A Proprietary Duct Protection System
A heavy-duty insulating and protective barrier, engineered to seal, shield, and reinforce attic ductwork against extreme Arizona attic conditions — so the cool air you pay for actually reaches your rooms.

Arizona Attics Are Brutal on Standard Ductwork
Most Southwest homes are built slab-on-grade, so the duct system lives in the attic — the hottest, harshest part of the house. Your AC may be working hard, but if ducts are leaking, overheating, and exposed up there, the cool air you paid for may never make it to your rooms.
The result shows up downstairs: that one room that never cools off, a system that runs and runs on summer afternoons, and bills that keep climbing.
See the FixExtreme Attic Heat
During summer afternoons, exposed attic ductwork absorbs heat and forces the HVAC system to fight an uphill battle.
Duct Leakage
Leaky or poorly insulated ducts waste cooled air before it reaches the living space, making the system run longer.
Premature System Wear
When airflow is restricted or air is lost in the attic, equipment works harder than intended and may wear out faster.
Dust & Indoor Air Quality
Leaks can pull hot, dusty attic air into the system and circulate contaminants through the home.
The Proprietary Fix
One System. Three Layers of Defense.
Insulated Duct Armor™ is Knights of the Attic’s proprietary duct protection system. Applied directly to your existing attic ductwork, it seals, insulates, and protects the duct system at the source — no full duct replacement required.
-
Seals
Seals duct gaps, cracks, and vulnerable connections from the outside — slaying the leakage that wastes conditioned air and reduces HVAC efficiency.
-
Insulates
A thick insulation layer shields ducts from extreme attic temperatures, keeping air colder all summer long and reducing hot and cold rooms.
-
Reinforces
A durable protective coating wraps aging ductwork, improving long-term performance and reliability for decades to come.
Built Like Armor
What’s Inside the Armor
Every layer has a job. The duct is sealed at its gaps and connections, wrapped in a thick insulating barrier, and finished with a durable protective coating that stands up to decades of Arizona attic conditions.
- Seals vulnerable duct gaps and connections
- Adds a thick, protective insulating barrier
- Shields ductwork from extreme attic heat, significantly extending its lifespan
- Helps conditioned air reach the rooms where it belongs
What You’ll Feel at Home
Comfort You Notice. Protection You Don’t Have To Think About.
Insulated Duct Armor™ works quietly above your ceiling, every hour your system runs.
Cooler Delivered Air
Insulated, protected ducts help keep air colder on its way from the system to your registers, all summer long.
Reduced Duct Leakage
Sealing gaps and cracks from the outside keeps conditioned air in the ducts instead of losing it to the attic.
Better Room-to-Room Comfort
Properly sealed and insulated ducts help conditioned air reach the rooms that need it most — including that one stubborn room.
More Consistent Airflow
Sealed ducts can improve airflow and comfort throughout the home, so your system delivers what it was designed to.
Protection From Extreme Attic Conditions
A durable outer layer shields ductwork from the heat and wear that break down unprotected ducts.
Longer-Lasting Ductwork
Armored ducts are built to protect and preserve your duct system for the long haul — with a 50+ year lifespan.

Same attic. Very different outcomes.
This isn’t an off-the-shelf wrap or a spot repair. Insulated Duct Armor™ is a proprietary system developed by Knights of the Attic and installed only by our team — one treatment that addresses leakage, insulation, and durability together.

Insulated Duct Armor™ FAQs
Insulated Duct Armor™ is Knights of the Attic’s proprietary duct protection system. It seals duct gaps and cracks from the outside, adds a thick insulating layer that protects ducts from extreme attic temperatures, and finishes with a durable protective coating — so the cold air you paid for is delivered to each room.
In many homes, no. Insulated Duct Armor™ is applied to your existing duct system, adding a durable protective layer around aging ductwork to improve long-term performance and reliability. Our free Duct & Attic Assessment determines whether your ducts are a good candidate or whether other work is needed first.
Hot and cold rooms are often caused by leaking, poorly insulated, or heat-soaked attic ductwork. By sealing leaks and insulating the ducts, Insulated Duct Armor™ helps conditioned air reach the rooms that need it most. Because every home is different, we start with a free assessment to identify what’s actually causing your problem rooms.
Insulated Duct Armor™ is built for a 50+ year lifespan — and the work is backed by our 20-year labor workmanship warranty, far beyond the 1–2 years most contractors offer.
Installs can vary based on how extensive of a project you decided to go with. Typical installs are around 1-2 days, sometimes extending into 3 days on the larger projects. The work happens in your attic, not your living space, and our team documents the job with before, during, and after photos — then cleans up completely when we’re done.
