Skylights are mostly aluminum alloy and steel structure, which are fixed by multiple columns or expanded steel nails into the wall. Awning, as a common household item, can keep out the sun and rain, but it can't resist strong winds.

The sun room is made of steel structure and tempered glass, which is fixed and transparent as a whole. It can not only receive the heat of the sun well, but also shelter from the wind and rain, which is very useful in spring, autumn and winter. Moreover, the sun room can be used as an indoor space, and it is a good choice to put things, tea room, gym, study and greenhouse. But this traditional fixed sun room is too stuffy in summer, and the surrounding windows can't solve the indoor heat dissipation.

On the basis of the original fixed sun room, the mobile telescopic Supreme Carl Sun Room can be folded and opened at will, shrinking most of the sun rooms, restoring the original outdoor appearance of the roof and solving the problem of ventilation and heat dissipation.
