Is this insulation good for limiting excess heat gainIncrease in the amount of heat in a space, including heat transferred from outside (in the form of solar radiation) and heat generated within by people, lights, mechanical systems, and other sources.

The fogging material is usually a glycol-based solution, completely non-toxic. up easily. Will inner storm windows prevent the fogging and provide more R-value? Can you suggest other alternatives?
