The Issue: Where Insulation Stops, Thermal Performance Drops

Even well-insulated roofs can lose thermal performance at the edge — where traditional wood nailers stop insulation 6–8" short of the perimeter.

That gap interrupts full coverage, leaving a consistent point for energy loss. And the results are visible: just look at the bright yellow-orange of the thermal scan in the header above (taken from a real-world project).

This becomes a predictable weakness — thermal modeling confirms it.

The simulation of a traditional wood nailer detail below on the left shows a wide temperature gradient at the edge, clear evidence of energy loss caused by interrupted insulation. That kind of loss adds up.

Here’s the Fix: Wood Nailer Alternatives

Eliminailer-T and EdgeBox RI — metal alternatives to wood nailers — allow insulation to extend fully to the edge.

No break. No disruptions. Just full coverage — and it works. 

The companion simulation above on the right proves it: with Eliminailer-T in place, edge temperatures stay tighter and more consistent, effectively reducing energy loss at one of the system’s most overlooked details.
