The different roofing systems Añuri uses come with different natural lighting systems and new materials on the market mean that alternatives can always be offered. In general, the skylights are made of plates with the same profiling as the material used for the rest of the roof.

The materials most commonly used on Añuri’s buildings are:

 Polyester.
This material is made from a polyester resin base reinforced with glass fibre. In order to improve the performance of the plates, the surfaces are coated with a layer of special polyester called GEL-COAT, whose photo-initiators smoke the skylight when activated by high-power ultraviolet rays. The GEL COAT protects the surface of the plates from the elements, guaranteeing a good level of transparency over the years.

Colours available: natural (or transparent), opal (or diffusion white) and frosted.

 Compact Polycarbonate.
These are 1-mm thick, grooved translucent plates made by extruding polycarbonate resins. Polycarbonate is a hard, naturally transparent, thermoplastic polymer.
Its considerable resistance to impact over a wide range of temperatures (from -40º C to 135º C) and its outstanding optical quality make it a perfect material for skylights. The outer face includes protection against the sun's ultraviolet rays.

Colours available: natural (or transparent), opal (or diffusion white) and frosted.

 Cellular Polycarbonate.
Using the same raw material as that described for the previous material, profiles comprising cells are obtained from the extrusion process. The cells are from 6 to 16 mm thick. The air trapped in the cells offers these plates insulation. The walls of the cells also enhance the plates’ mechanical properties.
