A building or insulating panel (30) including a collapsible frame of generally square or rectangular configuration, which is collapsible between a generally flat condition and an erected condition in which it is installed. The frame including overlying top and bottom sheets (31,32) that are generally parallel and spaced apart in the erected condition of the frame by two webs (33,36) which are spaced apart to extend in generally parallel realationship lengthwise along opposite side regions of the frame. The webs (33, 36) extend substantially perpendicular to the top and bottom sheets (31, 32) in the erected condition and are disposed substantially parallel to the top and bottom sheets (31, 32) in the collapsed condition. The panel further includes reinforcing means (37) which is inserted between the top and bottom sheets (31, 32) when the frame is in the erected condition to reinforce the panel (30) against collapse. The insulating panel may have an intermediate sheet disposed between the top and bottom sheets which is adhesively connected to each of the top and bottom sheets. The intermediate sheet is formed as a corrugated sheet and at least one of the top and bottom sheets and the intermediate sheet are formed from reflective insulating foil to create a reflective air space.

The invention claimed is: 1. A method of assembling a building panel, the method comprising the steps of: providing a collapsible frame of generally square or rectangular configuration, which is collapsible between a generally flat condition, and an erected condition, said frame including overlying top and bottom sheets that are generally parallel and spaced apart in said erected condition of said frame by two webs which are spaced apart to extend in generally parallel relationship lengthwise along opposite side regions of said frame, said webs extending substantially perpendicular to said top and bottom sheets in said erected condition and being disposed substantially parallel to said top and bottom sheets in said collapsed condition, expanding said frame to said erected condition and thereafter inserting reinforcing means between said top and bottom sheets, the reinforcing means and the wens extending lengthwise along entire lengths of the opposite side regions of said frame; and placing said erected building panel in an installed position in a building. 2. A method according to claim 1, said reinforcing means being of sheet form and being collapsible between a generally flat condition and an erected condition, said reinforcing means being formed into said erected condition for insertion between said top and bottom sheets of said frame. 3. A method according to claim 1, said reinforcing means being formed as a member which is shaped ready for insertion between said top and bottom sheets of said frame, said shape of said reinforcing member being such as to permit nesting between a plurality of said reinforcing members. 4. A method according to claim 1, said reinforcing means having a corrugated form for insertion into said frame, said corrugated form defining successive oppositely facing peaks respectively extending into contact with said top and bottom sheets of said frame. 5. A method according to claim 4, said corrugated form being of generally curved form. 6. A method according to claim 4, said corrugated form comprising a generally sawtooth profile. 7. A method according to claim 4, said reinforcing means being arranged to engage said webs. 8. A method according to claim 1, said panel including at least a further web disposed between said webs at said opposite side regions of said frame and extending generally parallel thereto and substantially perpendicular to said top and bottom sheets in said erected condition of said frame and being disposed substantially parallel to said top and bottom sheets in said collapsed condition of said frame, said reinforcing means being provided between at least one pair of adjacent webs. 9. A method according to claim 8, wherein said at least a further web is a single further web. 10. A method according to claim 9, wherein said further web is disposed substantially midway between said webs at said opposite side regions. 11. A method according to claim 8, including a pair of further webs. 12. A method according to claim 1, said frame including an intermediate sheet disposed intermediate and substantially parallel to said top and bottom layers and having plan dimensions substantially the same thereas and said webs being arranged to support said top and bottom sheets and said intermediate sheet in spaced apart relationship. 13. A method according to claim 1, said top and bottom sheets and said webs being formed of cardboard or cardboard-like material. 14. A method according to claim 1, said panel being formed as an insulating batt, in which said top and bottom layers are formed from reflective insulating material. 15. A method according to claim 14, wherein said reinforcing means is formed from reflective insulating material. 16. A panel made according to the method of claim 1. 17. A method of installing a building panel, the method comprising: providing a collapsible frame of generally square or rectangular configuration, which is collapsible between a generally flat condition, and an erected condition, said frame including overlying top and bottom sheets that are generally parallel and spaced apart in said erected condition of said frame by two webs which are spaced apart to extend in generally parallel relationship lengthwise along opposite side regions of said frame, said webs extending substantially perpendicular to said top and bottom sheets in said erected condition and being disposed substantially parallel to said top and bottom sheets in said collapsed condition; and as a first step, either of 1-transporting said frame to an installation site, or 2-expanding said frame to said erected condition and thereafter inserting reinforcing means between said top and bottom layers of said frame, the reinforcing means and the webs extending lengthwise along entire lengths of the opposite side regions of said frame then conducting the other of these steps and thereafter placing said erected building panel in an installed position in a building. 18. A method according to claim 17, wherein said transportation step is the first step conducted and for that step, said frame is transported in said collapsed condition. 19. A method according to claim 17, said reinforcing means being collapsible between a generally flat condition and an erected condition, said method including transporting said reinforcing means in said flat condition to said installation site and thereafter expanding said reinforcing means to said erected condition prior to insertion thereof into said frame. 20. A method according to claim 17, said reinforcing means being formed as a member which is nestable with other reinforcing members and said method including transporting a plurality of said reinforcing members to said installation site in a nested condition. 21. A method according to claim 17, said panel being an insulating batt. 22. A panel made according to the method of claim 17.
