The title is the question.
Maybe it’s the cheapest thing with the right properties, but can’t it be painted with something a little more reflective, that won’t absorbe so much heat from the sun?
In: Technology
It’s cheap, highly available, easy to install, cures quickly, produces very little running noise, and can be removed easily for the next replacement.
Unfortunately, it wears and settles as an absurdly slow-moving liquid when subjected to extreme pressure, like say under the tires of a truck or bus, and it retains heat due to its chemical properties and low albedo (absorbs more light than it reflects, hence it retains the heat energy).
It’s a tradeoff that needs careful consideration, but the pros often outweigh the cons.
