Insulation Contractors Providing Services Throughout Ocala & Marion County

Cellulose is hygroscopic and draws in ambient moisture, which adds weight and drives settling over time. Fiberglass does not absorb water into the fiber itself, so installed depth stays closer to what was measured on day one.

Closed-cell cures with sealed cells that block bulk water and slow vapor diffusion through the assembly. Open-cell cures with interconnected cells that remain permeable, which is why it belongs on the conditioned side rather than against a moisture source.

No, it works on radiant transfer while R-value measures conductive resistance, so the two are not interchangeable. A reflective deck coating reduces the radiant load reaching the insulation rather than adding to the insulation itself.

Steel conducts heat almost immediately and offers no thermal lag, so the assembly needs to be sealed at the panel rather than insulated beneath it. Foam applied directly to the deck also closes the seams where warm humid air would otherwise condense against the cold steel.

Someone gets into the attic, measures existing depth, and checks the areas you cannot see from the hatch. You get a scope and a number from what was measured, not from a guess at your square footage.

Any month works, though crews move faster in cooler weather and attic conditions are easier on everyone. Waiting through a Florida summer with thin coverage costs more than scheduling it does.

The shape of the cavity and whether moisture reaches it. Open framing takes batt, irregular or vaulted space takes open-cell, and anything facing humidity or bare steel takes closed-cell.
