摘要 |
The invention relates to a thermally efficient and low maintenance enclosed structure (1), such as a sunroom (Figure 1), made from a framework of joined structural members (i.e., 10, 14, 15, 16, 17), thermally insulating kick panels (4), windows (5), optional door assembly (7), optional skylights (not shown) and a roof (19). The structural members include reinforced (14) and non-reinforced (12) polyvinyl chloride extrusions. The structural members are joined together at joints using hardware which cannot be seen from inside or outside the enclosure thereby enhancing the aesthetic appeal of the enclosure. Machines (44, 84, 120) for making the enclosure from a small number of extruded profiles are also described. |
