Are storm windows a viable alternative to impact windows?

While storm windows offer an additional layer of protection, impact windows provide a higher, tested level of defense against severe weather. Impact windows are engineered with laminated glass, often bonded by a strong interlayer like PVB, which prevents shattering upon impact from wind-borne debris. Storm windows, while beneficial for reducing air and water infiltration, are not typically designed to withstand the same level of projectile force as certified impact windows. For robust protection against significant storm events, impact windows are the superior choice.
