A comfortable home starts with proper insulation.

Residential / Home energy upgrades / Attic insulation

Let’s talk about your home’s “thermal envelope.” It’s the barrier between the heated and cooled interior and the outside, and attic insulation plays a huge part in how it’s functioning.

Why attic insulation helps your home.

Proper insulation slows heat loss and gain, helps conserve energy, reduces utility bills, and improves temperature control and comfort.

Plus, adding proper insulation could save you up to 20% on energy bills.

R-values: what they mean & why they matter.

Insulation is measured by R-values, which indicate the insulation’s ability to resist heat flow. The higher the R-value, the better the performance. Most attics should be insulated to about R-38 when it comes to the attic floor, R-18 in the kneewalls, and R-10 in the attic access point.

Getting a head start at home? Check out these tips.

  • Remove items stored in the attic, seal any air, water, or vent leaks and repair any ceiling problems before adding insulation.
  • If your home has an attached garage or gas appliances, install a carbon monoxide monitor for safety.
  • Use the right insulation in the right areas (like dense-pack insulation for decked attic floors), level out loose-pack insulation, and install depth markers every 300 square feet.
  • Make sure there’s at least three inches clearance for any lighting not rated for contact with insulation, wiring or combustion vents.
  • Seal any ducts and insulate them to R-8.
  • Install ventilation (not powered) to remove heat and moisture from the attic, and always vent range hoods, clothes dryers and bathroom exhaust fans outside the thermal envelope.
