Insulation

Material installed in your walls, attic, floors, and crawlspace that slows heat transfer, keeping warm air in during winter and hot air out during summer.

What Is a Insulation?


Insulation is measured in R-value — the higher the R-value, the better it resists heat flow. Common types include fiberglass batts, blown cellulose, spray foam, and rigid foam board. Different areas of your home need different R-values: Oregon recommends R-49 for attics, R-21 for exterior walls, and R-30 for floors over unconditioned spaces. Older Southern Oregon homes are often significantly under-insulated by modern standards, forcing HVAC systems to work much harder than necessary.

Why It Matters for Your Home

Insulation and your HVAC system are partners. Upgrading your HVAC without addressing inadequate insulation is like putting a new engine in a car with bald tires — you won't get the performance you're paying for. Improving insulation can actually allow you to install a smaller, less expensive HVAC system while achieving better comfort. Always evaluate insulation as part of any major HVAC project.
