What Are Cruise Ship Windows Made Of?

By Robert Palmer

Cruise ship windows, which are also known as portholes, are an integral component of any cruise vessel. Cruise ships rely on their windows for providing natural light and a view of the ocean for passengers to enjoy. But what materials are used to make these windows?

Typically, cruise ship windows are made from a combination of glass and steel. The glass itself is usually tempered, meaning it’s been treated with heat or chemicals to make it stronger and more resistant to breakage. This type of glass is highly impact-resistant and can withstand the forces generated by high winds and waves while still providing a clear view outside.

The steel frame that supports the window is usually made from stainless steel, which is strong enough to withstand the elements while also being corrosion-resistant. The frame also helps to ensure that the window remains securely in place during rough seas.

It’s important for cruise ships to use strong materials when constructing their windows as they must be able to withstand extreme weather conditions such as high winds, heavy rain, and large waves. Cruise ships must also be able to maintain their structural integrity during these conditions, so using materials that can stand up under duress is essential.


Cruise ship windows are typically made from tempered glass combined with a stainless steel frame. This combination ensures that the window remains secure during rough seas and can withstand extreme weather conditions while still providing passengers with a clear view of their surroundings.
