MTZ Insulation LLC: Your Local Attic Insulation Experts

Is your home struggling to stay comfortable through Denver's extreme seasons? The solution might be right above your head. At MTZ Insulation, we've helped hundreds of Denver homeowners solve their comfort problems and cut energy bills with proper attic insulation.

Understanding Denver's Unique Climate Challenges

Denver's climate presents special challenges for homeowners. Sitting at the "Mile High" elevation, our homes face weather conditions that much of the country doesn't experience:


Intense sun exposure - Denver gets over 300 sunny days per year, far more than the national average. This sunshine beats directly on your roof, heating your attic to extreme temperatures in summer.

Dramatic temperature swings - We often see 30-40 degree temperature changes in a single day. Your home's insulation needs to handle both freezing mornings and hot afternoons.

Dry, thin air - Our high altitude means air holds less moisture and heat, making proper insulation even more important for maintaining indoor comfort.

Cold winter nights - While our winter days can be mild, nighttime temperatures regularly drop below freezing from November through March.

These unique conditions mean Denver homes need specialized attic insulation solutions—not just standard approaches that work elsewhere.

Signs Your Denver Home Needs Better Attic Insulation

Many Denver homeowners don't realize they have an insulation problem until we point it out. Here are common signs we see across Aurora, Lakewood, Westminster and other metro areas:

  • Your second floor feels much hotter than your first floor in summer
  • You notice ice dams forming on your roof edges in winter
  • Some rooms in your home are always too hot or too cold
  • Your heating and cooling bills seem unusually high
  • Snow melts faster on your roof than on your neighbors' homes

If you're nodding your head to any of these, your attic insulation is likely inadequate for Denver's unique conditions.

The MTZ Insulation Approach to Denver Attics

At MTZ Insulation, we don't believe in one-size-fits-all solutions. Homes in Denver Heights face different challenges than those in Highlands Ranch or Golden. That's why our process includes:

Thorough attic inspection

 We check your existing insulation, look for air leaks, assess ventilation, and identify any moisture issues.

Custom insulation plan

Based on your home's specific needs, we recommend the right type and amount of insulation for Denver's climate.

Professional installation

Our trained teams properly seal air leaks first (a step many competitors skip), then install insulation to the proper depth.

Final quality check

We verify that all areas are properly covered and that your attic ventilation is working correctly with the new insulation.

Types of Attic Insulation for Denver Homes

We offer several insulation options, each with benefits for different Denver-area homes:

Blown-in fiberglass

Great for most Denver homes, providing excellent coverage in attics with irregular spaces.

Batt insulation

Sometimes the right choice for new construction or attics with standard joist spacing.

Spray foam

Perfect for sealing hard-to-reach areas in older Englewood and Littleton homes with complex roof structures.

Radiant barriers

An additional option for homes in sunny parts of Centennial and Parker that face extreme summer heat.

We'll help you understand which option makes the most sense for your specific home and budget.
