The balance between predictable floor performance and costs.

Every new homeowner wants a floor that feels solid underfoot. The TJ-Pro Ratings System gives you the best method for delivering predictable floor performance. The TJ-Pro Ratings system allows builders to dial in floor feel by evaluating the combined effects of TJI® joists, spacing, floor decking, and the method of attachment, leading to a floor that feels perfect to each homeowner.

Floors built using the TJ-Pro Ratings System can meet or exceed your buyer's expectations and actually cost less than what you've been building. That's because TJ-Pro Ratings analyzes every TJI joist and panel in the structure to achieve the desired performance with the most efficient use of material. Once you find that balance, the TJ-Pro Ratings System can be applied to all of your house plans to ensure predictable results every time. With TJ Pro Ratings, you're in charge and can adjust any component spec to move the rating needle up or down to deliver better performance or cost-efficiency, whatever the situation or the customer calls for.

How it Works


TJ-Pro™ Ratings take the guesswork out of achieving an ideal balance between performance and cost. It automatically calculates every performance factor—including TJI® joist depth, span, spacing, and the type and thickness of the subfloor—to determine the materials you need and help maintain your budget.
