Frequently Asked Questions About Insulation
Insulation helps regulate your home’s temperature—keeping it warm in winter and cool in summer. It also reduces energy bills and even muffles unwanted noise. Think of it as your home’s year-round comfort coat.
Not always. If it’s clean, dry, and still fluffy, it can stay. But if it’s damp, moldy, or full of critter droppings, it’s time to replace it.
Dirty insulation usually means air leaks. Dust gets pulled in through gaps in your attic. Insulation acts like a filter; if it’s dirty, it’s telling you exactly where your home is losing efficiency.
R-value measures how well insulation resists heat flow. The higher the R-value, the better it insulates. Think of it like a GPA for your attic; higher is usually better, but balance matters.
Air sealing plugs all the little leaks that let outside air in and conditioned air out. It boosts your insulation’s performance and helps keep your home more comfortable and energy efficient.
Heat rises, and if your attic isn’t sealed or insulated properly, that hot air will linger. Insufficient insulation, poor airflow, and overworked HVAC systems all make upstairs spaces harder to cool.
On mild days, it should cycle occasionally. If it’s running nonstop, your home may have poor insulation or air leaks, or someone left a window open again.
Common types include fiberglass batts, spray foam (open and closed-cell), cellulose, mineral wool, and rigid foam boards. The right type depends on your home and goals.
Open-cell is soft, flexible, and great for soundproofing. Closed-cell is rigid, creates a moisture barrier, and provides a higher R-value, but needs to be carefully installed to avoid trapping moisture.
Yes. Insulation slows sound transmission. Spray foam, cellulose, and mineral wool are especially good at reducing noise between rooms or from outside.
Absolutely. Proper insulation and air sealing reduce condensation, which lowers the risk of mold growth behind drywall or in your attic.
Fiberglass and cellulose can last 50+ years. Spray foam often lasts the life of your home when installed correctly by professionals.
Yes, when installed by trained professionals. Spray foam is highly effective but needs precise handling due to its chemical makeup and moisture sensitivity.
