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. |

Frequently Asked Questions
Can the F700 layout be customized?
Yes. Room arrangement, doors, windows, kitchen, bathroom, electrical and plumbing positions can be adjusted within the structural design limits.
Can the insulation be upgraded for cold climates?
Yes. PU insulation, thermal-break aluminum windows, insulated or Low-E glazing and electric floor heating can be specified for the project climate.
Is the house delivered finished?
The selected configuration can be factory-finished with interior wall and ceiling panels, electrical preparation, plumbing, kitchen and bathroom components to reduce on-site work.
Can SUNRUN provide a solar power system?
Yes. Solar panels, hybrid inverter, battery storage and project-specific cable packages can be integrated after the electrical load and destination requirements are confirmed.
How is the unit transported and installed?
The house is folded for container transport, unloaded with suitable lifting equipment and expanded on the prepared foundation. Final logistics and lifting plans are confirmed per project.
What information is needed for a quotation?
Please provide destination, quantity, intended use, preferred layout, insulation level, electrical standard, interior finish and required optional systems.
