Narrowboat Windows: A Comprehensive Guide to Choosing the Best Options for Your Vessel
Narrowboat windows are an essential component of any narrowboat. They provide natural light and ventilation, and allow passengers to enjoy the scenery while cruising along the canals. Narrowboat windows come in a variety of shapes and sizes, and can be made from different materials to suit the boat owner’s preferences.
One of the most popular materials for narrowboat windows is acrylic, which is lightweight and shatterproof. Acrylic windows are also easy to clean and maintain, making them a popular choice for boat owners. Another popular material for narrowboat windows is toughened glass, which is strong and durable but heavier than acrylic. Toughened glass windows are also more expensive than acrylic windows.
Narrowboat windows can be fitted with various types of seals and trims to ensure they are watertight and secure. It’s important to choose the right type of seal and trim for your narrowboat windows to prevent leaks and damage to the boat. Overall, narrowboat windows are an important aspect of any narrowboat, providing both practical and aesthetic benefits to boat owners.

Narrowboat Windows Overview
Narrowboat windows are an essential part of any canal boat’s design. They provide natural light and ventilation while also allowing passengers to enjoy the scenic views along the canal.
Windows on narrowboats come in a variety of shapes and sizes, and can be made from different materials such as glass, acrylic, or polycarbonate. The type of material used depends on the boat owner’s preference and budget.
One of the most important factors to consider when choosing narrowboat windows is their ability to withstand the harsh weather conditions that canal boats often face. Windows that are not properly sealed or made from low-quality materials can lead to leaks and drafts, which can cause damage to the boat and make for an uncomfortable living space.
Another important consideration is the style of the windows. Some narrowboats have traditional porthole-style windows, while others have larger windows that provide a more modern look and feel. The style of the windows can also affect the amount of natural light that enters the boat, as well as the overall aesthetic appeal.
When it comes to maintenance, narrowboat windows require regular cleaning and inspection to ensure that they are functioning properly. Any signs of damage or wear should be addressed promptly to prevent further issues.
Overall, narrowboat windows are an important aspect of any canal boat’s design and should be chosen carefully to ensure that they provide both functionality and aesthetic appeal.
Types of Narrowboat Windows
Single Glazed Windows
Single glazed windows are the most common type of window found on narrowboats. They are typically made of either wood or aluminium and are relatively inexpensive. However, they are not as energy-efficient as double glazed windows and can be prone to condensation.
Double Glazed Windows
Double glazed windows are becoming increasingly popular on narrowboats. They provide better insulation and are more energy-efficient than single glazed windows. They are typically made of either uPVC or aluminium and can be powder coated for added durability.
Portholes and Hoppers
Portholes and hoppers are small, circular windows that are commonly found on narrowboats. They are typically made of aluminium and can be either single or double glazed. Portholes are fixed windows, while hoppers can be opened for ventilation.
Arched Top Windows
Arched top windows are a popular choice for narrowboats with a traditional or classic design. They are typically made of wood and can be either single or double glazed. Arched top windows provide a unique look and allow for more natural light to enter the boat.
Overall, there are a variety of narrowboat windows available, each with their own advantages and disadvantages. The choice of window will depend on the boat owner’s preferences, budget, and specific needs.
Materials for Narrowboat Windows
When it comes to choosing materials for narrowboat windows, there are several options available. Each material has its own advantages and disadvantages, and the choice will depend on the individual’s needs and preferences.
Wooden Windows
Wooden windows are a popular choice for narrowboats. They offer a traditional, classic look and are often used in older boats. They are also relatively easy to repair and maintain, and can be painted or stained to match the boat’s interior.
However, wooden windows require regular maintenance to prevent rot and decay. They are also not as durable as other materials and may need to be replaced more frequently.
Metal Frame Windows
Metal frame windows, such as those made from aluminium, are another option for narrowboats. They are lightweight, durable, and require little maintenance. They also offer a modern, sleek look that can complement a contemporary boat design.
However, metal frame windows can be more expensive than other materials, and may not be as well suited for traditional or vintage boats.
UPVC Windows
UPVC windows are a popular choice for narrowboats due to their durability and low maintenance requirements. They are also energy-efficient, which can help to reduce heating costs.
UPVC windows are available in a range of styles and colours, and can be easily customised to match the boat’s interior. However, they may not offer the same traditional look as wooden windows, and may not be suitable for vintage boats.
In summary, when choosing materials for narrowboat windows, it is important to consider factors such as durability, maintenance requirements, style, and cost. Wooden windows offer a traditional look but require regular maintenance, metal frame windows are durable but more expensive, and UPVC windows are low maintenance and energy-efficient but may not offer a traditional look.
Finishes for Narrowboat Windows
Narrowboat windows come in various finishes that can enhance the look of your boat. The most common finishes for narrowboat windows are powder coated, anodised, and wooden.
Powder Coated Finish
Powder coating is a popular finish for narrowboat windows. It involves applying a dry powder to the window frame, which is then heated to create a hard, durable finish. Powder coating is available in a range of colours, making it easy to match the finish to the colour scheme of your boat.
Powder coating is a cost-effective finish that is resistant to chipping, fading, and peeling. It is also easy to clean and maintain, making it an ideal choice for narrowboat windows.
Anodised Finish
Anodising is another popular finish for narrowboat windows. It involves treating the window frame with an electrolytic solution, which creates a hard, protective layer on the surface of the metal.
Anodised finishes are available in a range of colours and are resistant to corrosion and abrasion. They are also easy to clean and maintain, making them an ideal choice for narrowboat windows.
Wooden Finish
Wooden finishes are a popular choice for narrowboat windows, particularly for those who want a traditional look. Wooden finishes can be achieved using a variety of woods, including oak, mahogany, and teak.
Wooden finishes require regular maintenance to keep them looking their best. They should be treated with a protective coating to prevent water damage and rot.
In conclusion, the choice of finish for narrowboat windows depends on personal preference and the desired look of the boat. Whether you prefer a modern or traditional look, there is a finish that will suit your needs.
