In Colorado, attic insulation is one of the most important and overlooked parts of a home.
Most homeowners focus heavily on:
But the reality is that poor attic insulation can dramatically affect:
At Excel Roofing, we commonly recommend higher insulation values because many older Colorado homes still do not meet modern insulation recommendations.
The more properly installed insulation a home has, the less heat transfer occurs through the attic. That means the HVAC system does not have to work nearly as hard to maintain temperatures year round.
Insulation is measured using something called R-value.
R-value measures how well insulation resists heat transfer.
The higher the R-value:
For Colorado homes, modern attic insulation recommendations commonly range around:
Unfortunately, many older homes throughout Denver and the Front Range still have attic insulation levels closer to:
That means many homeowners are losing substantial energy through the attic without realizing it.
Higher attic insulation levels can help:
Colorado homes deal with:
Proper insulation helps stabilize the home year round.
For most homes in Colorado, blown-in fiberglass insulation remains one of the best overall solutions when properly installed.
It offers:
At Excel Roofing, Owens Corning insulation systems are typically our preferred choice.
Owens Corning products have built a strong reputation for:
Their attic insulation systems perform very well in Colorado’s climate conditions and integrate well with complete roofing and ventilation systems.
Owens Corning’s blown fiberglass insulation products are commonly used in both:
Johns Manville is another highly respected insulation manufacturer, especially here in Colorado.
They produce:
Their products are widely used throughout residential and commercial construction.
CertainTeed also manufactures quality fiberglass insulation systems with strong thermal performance and broad contractor use.
Knauf has gained popularity for softer fiberglass products and environmentally focused manufacturing processes.
Pricing depends heavily on:
For many Colorado homes, professional attic insulation upgrades commonly range around:
While spray foam insulation can offer strong thermal performance, it is not always our preferred recommendation for residential attic systems. One concern with spray foam is that if the roof develops a leak or moisture intrusion issue, the foam can encapsulate and hide the problem rather than allowing water to visibly travel or drain. In some situations, homeowners may not realize there is a leak until substantial wood rot or structural damage has already occurred. Because the foam adheres directly to the decking and framing, identifying and repairing hidden moisture issues can also become significantly more difficult and expensive.
For many homeowners, upgrading to a higher R-value fiberglass blown-in system provides one of the best overall returns on investment.
One of the best times to upgrade attic insulation is during a roofing project.
Most homeowners never think about combining the two, but logistically it often makes a huge amount of sense.
Because blown-in fiberglass insulation requires:
installation can become much more disruptive if crews must enter through the interior of the home.
Unfortunately, many attic accesses are located:
That means crews may need to run large hoses through the home.
During roofing projects, insulation crews can often access attic spaces more easily from the roof while portions of the roofing system are already open.
This helps:
And frankly, homeowners usually prefer avoiding the possibility of insulation equipment malfunctioning inside the home.
An insulation machine spraying fiberglass throughout a closet full of clothes is less than ideal.
Even with high insulation levels, attic ventilation remains critical.
A properly functioning attic system needs balance between:
Too much insulation without proper airflow can still create:
That is why insulation and roofing systems should always be evaluated together.
For many Colorado homeowners, attic insulation is one of the best long-term home efficiency upgrades available.
Proper attic insulation can help:
At Excel Roofing, we commonly recommend evaluating attic insulation during roofing projects because it is often the most efficient and least disruptive time to improve the entire attic system.
