There isn t general rules to size an overhang.
How big should a awning be for rain.
Retractable awnings are designed only for sun protection.
In hot climates without heating requirements overhangs and shading devices should be large and cover the solar facade and possible adjacent outdoor living spaces.
The important aspect to keep in mind is that the awning should be installed at a proper pitch or slope.
Across our range the largest maximum widths are 7m for a single patio awning unit.
The size both width and projection along with the awning pitch and of course the density of the rain determine if pocketing will occur.
Pairing for a larger width if you were hoping for a projection wider than 7m many awnings can be coupled.
If you notice water pooling on the fabric you need to close the awning.
That will allow the rain water to run off the awning without pooling on the cover.
A 12 x10 awning has a surface area of 120 square feet.
However if you set the pitch steep enough the water will run off.
To help maximize the amount of rain that can be shed allow the installer to maximize pitch upon install and partially extend the awning as discussed above.
Most awnings we sell are around the 3m wide mark.
A light rain that drops 1 8 of rain will add 80 pounds of weight over the surface of the fabric.
At least 7 5 feet.
The optimum depth varies with the latitude and the type of climate.
The decision to retract or extend an awning when it s raining is more a matter of responsible judgment and your discretion.
The bigger the surface the more weight the arms must support.
