The bases of the light domes are absolutely necessary for the installation of the light domes. The adjustment bases provide a flat base for placing the light dome, and at the same time they are also the supporting element of the light dome. They are made of polyester resin reinforced with fiberglass. A hard polyurethane foam filler is used as thermal insulation. The inner side of the setting base is smooth and made in white, which is not a requirement. Depending on the customer's request, the guide ring can be made in a color shade according to the RAL scale. The height of the adjustable base depends on the mounting location and the thickness of the roof insulation; the recommended height of the adjustable crown is the thickness of the roof insulation + 20 cm. The component parts of the adjustable base are: the frame of the adjustable base with or without a condensing nose with a wooden or metal insert, the wall of the adjustable base with a standard insulation thickness of 25mm and the heel of the adjustable base. The setting bases are installed on the prepared substructure:

- wooden structure
- concrete substructure
- metal construciton
- sheet metal supporting elements
