Coronado takes the strongest salt exposure in the county , the island microclimate runs cooler and damper year-round with marine humidity that migrates through every unsealed chase.

Is mineral wool worth the extra cost?
For sound walls, fire-rated assemblies, and exterior cavities prone to moisture, yes. For typical interior walls and ceilings, fiberglass is fine and saves about a third per square foot. We will tell you where each one earns its keep.
How do you handle wires and outlets?
We split the batt around wires and slit it to fit behind outlet boxes. Compressing a batt around a wire kills its R-value at the spot you most need it (right next to a hole in the wall).
