The center pivot design comes with a full perimeter gutter to catch rain water from all sides and direct it where the customer wants it to go.
The louvers are easily connected to a pivot bar which rotates the them to open and close all at the same time.
The bottom pivot design allowed for louvers up to 24’ long supported by and connected to rafters beneath every 3 to 4 feet. The louvers on this design are typically only 4” which restricts more natural light plus they can only open a little past 90° so they are unable to shade and catch light beyond that point.
The bottom pivot design makes the louvers top heavy so that when they close passed the 90° point the weight transfer creates as much as 500 lbs. of stress on the motor and mechanism.
Because rafters are needed every 3 to 4 feet the look of the bottom pivot design is less appealing. The louvers sit on top of the rafters and the rafters sit on top of the beams giving a stacked look.
The mechanism to open and close the louvers is internal in each of the rafters and hard to get to with mechanical problems. When this happens all of the louvers must be removed to gain access to the mechanism.
The new generation louvered roofs have quite a few improvements. These are directed toward allowing the customers even more time spent on the patio as well as taking advantage of new technologies and improved strength in structure design.
There are several new generation louvered roofs now manufactured in countries across Europe including Spain, Belgium, and Italy and 3 manufactured in the USA. None of these manufactures have elected use the bottom pivot design.
Here is a list of some of the improvements these company have in their designs:
