Our Process Advantages
A clear comparison of SUNRUN construction standards and common entry-level market practices.
| Process Area | SUNRUN Standard | Common Market Practice |
|---|---|---|
| 01Frame | Fully galvanized steel with electrostatic powder coating, reinforced lifting heads and a balanced load-bearing frame. | Black steel or partially protected frames; reinforcement and corrosion-protection details are often unclear. |
| 02Profile Density | Closer steel-member spacing provides stronger floor support, better stability and greater resistance to deformation. | Reduced steel sections or wider spacing may lower cost but can increase floor vibration and structural movement. |
| 03Embedded Hinge | Recessed galvanized hinges sit flush with the floor for a smooth surface and a cleaner finished appearance. | Exposed welded hinges may protrude above the floor and leave uneven welds or finishing gaps. |
| 04Roof Waterproofing | A 0.8 mm corrugated steel center roof supports effective drainage and more reliable long-term waterproofing. | Sheet-roof joints often rely on waterproof tape that can age, loosen or create leakage risks. |
| 05Wall Insulation | 75 mm EPS exterior walls and 50 mm interior partitions, with PU, rock-wool and other climate-specific upgrades. | Basic 50–65 mm EPS panels with fewer insulation grades and limited climate-specific options. |
| 06Windows & Glass | Thermal-break aluminum frames with double, triple, Low-E or laminated glazing and customizable sealing systems. | Standard uPVC, aluminum or single-glass systems; profile, hardware and sealing grades may be unspecified. |
| 07Electrical Wiring | Destination-standard circuits, concealed wiring, separated protection and protected folding points, factory tested. | Basic direct wiring with limited protection at folding points and incomplete circuit-sizing details. |
| 08Bottom Insulation | PU spray or EPS insulation with optional graphene floor heating forms an integrated insulation, moisture-control and heating system. | A basic floor substrate or simple EPS filling, often without a complete bottom-insulation or heating system. |
| 09Bathroom Drainage | Concealed pipework with floor slope, drainage speed and joint sealing checked before shipment. | Exposed or basic PVC drainage with limited information on slope, sealing and pre-delivery testing. |
| 10Interior Finish | Bamboo-wood fiber wall and ceiling panels with coordinated trim reduce or eliminate secondary on-site finishing. | Galvanized color-steel interiors and sealant-finished gaps provide a more basic appearance and living comfort. |
