<p>A foam-filled thermal insulation panel comprises metal side sheets (14,16) and an extruded plastics edging strip (20;22) which together enclose a cavity filled with foam (18). The edging strip comprises slotted edge portions which receive inturned edge flanges (24,26) of the side sheets, so relatively locating the components and eliminating the usual need for jigging during in-filling with the foam. The edging strips of adjacent panel edges to be connected have complementary male (28) and female (38) forms to enable the panels to be snap-fitted together, the strips so serving both to connect the panels and provide a seal between them.</p> |
