Abstract
Abstract Insulated panel structures comprising a pair of skins separated by an insulating barrier of foamed-in-place insulating material and having a recessed edge defined in part by a transparent rail which permits observation of the foam-filling process as the insulating material is inserted between the pair of skins. A connection for joining two insulated panels, each panel having a recessed edge to receive foamed-in-place material therebetween, and comprising a closure batten having a substantially T-shaped cross section, the foamed-in-place material acting upon the batten in cooperation with flexible locking flanges mounted on the edge of each panel to provide a tight seal.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
84 words
The panel connection of claim 1, the leg flange of said closure member being formed with shoulders located at a distance from said flange as to engage the ends of said resilient locking flanges when said cross flange is positioned in contact or near contact with the exterior of each panel, the pressure of said foamed-in-place material placing the shoulders in contact with the ends of said resilient locking flanges and providing an even tighter seal as the pressure of the foaming process increases.
Claim 2
Dependent Claim
51 words
The panel connection of claim 2, the cross flange having parallel edges extending toward the skins of said panels and engageable therewith, said edges being resilient to bias the cross flange away from the panels while allowing the shoulders to be positioned within the cavity in back of said locking flanges.
