Knauf EcoBatt R-30: Right-Sized for Coastal LA Attics
Not every attic needs R-38. In California’s coastal climate zone 6 — Santa Monica, Venice, Manhattan, Hermosa and Redondo Beach, and much of the Westside — Title 24 sets R-30 as the prescriptive ceiling value for new homes. Knauf EcoBatt R-30 gets you there in a batt about 10 inches thick, with Knauf’s plant-based ECOSE binder instead of phenol formaldehyde and GREENGUARD Gold certification for indoor air quality.

Installation Tips
- Kraft facing faces the living space and must not be left exposed.
- Use unfaced batts, not faced, when adding over existing insulation.
- Keep soffit vents clear with baffles; keep clearance at non-IC recessed lights.
