Attic Trusses: An Introduction
Attic trusses, also known as room-in-the-roof trusses, are a type of roof truss system that incorporates the use of an attic space within the roof structure. These trusses are designed to allow for additional living or storage space in the home’s attic, making them a popular choice for homeowners looking to maximize their usable space.
Common Types of Attic Trusses
There are several different types of attic trusses that can be used in residential construction. Each type has its own unique design and capabilities, making them suitable for different applications. Here are some of the most common types:
Traditional Attic Trusses
Traditional attic trusses are the most basic type of attic truss, commonly used in residential construction. These trusses are designed to create an open attic space that can be used for storage or converted into living space. Traditional attic trusses typically feature a simple triangular shape, with a horizontal bottom chord that provides support for the roof above.
Raised Heel Attic Trusses
Raised heel attic trusses, also known as energy heel trusses, are designed to provide additional insulation space in the attic. These trusses feature an elevated heel, which creates a larger area for insulation at the eaves. This design helps to improve energy efficiency and reduce heat loss through the roof. Raised heel attic trusses are commonly used in climates with cold winters and are an excellent choice for homeowners looking to maximize energy efficiency.
Attic Trusses with Dormers
Attic trusses with dormers are a more complex type of attic truss that incorporates additional structural elements to create dormer windows or extended roof sections. Dormers are typically used in attic spaces to create additional headroom and natural light. Attic trusses with dormers are a popular choice for homeowners looking to add aesthetics and architectural interest to their homes.
