Project Location: Williston, South Carolina, USA (5105 Fellowship Road, Williston, SC 29853)
DERCHI Windows and Doors: Elevating a South Carolina Custom Home
In Williston, South Carolina, DERCHI Windows and Doors supplied the complete window and door package for a new custom residence — a single-family home built with advanced American framing and ZIP System sheathing, finished with a brick veneer base and a shingle roof.
The project demonstrates how DERCHI products are engineered for the American residential market: large-format openings, factory-controlled tolerances, and finishes that hold up decade after decade in the humid subtropical climate of the southeastern United States.
The Product Package
The order covered the full envelope of the home, including:
· Multi-panel sliding glass doors — five-panel assemblies framing the main living areas and opening onto the rear terrace.
· Casement and awning windows — black-framed units set in both the front elevation and the gable ends.
· Twin and triple window groupings — matching sightlines across the bedroom and living zones.
· Custom entry door with arched opening — factory finished in black, fitted with multi-point locking hardware.
Why These Products Fit South Carolina
South Carolina sits in a humid subtropical zone: strong summer sun, heavy seasonal rain, and high humidity that punish lower-grade materials. Aluminum systems are the natural answer, and DERCHI's all-aluminum construction brings the following advantages:
· Corrosion-resistant aluminum profiles — no swelling, no warping, no rot, unlike timber alternatives.
· Thermal break technology — keeps conditioned air in and summer heat out, reducing load on HVAC systems.
· Multi-point locking hardware — security that satisfies American residential expectations.
· Weather-tight sealing — tested assemblies that resist wind-driven rain and air infiltration.
Installation in Progress
The photographs from the site record the installation of the black-framed units into the timber frame at various stages. The large sliding door assemblies were set into the wall openings before interior finishing, allowing precise alignment with the framing.
The pre-finished black frames arrive with protective film and factory labels, ready for immediate installation — a workflow that saves time on site and reduces the risk of damage to the finished surface.
Custom Manufacturing, Not Standard Stock
Because the home is a custom design, the openings are not standard sizes. DERCHI manufactured each unit to the project's exact dimensions, with matching frame profiles across all windows and doors so that the elevations read as a single coherent design.
This is the core advantage of working with a manufacturer rather than a distributor: sizes, colors, and configurations are made to order, and every unit on the project shares the same profile system and finish.
