Studies have been conducted to determine the difference in cost between impact resistant windows and doors and other code approved products such as accordion shutters, roll down shutters and wind abatement systems. When comparing the cost of an impact window and non-impact product, it is important to make sure to look at comparable quality. By combining the cost of the non-impact product and the shutter system together, typically the additional cost to upgrade to an impact resistant product is minimal. However, the value to your home or building will increase by a greater percentage with the installation of hurricane impact glass as your structure will now have the highest and best form of hurricane protection.
