When you try to replace a screen section, (on a pool enclosure, porch, patio or other) and the outside temperature is below 70 there is a problem.
In cooler temperatures the spline (black rubber tubing that keeps the screen in place) gets like hard plastic and is difficult to work with and when the temperature gets below 60 it is almost impossible to work with.
Because of the rigidness of the spline (tubing) the screen may tare . The screen material also becomes more brittle and may tare easier when you work with it.
So, even though you may want to replace your screens ASAP, it is better to wait until the outside temperature is above 70.
