High-Performance Attic & Wall Insulation

Improve comfort, reduce energy waste, and lower monthly utility bills year-round.

R-Values, Requirements & Recommended Insulation Levels

Your attic and walls play a major role in how well your home holds heat during winter and stays cool throughout summer. Most Colorado homes benefit from attic insulation levels between R-49 and R-60, while wall insulation commonly ranges from R-13 to R-21 depending on framing depth and construction type. This guide helps homeowners understand insulation requirements, recommended R-values, and the best upgrade options for long-term comfort and energy savings.

Understanding R-Value

R-value measures how well insulation resists heat flow. In simple terms, the higher the R-value, the better the insulation performs. The right R-value depends on your climate, your home’s construction, and the area being insulated.

For Colorado homes, attic insulation often needs to reach higher levels than many older homes currently have. Existing homes frequently fall short of today’s recommended insulation levels, which is why upgrades can make such a noticeable difference. In Colorado’s Climate Zone 5, attic insulation minimums are commonly set at R-49, with R-60 recommended for higher elevations or more complex attic layouts.

Recommended Insulation Levels

Attic insulation:
  • Recommended: R-49 to R-60
  • Best for reducing heat loss, improving comfort, and lowering energy waste
Wall insulation:
  • Recommended levels vary by wall depth, framing, and existing construction
  • Common targets depend on whether the home is new construction, a remodel, or an insulation retrofit

What Homeowners Should Know Before Installing Insulation

Before adding new insulation, it is important to check:

  • Existing insulation depth and condition
  • Air leaks around top plates, fixtures, and penetrations
  • Wall cavities and framing depth
  • Moisture or pest-related damage
  • Areas where insulation has settled, compressed, or fallen out of place

In many homes, insulation performs best when paired with proper air sealing. That helps prevent conditioned air from escaping before the new insulation can do its job.

Best Options for Attic & Wall Insulation

For most homes, the best solution depends on the space being insulated and the current condition of the home. Common options include:

  • Blown-in insulation for attic upgrades and existing spaces
  • Batt insulation for open wall cavities and new construction
  • Spray foam for areas that need added air sealing or higher performance in tighter spaces

The right choice depends on your structure, budget, and efficiency goals.

Signs You May Need More Insulation

You may need an upgrade if you notice:

  • Uneven room temperatures
  • Drafts or cold spots
  • High heating and cooling bills
  • Rooms that are hard to keep comfortable
  • Heat buildup in the attic
  • Older insulation that looks thin, damaged, or compressed
