The foundation of every Hapi Home is a cold-formed steel frame, utilizing 3.5″ 18-gauge steel studs that are precision-cut and preassembled for structural integrity. Unlike wood, steel is non-combustible, resistant to pests, and impervious to rot and mold—ensuring durability in both fire-prone and high-humidity environments.
Each home is delivered with pre-assembled floor joists, wall panels, and roof trusses, along with all necessary fasteners and connectors, optimizing build efficiency while maintaining superior structural performance.
Exterior protection against fire hazards
Our exterior envelope is designed to minimize fire risk while maximizing performance:
Roof System:
Class A-rated standing seam metal panels provide industry-leading resistance to flame spread.
A fire-resistant underlayment adds an extra layer of protection against heat and embers.
Unlike traditional eaves, our flush roof design prevents ember accumulation and reduces ignition points.
Wall Cladding Options:
Smooth-coated steel panels and fiber cement lap siding—both certified to FM 4880 Class 1, ensuring exceptional fire resistance in real-world fire exposure scenarios.
One-hour fire-rated wall assembly, providing additional protection where required by code.
Windows & Doors:
Tempered dual-pane glass with metal cladding withstands high temperatures and resists breakage under extreme heat exposure.
A fire-resistant home is only part of the solution. Our team works with clients to integrate fire-smart landscaping, deck materials, and site planning to align with the latest best practices in fire safety.
Combining cutting-edge materials, forward-thinking design, and rigorous fire-resistant construction methods, Hapi Homes delivers durable, high-performance homes that withstand fire risks while offering modern comfort and efficiency.
Enhanced safety from the inside out
Beyond the exterior, fire resistance extends to every layer of our homes:
Sheathing & Insulation:
ZIP System™ sheathing integrates ½” OSB panels, PU rigid insulation, and a weatherproof barrier, offering structural strength and moisture protection while meeting fire safety standards.
Fire-rated rigid and fiberglass insulation enhances containment and thermal efficiency.
Interior Surfaces:
Class A-rated (ASTM E84) drywall throughout all walls and ceilings.
DensShield® panels in bathrooms, providing moisture and fire protection in high-humidity areas.
Ventilation & air quality: designed for fire safety
Maintaining breathable air is crucial in fire-prone regions. Our HVAC system is built with multi-layer filtration and ember-resistant ventilation to ensure indoor air quality:
Exterior vents feature metal mesh screens and ember-resistant hoods, preventing airborne embers from entering the home.
MERV-13 filters capture particles as small as 0.5 microns, reducing exposure to smoke, allergens, and pollutants.
Interior-only air circulation mode allows residents to keep outdoor air out when air quality is poor, continuously filtering and purifying indoor air.
