The present invention provides a preformed insulating layer having a flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web. Each protuberance has a length dimension, a width dimension, and a height dimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1. A uniform gap is left around each protuberance and is from about ⅛″ to about ½″.

A preformed insulating layer comprising a flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web having two arms intersecting at an intermediate portion of each arm, each protuberance has a length dimension, a width dimension, and a height dimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1, a uniform gap is left around each protuberance and isfrom about ⅛″ to about ½″, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion, wherein the end portion has a first end panel and a second end panel tapering toward each other inward of the arm. 2. The insulating layer of claim 1 wherein each arm has a base, a top and a face connecting the base to the top, the face tapering inwardly of the arm from the base to the top to form a first angle with a vertical axis, the first angle being from about 0 degrees to about 45 degrees. 3. The insulating layer of claim 1 wherein the first end panel has a surface that tapers inwardly of the arm from a base portion to a top portion and forms a second angle with a vertical axis from about 0 degrees to about 45 degrees. 4. The insulating layer of claim 1 wherein a distance between an end portion of one arm on a first protuberance to a second arm on a second protuberance is from about 0.125 inches to about 0.5 inches. 5. A preformed insulating layer comprising a flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web, each protuberance having two arms that intersect at an intermediate portion of each arm to form a first acute angle between a first portion of each arm, a second obtuse angle between a second portion of each arm, the first acute angle being between 65 degrees to 75 degrees and the second obtuse angle being supplementary to the first angle, each protuberance has a length dimension, a width dimension and a height dimension, a ratio of the length dimension to the width dimension is about 3:2, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion, the end portion has a first end panel and a second end panel tapering toward each other inward of the arm. 6. An insulating panel comprising: a first panel of a first flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web having two arms intersecting at an intermediate portion of each arm, each protuberance has a length dimension, a width dimension, and a height dimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1, a uniform gap is left around each protuberance and is from about ⅛″ to about ½″, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion, the end portion has a first end panel and a second end panel tapering toward each other inward of the arm; anda second panel stacked on top of the first panel, the second panel having a second flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the second web having two arms intersecting at an intermediate portion of each arm, each protuberance has a length dimension, a width dimension, and a height dimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1, a uniform gap is left around each protuberance and is from about ⅛″ to about ½″, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion. 7. An insulating panel comprising: a plurality of textured layers stacked on top of one another with peripheral portions being in registration to form a layered structure with alternating odd-numbered layers and even-numbered layers, each layer having a flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web having two arms intersecting at an intermediate portion of each arm, each protuberance has a length dimension, a width dimension, and a heightdimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1, a uniform gap is left around each protuberance and is from about ⅛″ to about ½″, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion, the end portion has a first end panel and a second end panel tapering toward each other inward of the arm, the length dimension of the odd-numbered layers extends along a first direction and the length dimension of the even-numbered layers extends along a second direction 90° to the first direction. 8. The insulating panel of claim 7 wherein the plurality of layers is from 2 layers to 10 layers. 9. The insulating panel of claim 7 wherein each arm has a base, a top and a face connecting the base to the top, the face tapering inwardly of the arm from the base to the top to form a first angle with a vertical axis, the first angle being from about 0 degrees to about 45 degrees. 10. The insulating panel of claim 7 wherein the first end panel has a surface that tapers inwardly of the arm from a base portion to a top portion and forms a second angle with a vertical axis from about 0 degrees to about 45 degrees. 11. The insulating panel of claim 7 wherein each of the arms have an end portion and a distance between an end portion of one arm on a first protuberance to a second arm on a second protuberance is from about 0.125 inches to about 0.5 inches. 12. An insulating panel comprising: a plurality of textured layers stacked on top of one another with peripheral portions being in registration with alternating odd-numbered layers and even-numbered layers, each layer having a flat web of metal foil having a plurality of spaced generally X-shaped protuberances deformed from the web having two arms intersecting at an intermediate portion of each arm, each protuberance has a length dimension, a width dimension, and a height dimension, the length dimension and the width dimension define a ratio of from 1:1 to 4:1, a uniform gap is left aroundeach protuberance and is from about ⅛″ to about ½″, each arm has an end portion having a width smaller than a width of the arm at an intermediate portion, the end portion has a first end panel and a second end panel tapering toward each other inward of the arm, the length dimension of the odd-numbered layers extends along a first direction and the length dimension of the even-numbered layers extends along a second direction 90° to the first direction;a first cover foil layer placed on top of the stack of textured layers and having peripheral edges in registration with the stack; anda pair of end caps encapsulating opposite ends of the cover layer and the stack of textured layers to maintain the individual layers in surface contact with one another and to prevent relative movement of one layer with respect to another layer. 13.
