Spray foam, fiberglass batts, cellulose, and rigid foam boards are common options. Spray foam offers high thermal resistance and air sealing in one application.
Spray foam provides better air sealing, higher R-values per inch, and improved moisture resistance. Fiberglass is less expensive but does not provide an air barrier.
It reduces energy loss, improves indoor air quality, minimizes drafts, and can strengthen walls. It also prevents moisture buildup and mold growth.
Properly installed spray foam can last over 30 years without significant degradation. It does not sag or settle like other insulation types.
Once cured, spray foam is non-toxic and inert. Installation should be done by professionals, and occupants should avoid the area for 24 hours after application.
Yes, spray foam and blown-in insulation can be installed in existing walls through small access holes. The process requires minimal disruption.
Yes, spray foam and cellulose provide good sound dampening by sealing gaps and absorbing sound. Fiberglass offers limited sound control.
Signs include uneven temperatures, high energy bills, cold drafts, and frequent HVAC cycling. An energy audit can provide a precise assessment.
Costs vary based on home size, insulation type, and accessibility. Spray foam typically ranges from $1.00 to $3.00 per square foot installed.
Most residential insulation projects take 1 to 2 days. Larger homes or complex areas may take longer.
R-value measures insulation's resistance to heat flow. Higher R-values mean better thermal performance, which helps maintain indoor comfort.
No routine maintenance is needed. It's durable and resistant to pests, moisture, and decay. Damaged sections should be inspected and repaired if needed.
Most insulation materials, including spray foam, meet fire safety codes and are treated with fire retardants. Always follow local building codes.
Yes, properly installed insulation reduces heating and cooling demands, which can lower energy bills by 15% or more depending on the home.
State and federal programs may offer rebates or credits for energy-efficient upgrades. Check current local incentives for eligibility.
Yes, spray foam can be applied over or under existing insulation if it is dry and in good condition. A professional inspection can confirm suitability.
Key areas include attics, walls, crawl spaces, rim joists, basements, and around ducts or plumbing. Sealing gaps is also important.
