Ducting
Solutions
The backbone of every HVAC system. Properly sized and sealed ductwork keeps your home comfortable and your energy bills low — and Xpress installs it right the first time.
R-8 Flex Duct
R-8 flexible duct is the most widely used residential ducting solution in the Greater Houston area — and for good reason. Its pre-insulated, double-layer construction meets and exceeds Texas energy code requirements, while its flexibility makes it ideal for navigating the tight attic spaces and complex framing found in most Houston-area homes.
Unlike older R-6 flex duct, R-8 provides significantly better thermal performance, reducing heat gain in hot attics and keeping conditioned air at the right temperature all the way to your vents.
- R-8 insulation rating — exceeds Texas energy code requirements
- Flexible routing around framing, joists, and attic obstacles
- Pre-insulated from the factory — no extra wrap needed
- Lightweight and fast to install — lower labor cost
- Ideal for residential attic and crawlspace runs
- Available in standard diameters from 4" to 20"
Best For
Residential Replacements
Perfect for swapping out old, deteriorated flex duct in existing homes.
Attic & Crawlspace Runs
Navigates tight spaces and irregular framing with ease.
Budget-Conscious Upgrades
Lower material and labor cost without sacrificing performance.
Houston's Hot Climate
R-8 rating minimizes heat gain in scorching Texas attics.
Best For
New Construction
Designed and fabricated to spec during the build phase for a perfect fit.
Commercial Applications
Required by code for many commercial and light industrial HVAC systems.
High-Static Systems
Handles high airflow demands without restriction or deformation.
Long Straight Runs
Zero sag or compression means consistent airflow over long distances.
Sheet Metal Duct
Sheet metal ductwork is the gold standard for HVAC air distribution — custom fabricated from galvanized steel to the exact dimensions of your system. Unlike flex duct, sheet metal maintains its shape permanently, delivering consistent, unrestricted airflow from the air handler to every register in the building.
When properly sealed with mastic or foil tape, sheet metal ducts are virtually airtight, maximizing system efficiency and preventing the conditioned air losses that drive up energy bills. It's the preferred choice for new construction, commercial builds, and any high-performance residential system.

- Maximum airflow efficiency — no compression or sag
- Superior air sealing with mastic or foil tape
- Extremely long lifespan — outlasts the HVAC equipment
- Ideal for long straight runs and high-static systems
- Required for many commercial and new construction builds
