermal conductivities ranging from 2-10 times lower than typical insulations. Several grades of these products are opacified to reduce the impact of IR on thermal performance at higher temperatures. Products come in a range of roll sizes, and fabricated systems are also available.
