Abstract
Abstract A method of making a thermal insulating panel in which particles of microporous insulating material are put into a bag consisting of porous sheet material which is then subject to pressure to cause the particles to bond together and consolidate the insulating material and to create a tension strain in the material of the bag.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
A method of making a panel of thermal insulating material comprising, placing dry particulate microporous thermal insulating material having an average particle size less than 100 milli-micro-meters in a bag consisting of porous sheet material, sealing the bag to form a complete enclosure for the insulating material, and applying pressure to the exterior of the bag to thereby cause the particles to bond together and consolidate the insulating material, to cause particles of the insulating material to penetrate into the pores of the material of the bag and bond the insulating material to the bag, and to create a tension strain in the material of the bag.
Claim 2
Independent Claim
107 words
A method of making a panel of thermal insulating material comprising, placing dry particulate microporous thermal insulating material having an average particle size less than 100 milli-micro-meters in a bag consisting of porous sheet material, sealing the bag to form a complete enclosure for the insulating material, and applying pressure to the exterior of the bag to thereby cause the particles to bond together and consolidate the insulating material, to cause particles of the insulating material to penetrate into the pores of the material of the bag and bond the insulating material to the bag, and to create a tension strain in the material of the bag.
Claim 3
Dependent Claim
46 words
A method according to claim 1 wherein the insulating material is selected from the group consisting of microporous silica aerogel, alumina, zirconia and titania and the material of the bag is selected from the group consisting of glass fiber cloth, paper, cotton and porous synthetic plastic.
Claim 4
Dependent Claim
17 words
A method as claimed in claim 1 wherein the material of the bag is glass fiber cloth.
Claim 5
Dependent Claim
19 words
A method according to claim 1 wherein the insulating material consists essentially of microporous silica aerogel and an opacifier.
