While 2 inches doesn’t seem like a lot for the average guy, you will find that 2 extra inches on our ThermaGuard product is, in fact, a lot. It’s the difference between needing to pull up the second sheet underlap to staple your next run of insulation, and just being able to run your next run without thinking about it.
It could also prevent the need to run a small strip at the end when running vertically across a building depending on how much was overlapped.
When running horizontally, it provides the little extra needed to span the lathing when the runs vary a little bit.
When butting the edges together, make sure to use a high quality reflective tape.
