Soffit Board

Install a Soffit Board and never worry about water damage again. A soffit is a horizontal board or panel installed under a roof’s eaves. It covers the space between the roof’s edge and the exterior wall of the building. The main purpose of a soffit is to protect the roof’s underside from the elements and provide ventilation. Soffits typically consist of uPVC and come in various colours and styles to match the building’s exterior. They can also add visual interest to the building’s exterior and hide wires or pipes running through the eaves. At MB DIY, we offer three of the most robust and stylish types of Soffit Board: Hollow, Vented, and Flat Soffit Board.


Benefits of Installing a Soffit Board:

Several advantages come with installing a soffit board, and it’s vital to assess each project’s specific demands and requirements before beginning. Some of these advantages include:

  • Low Maintenance: Soffit boards need no treatment or much attention. Simply wipe them down occasionally, and they will look as good as new.
  • Low Budget: Soffit boards are inexpensive and require less upkeep than other options.
  • Durability: uPVC Soffit Boards are highly durable and won’t rot, crack, or rust like other materials such as wood or aluminium.
  • Increased Protection: Soffit boards protect the roof overhang’s underside from water damage and rot. They also keep pests like birds and squirrels out of the attic.
  • Increased Curb Appeal: Soffit boards improve a building’s appearance by giving the roof overhang’s underside a finished look.

Types of Soffit Boards:

Soffit Boards play an essential role in a building’s ventilation system, as they help regulate temperature and humidity levels within the building. They also contribute to a building’s energy efficiency by preventing hot or cold air from entering through the eaves.

Typically, there are three main types available: Hollow, Vented, and Flat. They also come in various sizes, including 150mm x 5m, 215mm x 5m, 250mm x 5m, 300mm x 5m, and 400mm x 5m. If you’re unsure which option is best for you, we’ve provided all relevant information below.

Hollow Soffit Board

One of the main benefits of using hollow soffit boards is their lightweight and easy-to-work-with nature. This feature makes them ideal for use in areas with limited access or where installing heavier materials may be difficult. They are also moisture-resistant, making them suitable for use in areas prone to high humidity or exposure to the elements.

Additionally, hollow soffit boards often require very low maintenance and don’t need painting or other ongoing maintenance. They are available in various colours and styles, making it easy to find a product that matches your home’s look and feel.

Vented Soffit Board

These boards have small holes or vents along its surface that let air circulate through the space between the soffit and the roof. This ventilation reduces the risk of mould and rot by preventing moisture build-up.

A hollow soffit board, on the other hand, has no holes or vents. It is simply a solid panel used to cover a construction element’s underside. Hollow soffit boards don’t provide any ventilation, so they might not be suitable in areas where moisture build-up is a concern.

In general, vented soffit boards are used in areas where ventilation is crucial, such as in attics or under a roof’s eaves. Hollow soffit boards may be used in areas where ventilation isn’t a concern or where a solid panel is desired for aesthetic reasons.

Flat Soffit Board

These boards are a horizontal panel used to cover the underside of an eave, roof overhang, or archway. The main difference between a flat soffit board and a vented soffit board is the presence of vents in the latter. While a vented soffit board adds protection and ventilation, a flat soffit board simply covers and protects the building.

Why Choose a Soffit Board?

It’s important to choose the right type of soffit board for your project based on the building’s specific needs and the local climate. If you are uncertain about which option is best for you, please contact one of our excellent staff members, who will happily assist you.

Overall, soffit boards are a convenient and durable choice for finishing a roof overhang’s underside. They also offer a number of benefits in terms of installation, maintenance, and aesthetics. There are three types of soffit boards, each with its own set of advantages.

Hollow soffit boards consist of lightweight material and have a hollow core. They are often used in residential construction and are easy to install and maintain.

Vented soffit boards have small holes or vents along their length, allowing for ventilation in the soffit area. These boards help reduce the risk of moisture build-up and improve airflow in the soffit area.

Finally, Flat soffit boards are solid panels with no holes or vents. They create a smooth, flat surface in the soffit area. Flat soffit boards are often used in commercial construction or situations where ventilation is not a concern. At MB DIY, we offer three of the most robust and stylish types of Soffit Board: Hollow, Vented, and Flat Soffit Board.
