Insulation Contractor in Albuquerque, NM

R-value measures thermal resistance: the higher the number, the better the insulation slows heat transfer. In Albuquerque's Climate Zone 4B, the DOE recommends R-49 to R-60 in attics and R-13 to R-15 in walls. Most older homes in the metro fall short of those targets, which is why an inspection and upgrade often pays back quickly in reduced utility bills.

Yes, always. Insulation slows heat transfer, but if air can still move freely through gaps around light fixtures, plumbing penetrations, and attic bypasses, you are losing a significant portion of your efficiency gains. Air sealing paired with insulation is the most cost-effective energy upgrade most homes can make.

Because Albuquerque has both hot summers and cold winters (Climate Zone 4B), the attic is the highest-priority upgrade. R-49 or higher in the attic addresses both heating and cooling loads. Air sealing is next, as Albuquerque's dry air and wide temperature swings drive significant infiltration through gaps. For walls, spray foam or dense-pack cellulose retrofit are the most effective options for existing homes.

It depends on the application. For attic roof decks, rim joists, and crawl spaces where you want a combined air seal and vapor barrier, spray foam often outperforms batts by enough to justify the cost. For standard wall cavities in new construction, batts or dense-pack cellulose are often a better value. We will give you a straightforward comparison for your specific project.
