Air leaks at top plates and rim joists
Why it happens here
Wind exposure on the Heights bench pushes air hard against the building envelope, and every unsealed penetration becomes a leak. Top plates, rim joists, recessed lights and outlet boxes are the usual suspects. Insulation alone does not stop air movement.
Our approach
We air-seal every penetration with low-expansion foam and insulation tape before adding any insulation. Then we verify the work with a thermal imaging camera. Sealing first is the difference between a real fix and a cosmetic one.
