POSI JOIST
WHAT IS POSI JOIST CONSTRUCTION?
Posi-Joist offers many benefits that make it an attractive option for builders and homeowners looking for a strong, reliable, and efficient floor joist system.
Posi-Joist is a type of engineered timber floor joist system that combines the benefits of I-joists and open web joists. It is a product of the UK-based company, MiTek Industries.
Posi-Joists are designed with a top and bottom chord, and a series of timber web members in between. The timber webs are arranged in a diagonal pattern, creating an open web structure that allows for easy installation of services such as wiring, plumbing, and ductwork.
The Posi-Joist allows a variety of internal room layouts within an external shell due to its clear spanning capabilities. Exceptional floor performance from a minimum 72mm wide fixing surface makes the flooring easy, controls shrinkage, and with precision engineering, it all reduces those tiresome return visits and remedial work.
The combination of solid timber chords and the open web structure results in a stronger, stiffer, and lighter joist than traditional solid timber joists. This makes it easier to handle and install, and allows for longer spans between supports. Additionally, Posi-Joists can be designed to include insulation and acoustic properties.
Posi-Joists are commonly used in residential and commercial construction for floors, roofs, and walls.
WHAT ARE THE BENEFITS OF POSI JOIST CONSTRUCTION?
Posi-Joist offers several advantages over traditional solid timber joists, which make it a popular choice for floor, roof, and wall construction. Some of the key advantages of Posi-Joist include:
Longer spans: Posi-Joists can span longer distances than solid timber joists, which reduces the need for intermediate supports, resulting in a more open floor plan and increased design flexibility.
Increased design flexibility: The open web design of Posi-Joist allows for easy installation of services, such as plumbing, electrical wiring, and ductwork, without the need for drilling or notching holes in the joists. This results in increased design flexibility and can save time and money during the construction process.
Improved insulation: Posi-Joists can be designed to incorporate insulation between the webs, which improves thermal efficiency and can reduce energy bills.
Reduced shrinkage and warping: The use of engineered timber in Posi-Joists reduces the risk of shrinkage and warping that can occur with traditional solid timber joists, resulting in a more stable and reliable floor structure.
Reduced material usage: The open web design of Posi-Joist allows for more efficient use of materials, resulting in less waste and lower costs.
Sustainable and environmentally friendly: The use of engineered timber in Posi-Joists is more sustainable and environmentally friendly than the use of solid timber joists, as it reduces the demand for old-growth timber and minimizes waste during production.
Easier installation: Posi-Joists are lightweight and easy to handle, making them easier to install compared to traditional solid timber joists.
