Home Features & Building Technology
Every Affordable Home US property includes a suite of advanced building technologies designed for durability, energy efficiency, and safety in the Alabama climate.
Superior Storm Resistance
EcoPanels SIPs construction creates a continuous structural envelope that outperforms traditional wood framing in high-wind events. Independently tested to ASTM-E72 standards and documented in real-world tornado events.
Waterproof Roofing Membrane
Every production home includes a waterproof roofing underlayment membrane that protects the structure even if surface roofing is damaged in a storm. This is a standard feature — not an upgrade.
Radiant Barrier Technology
Reflective radiant barrier insulation reduces summer heat gain significantly, lowering cooling loads and utility bills in Alabama's hot climate.
Air-Sealed Duct System
All ductwork is fully sealed and pressure-tested to eliminate conditioned air loss — a major source of energy waste in conventional construction.
Zip System Sheathing
Structural wall sheathing with an integrated water-resistive barrier eliminates the need for house wrap and provides a tighter building envelope.
Crawlspace Foundation
Homes are built on a sealed, conditioned crawlspace foundation with moisture barriers and proper drainage — protecting the structure from ground moisture common in Alabama.
Optional Upgrade: Tornado-Proof Safe Room
A steel-reinforced in-home safe room rated for EF5 tornado winds is available as an optional upgrade on any home.
