Benefits of Träframe Posi-Joists

Posi-Joists are fast becoming the preferred choice for floor joists over traditional solid timber options & it’s easy to see why.

• Long spans & Strong Structural Performance. Posi‑Joists are engineered to span significantly greater distances than traditional solid timber joists, occasionally reducing the need for intermediate supports and allowing more flexible internal layouts & roof applications alike.

• Open Web Design for Service Installation. The open web structure allows for simple & fast installation for pipes, cabling and services, reducing labour costs on site.

• Lightweight & easy to handle On-Site. Posi Joists are significantly lighter than traditional timber joists, as they use less material without compromising on strength. All joists are engineered in our factory to site dimensions, and their precision manufacturing & straightness reduces site adjustments and remedial works.

• Sustainable & Efficient Use of Materials. Our state-of-the-art design software and factory machinery ensures efficient use of materials, generating less waste & reducing environmental impact compared to traditional solid timber joists.

• Insulation & Acoustic Performance. The open web design allows plenty of space for installing insulation which improves thermal performance in floors & roofs. They can offer better sound absorption & future squeaking in minimised compared to solid joists.
