Insulation FAQs

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.

We install spray foam (open and closed cell), blown-in cellulose and fiberglass, fiberglass and mineral wool batts, rigid foam board, and reflective radiant barriers. The right material depends on the application: spray foam is the best air barrier, cellulose dense-packs into existing walls without drywall removal, and batts work well in open cavities during construction.

Common signs include high energy bills, rooms that are hard to heat or cool, drafts near outlets and light switches, and visible thin or uneven insulation in your attic. We offer a whole-home insulation inspection that identifies gaps and ranks upgrade opportunities by payback.

Yes, though adobe and masonry homes need a different approach than wood-frame construction. Masonry walls act as thermal mass and work differently from cavity-fill insulation. Spray foam on the interior face, exterior continuous insulation, or dense-pack in any wood-framed sections are common strategies we use in Albuquerque's older adobe neighborhoods.

Open-cell foam is softer, less dense, and typically used for interior applications like wall cavities and attic floors. It has a lower R-value per inch (around R-3.7) but is excellent for air sealing and is more affordable. Closed-cell foam is denser, has a higher R-value (around R-6.5 per inch), acts as a vapor barrier, and is ideal for crawl spaces, rim joists, and roof decks where moisture resistance is important.

Yes. Spray foam off-gasses during and immediately after installation. We ask residents (including pets) to vacate for a minimum of 24 hours while the foam cures. We will confirm the specific window based on the area being sprayed, the product used, and ventilation.

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.

Results vary by home, but the EPA estimates that proper sealing and insulation can save an average of 15% on heating and cooling costs. Albuquerque homes with older or insufficient insulation often see savings at the higher end of that range given the extreme summer heat and cold winters at 5,300 feet elevation. We can walk you through a rough estimate based on your home size and current insulation condition.

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.

The federal Inflation Reduction Act allows a 30% tax credit (up to $1,200 per year) for insulation and air sealing improvements in existing homes. New Mexico also has utility rebate programs through PNM and other providers. We can give you the product documentation you need to claim credits; consult a tax professional for eligibility questions.

At 5,300 feet, the air is thinner and solar radiation is more intense than at sea level. Attic temperatures can reach 150F or higher in summer, putting far more load on cooling systems than lower-elevation cities with similar air temperatures. Proper attic insulation and a radiant barrier dramatically reduce that heat transfer into your living space.

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.

Yes. Spray polyurethane foam (SPF) roofing is particularly well-suited to Albuquerque's climate because it provides both insulation and a seamless waterproof surface in one system. The high UV exposure here does require an elastomeric topcoat with UV protection, which we apply as part of every foam roof installation. Properly maintained foam roofs can last 20 to 25 years.
