A skylight assembly, having framing members that define an interior space and rafters that span the interior space between framing members, for supporting panes of glass, each pane having at least one structural glass panel and a thermal panel. The framing members have an upper support surface and a main gutter. A structural thermal break connected to each framing member provides a lower support surface. The structural glass panels are fully supported by the upper support surface. The thermal panel is supported by the lower support surface, and is sealed to the upper support surface by a spacer, forming an insulating glass unit therewith. The full support of the structural glass, independent of the support of the thermal panel, allows the skylight to be thermally insulated and walkable. Support blocks extending on each rafter have drainage channels that lead to the main gutters in the framing members.

A floor covering system (10) with (a) a PVC-based floor covering (100) and (b) a lighting system (200) arranged to generate light (210). The PVC-based floor covering (100) has a user side (101) and an opposite back side (102). The lighting system (200) is arranged at the back side (102) of the PVC-based floor covering (100). The PVC-based floor covering (100) has a light transmission for light (210) generated by the lighting system (200) in the range of 0.5% to 30%, especially in the range of 1% to 20%.

A flooring system combines a dimensionally stabilized sub-floor laminate with a dimensionally stabilized tile laminate, the sub-floor laminate and the tile laminate being held together by magnetic attraction. In one embodiment one or other of the laminates is magnetic, and the other has a ferromagnetic engagement sheet. In another embodiment, a magnetic intermediate sheet is placed between ferromagnetic strata of the two laminates. The tile laminate may include ceramic tiles, which may be glass or porcelain. Those tiles are substantially rigid. They have flat ground edges to provide abutting matching fit with adjacent tiles. On assembly, neither mortar nor grouting is employed. The sub-floor has pre-defined mounting hardware accommodations that permit the fasteners not to interfere with the flatness and fit-up of the laminates.

A method of vacuum sealing a sacrificial panel to a structural panel, such as to form a walkway, is disclosed. The method comprises providing a sacrificial panel having a first side and a second, opposing side, providing a plurality of dots, applying the plurality of dots in a spaced relationship onto the first side of the sacrificial panel, applying a double-sided tape about the periphery of the first side of the sacrificial panel, providing a structural panel, placing the structural panel onto the first side of the sacrificial panel, wherein the dots create a gap between the sacrificial layer and the structural layer, and the double-sided tape provides an airtight seal between the sacrificial layer and the structural layer. The method further comprises providing a needle coupled to a vacuum device, inserting the needle into the gap between the sacrificial layer and the structural layer and operating the vacuum device to remove air from the gap between the sacrificial layer and the structural layer.
