Fiberglass batts are the most widely used insulation product in residential construction. Available in R-13 (2x4 walls), R-15, R-19, R-21 (2x6 walls), and R-30 (floor/ceiling), fiberglass batts are a cost-effective option when framing is open and air sealing is addressed separately.
Smooth installs fiberglass batts in new construction, gut-rehab, and addition projects throughout Boston and all of New England. We always complete thorough air sealing before batt installation — the critical step that most contractors skip, and the primary reason batts underperform their rated R-value in practice.
