Delta Attic Performance System
Your home isn’t just hot, it’s being heated from above.
Most Arizona homes don’t have an insulation problem — they have an attic heat problem. Adding more insulation alone won’t fix it. The real solution starts with controlling where the heat comes from.

In Phoenix, your attic can reach 160°F on a summer afternoon — and that heat doesn’t stay up there. It radiates through your ceiling, forces your AC to work harder, and drives up your electric bill all season long. Delta’s Attic Performance System is a multi-layer approach that addresses all three ways attic heat enters your home: radiant heat from the sun, convective heat in superheated attic air, and conductive heat that transfers through your ceiling overnight. It’s a complete attic solution that addresses the root cause instead of just adding more insulation.
Most attics don’t have an insulation problem — they have a heat problem.
More insulation alone is like adding more buckets to a leaky roof.
3 Ways Heat Gets Into Your Home
A real solution has to address all three — because fixing only one leaves the other two working against your comfort and your A/C.
Problem 1
Radiation
The sun hammers your roof all day. That energy radiates directly into your attic as infrared heat — super-charging the air inside and baking everything it touches
Problem 2
Convection
Once that radiant heat builds up, the air in your attic becomes a superheated oven. It circulates and rises — cooking your insulation and your ductwork from outside in.
Problem 3
Conduction
Even after the sun goes down, heat stored in attic materials slowly transfers through your ceiling — why your home still feels warm at midnight.
Our Comprehensive Solution Includes:
RADIATION BLOCKING
- Block radiant heat before it enters the attic
- Reflect most of the radiant heat before it reaches your insulation
- Reduce the infrared heat that superheats attic air
- Help protect insulation and attic materials from extreme exposure
- Solution: Radiant Barrier
PERFORMANCE OPTIMIZATION
- Remove built-up attic heat with active ventilation
- Move hot attic air out before it builds up
- Use solar-powered performance that works hardest on the hottest days
- Reduce heat buildup around ductwork and insulation
- Solution: Solar Attic Fan
EFFICIENCY IMPROVEMENTS
- Slow remaining heat transfer through the ceiling
- Improve the effectiveness of the insulation already working in the system
- Reduce the amount of stored heat entering the home after sunset
- Support more stable indoor comfort and less A/C strain
- Solution: Upgraded Insulation
We Don’t Just Add Insulation.
We Control the Heat.
Block It
Stop Radiation First
A radiant barrier reflects most of the radiant heat before it reaches your insulation.
Product: Radiant Barrier
Remove It
Actively Exhaust Heat
A solar attic fan moves hot attic air out before it builds up.
Product: Solar Attic Fan
Slow It
Resist What Remains
With radiant heat blocked and convective heat flushed out, your insulation only has to resist a fraction of its original load — making it dramatically more effective.

Your Home Is Unique.
So Is Our Recommendation.
Every attic is different. The right insulation level for your home depends on what’s already there, how your attic is ventilated, and the specific heat load your home carries.
We don’t sell a one-size-fits-all package. We assess your attic, look at existing conditions, and recommend the R-value that makes the most sense for your specific home — then show you the full range of options clearly.
1
Free Attic Assessment
- Inspect current insulation levels and overall attic condition
- Evaluate attic ventilation and heat buildup patterns
- Identify problem areas affecting comfort and A/C performance
- Measure the attic’s current heat load and system demands
- Note any damage, contamination, or removal needs
2
Honest Recommendation
- Recommend the right R-value based on your home’s conditions
- Explain whether R-30, R-38, or R-49 makes the most sense
- Show clear package options with no pressure
- Walk you through the full system and what’s included
- Let you choose the solution that fits your priorities and budget
3
You Choose
We present all options and let you decide what fits your priorities and budget.
- R-30 (Good): Starter level for under-insulated homes

Frequently Asked Questions — Attic Performance System Phoenix
Does adding attic insulation really make a difference in Phoenix?
Yes, but insulation alone isn’t the complete solution in Phoenix. Most Valley homes don’t have an insulation problem — they have an attic heat problem. Adding insulation without first blocking radiant heat is like adding buckets under a leaking roof. Delta’s system addresses radiant barrier, convection, and conduction together for maximum impact on comfort and energy costs.
What is a radiant barrier and how does it work?
A radiant barrier is a low-emittance, usually foil-faced material installed in an attic, often on the underside of the roof decking or rafters, with its reflective surface facing an airspace. As the sun heats the roofing and roof deck, the barrier reduces the long-wave infrared heat radiated from the hot deck toward the attic floor, insulation, and HVAC ducts.
Some aluminum radiant barriers reflect approximately 95–97% of this thermal radiation, although performance depends on the tested product, installation, airspace, cleanliness, insulation level, and attic design. In hot, sunny climates such as Phoenix, a properly installed radiant barrier can lower peak attic temperatures and reduce air-conditioning demand, particularly when ductwork is located in the attic. Field studies commonly report attic-temperature reductions in the single digits, with larger reductions possible under favorable conditions, and cooling-energy savings often in the range of roughly 4–10%.
Radiant barriers can be a cost-effective Arizona upgrade, especially when installed at low incremental cost during construction or reroofing, but their return should be compared with attic insulation, air sealing, and duct sealing for the individual home.
How much does attic insulation cost in Phoenix?
It depends on your attic’s size, how much insulation is already there, and whether you add a radiant barrier. Delta offers free attic assessments — we’ll give you an exact quote with no pressure to buy.
How much can I save on my electric bill with attic improvements?
For radiant barriers, field studies commonly report cooling-energy savings of roughly 4–10%, depending on the home, the attic design and whether the ducts run through the attic. A radiant barrier can be a cost-effective upgrade, especially when it goes in during construction or reroofing; we compare the return with insulation, air sealing and duct sealing for your home.
Does Delta also clean and seal ductwork?
No. The Attic Performance System is a radiant barrier, a solar attic fan and an insulation top-off. It doesn’t include duct cleaning or sealing.
