Some homeowners look at impact windows for peace of mind, others choose standard insulated units because they are more affordable. The right answer depends on exposure, budget, and how much protection you want beyond normal replacement glass.

That is the best way to balance upfront cost with long-term performance in a hot, humid South Carolina climate.
