Thermal bridging / Discussions

The builder on this 15 year old home ran the heat runs in the exterior joist space, he then insulated against the rim joist and under the heat runs, then wrapped from the mud sill to the underside of the plywood on the interior of the first joist and sealed the poly to the plywood with acoustical caulk, we will now spr...

Hi Tom, 2x4s can be used for homes no problem, but it definitely fattens up the posts required between windows. The sections of wall between the ...

...thermal bridging through studs in the form of frost lines.

Feel free to send us more details or pics of the wall. I a...

We have a page on how to choose the best windows and what to look for in window performance. Choosing triple pane windows instead of double ...

Albeit, the screws from the second layer of strapping do not go directly into the studs, but they still go directly into the first layer of strapping which is itself directly screwed into the studs.
