Attic insulation services by Klaus Larsen Roofing

In New England's four-season climate, quality insulation is essential. It slows the transfer of heat-keeping warm air inside during freezing winters, and blocking heat during hot, humid summers. Our professionals will help you choose the right attic insulation materials and R-values based on your home's age, layout, and current insulation.

  • Cellulose Insulation: Our top choice for most attic insulation projects, blown-in cellulose creates a dense thermal blanket that's perfect for retrofits and older homes. It blocks heat loss and helps reduce ice dam formation caused by attic heat leaks.
  • Rigid Foam Insulation: Commonly installed on attic hatches, walls, or sloped ceilings, rigid foam provides high R-value and moisture resistance-great for humid summers in coastal Rhode Island or snowy winters in central Connecticut.
  • Radiant Barriers: Reflect radiant heat away from your attic to keep upstairs rooms cooler.
  • Air Sealing: Air leaks in your attic can let warm, moist air into the space, leading to mold growth and roof damage. We seal around plumbing, lighting, and framing to protect your attic and maintain energy efficiency.
  • Duct Sealing & Insulation: Ducts running through your attic? We seal and insulate them to stop energy waste-especially important in older homes where ductwork may be exposed.
