“Build Better with Steico I Joists The Future of Construction!”


The Steico I Joist: A Revolution in construction

Construction has come a long way over the years, with new technologies and materials being introduced to make buildings stronger, more energy-efficient, and environmentally friendly.

One such material that’s gaining popularity among builders is Steico I-Joists. The use of Steico I-Joists in  passive house construction projects is becoming increasingly popular, and it’s easy to see why.

This innovative product offers a range of benefits that make it an ideal choice for those looking to build prefab homes for sustainable living conditions that last a lifetime.

What are Steico I Joists?

Steico I-Joists are engineered timber beams that are used to construct floors, walls and roofs.

An I-joist, also known as an engineered wood joist, is a structural component used in construction. It consists of a top and bottom flange made of solid-sawn lumber or laminated veneer lumber (LVL), and a web made of oriented strand board (OSB) or other engineered wood material.

The flanges and web are assembled together to form a rectangular or I-shaped profile, hence the name “I-joist”.

I-joists are used in wall. floor and roof construction and are known for their strength, stability, and dimensional consistency, which makes them an ideal choice for passive house construction projects.

They are also lightweight, easy to handle, and can span long distances, making them well suited for larger buildings.

How do I joists work together?

I-joists work by transferring loads from the floor or roof deck to the building’s foundation. The solid-sawn lumber or LVL flanges provide the primary strength and support for the floor or roof, while the web made of OSB or other engineered wood material provides stability and stiffness.

When installed in a building, I-joists are typically laid parallel to one another, spanning the distance between the walls or supports.

The flanges are then connected to the floor or roof decking material, and the web is fastened to the walls or supports to create a rigid frame.

As loads are applied to the floor or roof, they are transferred through the decking material to the I-joists, which distribute the load evenly across the building’s foundation.

This provides a strong and stable support system for the building and helps to prevent structural deformation, even under heavy loads.

The strength and stability of I-joists are also enhanced by the use of engineered materials, such as LVL and OSB, which are carefully designed and manufactured to provide consistent performance and meet specific strength requirements.

This makes I-joists a reliable and efficient choice for modern construction projects.

Are Steico I Joists better than Timber Joists?

I-joists are engineered wood products that offer several advantages over traditional timber joists:

  1. Strength and Stability: I-joists have a flange made of solid-sawn lumber, with an engineered web that provides uniform and consistent support. This results in a more stable and stronger structure compared to traditional timber joists.

  2. Lighter weight: I-joists are lighter than timber joists, making them easier to handle and install. This reduces the overall weight of the structure, which is important for multi-story buildings.

  3. Longer spans: I-joists have a longer span capability than timber joists, allowing for greater open spaces.

  4. Cost-effectiveness: I-joists are manufactured in a controlled environment, which reduces waste and variability in the product. This leads to more cost-effective production and better value for the end-user.

  5. Energy efficiency: I-joists have a larger depth-to-width ratio than timber joists, which allows for more insulation to be used in the cavity between the joists. This results in improved energy efficiency and a more comfortable living space.

What makes Steico I joists better at controlling hot and cold conditions?

Steico i-joists can contribute to improved hot and cold conditions in a building due to several factors:

  • Increased insulation capacity: The larger depth-to-width ratio of Steico i-joists allows for more insulation to be used in the cavity between the joists. This results in improved insulation performance and better control of hot and cold conditions.

  • Consistent support: The engineered web in Steico i joists provides uniform and consistent support, reducing the risk of thermal bridging that can occur with traditional timber joists.

  • Improved air sealing: Steico i joists can be designed to allow for improved air sealing in the cavity between the joists, reducing drafts and improving the overall comfort of the building.

It’s important to consult a professional engineer or a contractor to determine the best insulation and air sealing solution for your specific needs, and to ensure that the i joists are installed correctly.

What’s the best use for Steico I joists?

Steico i-joists can be used in a variety of building applications, including:

  1. Residential construction: Steico i-joists are commonly used in residential construction, such as floor systems, roofs, and walls.

  2. Commercial construction: Steico I joists can also be used in commercial construction projects, such as office buildings, hotels, and multi-story structures.

  3. Remodeling: Steico I joists are suitable for use in remodeling projects, as they can be easily installed in existing structures without disturbing the existing structure.

  4. Floor systems: Steico i joists are well-suited for use in floor systems, as they offer a strong, lightweight, and stable solution for spanning long distances.

It’s important to consult a professional engineer to determine the appropriate type of i-joist for a specific application and to ensure that the i-joists are installed correctly.
