Knowing what parts would greatly affect your windows’ state can help a lot in times of need.

There’s so much more to know about your boat windows. Whether you’re looking to replace, repair or just check it out for damages, knowing these important boat window parts will come in handy.

The Glass Parts

The most obvious part in every window is the glass. In marine and boat windows, glass materials can vary depending on the type of window it will be used. 

Marine glass materials are made to survive the pressures of the wind, water and other marine and water sports activities. Most boat window glass in the market are made up from these materials:

Vinyl and Polyester Composite

These materials are known to be more flexible than the others. It can bend or curve to the contours of the boat seamlessly. This composite combination makes its fabrics stay tightly against the window’s frame. These waterproof fabrics also help avoid the development of mildew.

Clear Pressed Polished Coated Vinyl 

One of the most popular choices for marine use is the clear pressed polished coated vinyl. It’s the easiest to maintain because of its scratch-proof coatings. This material can be easily rolled back which makes it best for the roof and tops of boats.


Window glass made from polycarbonate materials are considered to be unbreakable, or that it seems like it is. This material is known to provide the best visibility for the user as it’s clearer than other plastics. 

However, it also has a downside: since it’s not soft like vinyl, you cannot roll it up for storage. Polycarbonate tends to get a little more pricey too.


Also another almost unbreakable material, acrylic tops the choice of users as it also provides better visibility. It’s most advisable for rugged marine use.  The acrylic has the ability to withstand a lot of air and water pressure.

The downside, however, like the polycarbonate, you cannot roll it up for storage. Acrylics also tend to get scratched easily.
