The characteristics of a glass ceiling

A glass ceiling can be laid with 2 kinds of materials, glass slabs or cobblestones. In both cases it isa special glass whose thickness varies according to use. If it is a skylight on which it is possible to walk (intended to illuminate a basement or a lower room for example), the thickness and strength of the glass will be a function of the size of the glass floor and the height that lies below. The higher the height, the thicker the glass should be. In the case of a single glass ceiling facing outwards (in the form of slabs or paving stones), particular care will be taken in the joints between the various elements in order to avoid possible leaks and to the weight from the whole.

Careful laying of a skylight

Pavers and glass slabs are heavy. Their installation must therefore be carried out by a professional who will study the floor that must receive them, the location and the most appropriate size of the glass ceiling according to these criteria. The laying of the slabs is then done insidea metal frame on which rests neoprene wedges that prevent the glass from breaking under the weight.
Some specialty manufacturers offer panels that are designed to meet the most common needs. But beyond one square meter, it will be better to have the project studied by a professional because handling and installation are very delicate.

The different glass floors

If the thickness of the skylight or glass ceiling depends on certain criteria, it is possible, under certain conditions, to choose its finished appearance. Transparent or frosted glass, smooth or textured (grained, grained, corrugated, diamond...) or even colored, there are many possible finishes. It depends on the desired light output.

Budget side, it takes about 650 euros / m² for a glass ceiling. A high price that is explained by the technicality required for installation. Glass-paved panels are a little less expensive.
