1, cornice: it is the part of the roof (building) that protrudes from the external wall, and the width is generally not more than 50 cm.
2. Canopy: It is a building combination located at the entrance or exit of a building or above the top balcony.
Second, the function is different.
1, cornice: mainly for the convenience of roof drainage, but also to protect the external wall. Secondly, overhangs play an aesthetic role. Some sloping roofs and tiled roofs have no overhangs, and a few flat roofs with unorganized drainage have no overhangs.

Extended data:
A canopy can be divided into:
1, FRP canopy;
2. All-steel canopy;
3, PC board (sunshine board, endurance board) canopy;
4. Aluminum alloy canopy;
5, resistance plate assembly canopy
Second, the characteristics of the crown:
1. Safety: The glass cutting machine cannot effectively cut the installed laminated glass, and it takes a long time and makes a lot of noise for normal people to break through the laminated glass with other tools. Therefore, it is difficult to enter the room by cutting or breaking laminated glass, and it is easy to be found. Laminated glass has a strong ability to resist malicious destruction, theft and violent invasion.
2. Control the characteristics of sunlight: laminated glass (especially colored laminated glass) can weaken the transmission of sunlight, thus reducing indoor refrigeration energy consumption. At the same time, it can reduce the glare of sunlight and will not cause color distortion.
