We are finally ready to build and test a prototype! Choose a Category 3 hurricane and then the window protection and roofing materials you think will withstand the storm. Remember to always plan to spend as few “credits” as you can and still keep the home protected. Which combination gave you the best protection for the least cost?

To determine the best combination of window protection and roofing materials that provide optimal protection for the least cost during a Category 3 hurricane, we need to consider options that strike a balance between affordability and effectiveness. It's important to note that hurricane-resistant building materials can be costly, so minimizing expenses while ensuring sufficient protection is key.

For window protection, there are two commonly used options:

1. Hurricane shutters: These provide excellent protection against strong winds and flying debris. They come in various materials like metal, polycarbonate, or fabric, with metal being the most robust but also the most expensive option.

2. Impact-resistant windows: These windows are specifically designed to withstand hurricane-level winds and the impact of debris. They consist of multiple layers of glass or durable laminated glass.

Considering cost-effectiveness, hurricane shutters typically offer better protection for the cost involved. Therefore, we choose hurricane shutters as the window protection method for our prototype.

Regarding roofing materials, there are several options to consider:

1. Asphalt shingles: These are the most common and affordable roofing material, but they may not be suitable for high-wind environments without additional reinforcement.

2. Metal roofing: Metal roofs are durable and have excellent wind resistance. However, they can be more expensive compared to asphalt shingles.

3. Clay/concrete tiles: These tiles offer good protection, but they tend to be heavy and may require additional reinforcement for hurricane-prone regions.

Considering both cost and effectiveness, metal roofing is a reliable and relatively cost-effective choice for hurricane protection.

Therefore, for the prototype, the combination that provides the best protection for the least cost during a Category 3 hurricane would be:

- Hurricane shutters for window protection.
- Metal roofing for the roof.

This combination balances safety and affordability, offering strong protection against wind and debris while keeping costs minimized.
