A structural or flexible highly insulative panel which may be translucent, is formed from multi-layer polymeric material in the form of an envelope surrounding a baffle. The baffle is designed so as to minimize heat transfer across the panel, by using material which forms substantially closed spaces to suppress convection of the low conductivity gas fill. At least a portion of the baffle carries a low emissivity surface for suppression of infrared radiation.

A lightweight, highly insulative panel comprising a gas envelope enclosing an expandable and flexible baffle means, wherein; A. said gas envelope means comprises a single, folded sheet or a two sheet polymeric film joined at the edge and having first and second gas envelope faces; and B. said baffle means comprising a shaped thin sheet core material having at least one surface with an infrared reflective coating that imparts an infrared emissivity of about 0.3 or less and providing 1. separate gas containing chambers with an average thickness of about ⅛to ½inches measured approximately normal to said gas envelope faces, and no more than five inches in one direction parallel to said gas envelope faces, and whereby said chambers restrict the flow of gas between adjacent chambers during operation but allow for forces exchanges of the gas within said chambers during manufacture or installation; and 2. a configuration of said core material such that core materials having extension in the direction normal to said envelope faces are assembled such that adjacent layers in the direction normal to said envelope faces of gas chambers are staggered or angled with respect to the direction normal to said envelope faces, such that the majority of paths through the core material have lengths that are longer that the shortest dimension distance between said faces.
