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 support structure may have a base having surfaces including a top, a bottom, a front, a rear and sides. A first top slot may be formed in the top and may extend at least partially between the front and the rear. A second top slot may be formed in the top and may extend at least partially between the sides. In addition, a bottom slot may be formed in the bottom. A system for attic storage can include an attic having attic joists. A plurality of support structures, each comprising a base, may be mounted to the attic joists. At least two conventional lumber studs may be included and may extend between adjacent ones of the bases. In addition, a plurality of lumber panels may be mounted to at least one of the bases and the lumber studs.
