ALUNA® Aluwall II roof, by its structure, is similar to typical winter gardens. Coupled directly with a building wall by means of a guide makes a house and a garden a harmonious entirety. Since segments can be drawn, during a sunny day one can take full advantage of the sun and in turn, when the weather is unfavorable, one can find shelter protecting from rain and wind. It is a perfect solution at large hotel objects, restaurants or SPA forming modern patios and winter gardens. Side walls of ALUNA® Aluwall II roof are nearly vertical and this enables maximal use of the space under the roof.
