Batt and blown fiberglass insulation for walls, ceilings and attics.
Fiberglass Insulation: Batts and Blown
Fiberglass is still the most installed insulation in the country. It is economical, it is non combustible, it gives pests nothing to eat, and installed correctly it performs to its rating. That last condition carries a lot of weight.
Spray Foam Insulation Phoenix installs fiberglass as batts and rolls in framed cavities, and as blown loose fill in attics and enclosed cavities.
When Fiberglass Is the Right Specification
When the cavity is regular and fully accessible, when budget is a real constraint, and when the assembly does not need air sealing built into the insulation itself. A standard vented attic floor over a house whose ducts are not in the attic is the textbook case.
It is the wrong specification when the actual problem is air movement. Fiberglass slows conducted heat but air passes through it freely. If the assembly leaks, fiberglass alone will not fix that, and this accounts for a large share of insulation jobs that disappoint the customer.
Installation Quality Decides the Outcome
A batt compressed to fit, cut short, or crammed around wiring loses a real part of its rated performance. Edge gaps matter more than most people expect. Blown material has to reach a consistent verified depth across the entire area, including the awkward run near the eaves.
We install to rated depth across the full area, cut batts to fit rather than compressing them, and split them around obstructions instead of forcing them past. Unspectacular work, and it is the whole difference between the rating on the bag and the performance in the building.
The Hybrid Approach
Fiberglass and foam are not competitors. A common and cost effective specification is to foam the penetrations and the top plate line for air control, then blow fiberglass over it for bulk thermal resistance at a lower cost per inch.
