An article includes a piece of encapsulated insulation including an envelope having at least two vents therethrough, a particulate insulation within the envelope, and a porous filter overlying each vent of the envelope. The porous filter has a mesh size no larger that the minimum size of the particles. The article may further include a structure having a structure surface, and the piece of encapsulated insulation overlies and covers at least a portion of the structure surface.

1. An article compatible for use in proximity to critical and/or sensitive components arranged in an environment, the article comprising: a piece of encapsulated insulation comprising an envelope having at least two vents therethrough;a particulate insulation within the envelope, wherein the insulation comprises a plurality of particles each having a size equal to or greater than a predetermined size;a porous filter overlying each vent of the envelope, wherein the porous filter has a mesh size sufficient to prevent passage of 0.5 micrometer particles through the porous filter so as to prevent the escape of any of the insulation particles from the envelope into the environment such that operation of the critical and/or sensitive components is not adversely affected; andwherein the particles are aerogel particles. 2. An article compatible for use in proximity to critical and/or sensitive components arranged in an environment, the article comprising: a piece of encapsulated insulation comprising an envelope having at least two vents therethrough;a particulate insulation within the envelope, wherein the insulation comprises a plurality of particles each having a size equal to or greater than a predetermined size;a porous filter overlying each vent of the envelope, wherein the porous filter has a mesh size sufficient to prevent passage of 0.5 micrometer particles through the porous filter so as to prevent the escape of any of the insulation particles from the envelope into the environment such that operation of the critical and/or sensitive components is not adversely affected; andwherein the particles are aerogel particles made of a material selected from the group consisting of inorganic, organic, or hybrid aerogel materials. 3. An article compatible for use in proximity to critical and/or sensitive components arranged in an environment, the article comprising: a piece of encapsulated insulation comprising an envelope having at least two vents therethrough;a particulate insulation within the envelope, wherein the insulation comprises a plurality of particles each having a size equal to or greater than a predetermined size;a porous filter overlying each vent of the envelope, wherein the porous filter has a mesh size sufficient to prevent passage of 0.5 micrometer particles through the porous filter so as to prevent the escape of any of the insulation particles from the envelope into the environment such that operation of the critical and/or sensitive components is not adversely affected; andwherein the particulate insulation comprises a fiber-reinforced aerogel composite. 4. An article compatible for use in proximity to critical and/or sensitive components arranged in a space environment, the article comprising: a piece of encapsulated insulation comprisingan envelope having at least two vents therethrough,a continuous monolithic aerogel insulation within the envelope, anda porous filter overlying each vent of the envelope, wherein the porous filter has a mesh size no larger than a minimum particulate size that may be shed from the continuous aerogel insulation,wherein the mesh size of the porous filter prevents any aerogel particles from passing out of the envelope and into the space environment such that operation of the critical and/or sensitive components is not adversely affected.
