Heat loss happens throughout the home, but common problem areas include:
Attics and attic hatches
Rim joists
Exterior walls
Windows and doors
Basement walls
Plumbing and electrical penetrations
These are often the first places professionals inspect when improving energy efficiency.

Insulation isn't just about filling wall cavities. One contractor may simply install insulation, while another also includes air sealing, proper vapor control, ventilation improvements, moisture management, and attention to detail that dramatically improves performance. Some low-priced contractors skip these critical steps to save time and money. Compare what's included, not just the final price.

No. Spray foam is an excellent air-sealing product and works well in certain applications, but it isn't automatically the best choice everywhere. Fiberglass, stone wool, rigid foam, cellulose, and spray foam each have advantages depending on the location, moisture conditions, budget, soundproofing needs, and desired performance.
-
In many homes, yes. Proper insulation combined with effective air sealing reduces heating and cooling losses, making your home more comfortable while helping your HVAC system work less. The result is often lower utility costs, fewer drafts, more consistent temperatures, and a home that's quieter and more durable over the long term.
-
Neither—they work best together. Insulation slows heat transfer, while air sealing stops unwanted airflow. Even the best insulation can't perform properly if outside air is constantly leaking around it. If you only do one, you're leaving performance on the table.
-
Both are excellent insulation products, but they have different strengths. ROXUL ComfortBatt® is a stone wool insulation that offers exceptional fire resistance, sound absorption, and water repellency. Owens Corning Next Gen™ PINK fiberglass is softer to handle, easier to install, provides excellent thermal performance, and is often more budget-friendly. The best choice depends on your project's goals.
-
Not necessarily. Drafts are usually caused by air leaks, not a lack of insulation. Sealing gaps around windows, doors, plumbing, wiring, attic penetrations, and framing often makes a bigger difference in comfort than simply adding more insulation.
-
Adding insulation beyond recommended levels usually provides diminishing returns, but poor installation can reduce its effectiveness. Compressed insulation, gaps, or missing air sealing can significantly reduce performance regardless of how much insulation is installed.
