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 each have a vertical portion and support assembly extending inwardly, including an upper support surface, a lower support surface, and a vertical step therebetween. A glass setting block made of a rubbery material rests upon the upper support surface, vertical step, and 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.

A retention system may comprise a bracket, a bar system, a seal and a bonded washer. The bracket may have a first portion and a second portion. The first portion and the second portion may be operatively coupled together at an angle θ. The bracket may also have a texture. The bracket may define a mounting surface. The bar system may comprise a bar installable in the bracket. The seal may be installable in the bracket and disposed beneath the mounting surface. The bonded washer may be installable on and compressible against the mounting surface.

A spacer member, for allowing a walkable skylight with an insulating glass unit to be created with a structural glass panel and a thermal glass panel. The spacer member includes a slab part and a tube part having substantially the same thickness. The tube part is hollow, containing desiccant material for absorbing moisture within the insulating glass unit. The spacer members may be joined together to create a spacer frame. The spacer frame defines an inner rectangular region. When the spacer frame is sealed between the structural glass panels and the thermal glass panel, an air gap is created within the inner rectangular region. The desiccant material effectively removes moisture from air within the air gap.

A curb-mounted skylight designed for mounting on a framing protruding from the roof and forming part of its construction. The skylight has a glazing unit (1) and a support frame (2), where the distance (H2) from the skylight support surface to the outermost edge of the protective wall (22) of the section profile of the support frame (2) is not longer than the distance (H1) from the skylight support surface to the outside surface of the glazing unit (1). There is an adhesive sealing joint (5) between the glazing unit (1) and the protective wall (2).

A shear transfer system is provided. In the system, a shear tie strap is attached to a first framing member, a second framing member, a third framing member, a fourth framing member, and a fifth framing member of a frame in a framed building. The second, third, fourth, and fifth framing members are orthogonal or oblique to the first framing member. More than one shear tie strap may be present in the framed building.
