A door includes a U-shaped frame having opposing side channels. The channels include peripheral, inner and outer walls with the inner wall being of a larger size and configuration than the outer wall. A glass insert slightly smaller than the size of the inner wall is inserted therethrough and is guided to a centered position seated upon the outer wall. An open frame insert is slid into the two side channels, and a plurality of opposing pairs of walls deflect the open frame insert into bearing engagement with the glass insert. A peripheral edge of the open frame insert defines a peripheral channel with a terminal edge of the door frame inner wall for receipt therein of a peripheral securing boss of an elastomeric peripheral seal.

A curved panel assembly as claimed in claim 4, wherein said backing sheet retainers each comprise a flange on the respective one of said abutment members, said flanges forming with said rear side of said member a pair of opposed concave recesses at the opposite ends of said rear side and said opposed concave recess receiving said second opposite marginal edge portions of said backing sheet.6. A curved panel assembly as claimed in claim 1, further comprising an elongate resilient retainer stretched between said abutment members, said resilient retainer having opposite ends in releasible engagement with said abutment members.7. A curved panel assembly as claimed in claim 1, further comprising elongate edge covers each extending along and engaged over said second opposite marginal edge portions of said backing sheet from one to the other of said abutment members.8. A curved panel assembly as claimed in claim 1, further comprising a curved support rod, said abutment members and opposite ends of said support rod having mutually releasibly engageable portions.9. A curved panel assembly as claimed in claim 1, wherein said abutment members each comprises a curved front plate and a backing sheet abutment formed separately from said front plate.10. A curved panel assembly as claimed in claim 9, wherein said abutment members are provided, at rear sides thereof, with formations shaped to engage and retain said backing sheet abutments.11. A curved panel assembly as claimed in claim 9, wherein said front plates each have a curved rear side, a rib extending along said rear side and a rearwardly open recess in said rib, and said backing sheet abutments are engaged in said recesses.12. A curved panel assembly as claimed in claim 11, wherein said backing sheet abutments each comprise a length of wire and a portion of said wire is engaged in a respective one of said recesses .13. A curved panel assembly as claimed in claim 1, including a support bracket, said support bracket having a pair of suction cups for connection to a rear surface of said backing sheets.14. A curved panel assembly as claimed in claim 13, wherein said support bracket comprises a length of metal bent to form a rear portion and a pair of arms extending at an inclination from said rear portion, said arms having free ends mounting said suction cups.15. A curved panel assembly as claimed in claim 14, wherein said support bracket is one of a pair of similar support brackets.16. A curved panel assembly as claimed in claim 15, including an elongate retainer member extending between and connected to said abutment members and said support brackets.17. A curved panel assembly as claimed in claim 1, further comprising metal extrusions engaged with said second opposite marginal edge positions of said backing sheets.18. A method of assembling a curved panel assembly, which comprises the steps of inserting opposite marginal edge portions of a backing sheet into retainers at opposite ends of a pair of curved abutment members having concave sides, with said backing sheet thereby having a concave shape facing said concave sides of said abutment members, and springing said backing sheet into abutment with said concave sides of said abutment members so as to thereby force said opposite marginal edge portions against said retainers and to form said backing sheet with a convex shape facing towards said concave sides of said abutment members, and to thereby releasibly connect said backing sheet and said retainers to one another. 19. An assembly comprising a pair of curved panel assemblies each comprising: upper and lower elongate curved abutment members;said abutment members each having an elongate concave rear side;backing sheet retainers extending rearwardly from said concave rear side at opposite ends of said concave rear side, said backing sheet retainers having a predetermined spacing from one another;a backing sheet;said backing sheet having first opposite marginal edge portions facing and abutting said concave rear sides of maid abutment members and second opposite marginal edge portions retained by said backing sheet retainers;said first opposite marginal edge portions each having a length greater than said predetermined spacing of said backing sheet retainers and said backing sheet being sprung into abutment against said rear sides of said abutment members with said second opposite marginal edge portions retained by said backing sheet retainers; andsaid abutment members being rearwardly open behind said first opposite marginal edge portions of said backing sheet so as to allow said backing sheet to be displaced to and fro perpendicular to said concave rear side;a connection between said panel assemblies.20. An assembly as claimed in claim 19, wherein said connection comprises a connecting strip having opposite longitudinal edges connected to said curved panel assemblies.21.
