Where batts fit in Boca Raton
For open framing — a Boca new build, a west-Boca addition, a garage conversion, or interior partition walls — batts are fast, clean, and easy to inspect before drywall. In Boca's many two-story homes they also add valuable sound control between floors and bedrooms.
Installation is everything
Batt R-value only shows up when the install is right. Gaps and compression around wiring and outlets leave thermal holes. Our crews split batts around wires, fill corners fully, and avoid compression so you get the rated number, not a paper one.
Faced or unfaced on the coast?
In Boca's hot-humid, cooling-dominated zone 1A climate the vapor-retarder choice matters — the wrong facing can trap moisture in a wall. We specify the correct assembly for your wall type and exposure.
