Kitchen Sliding Glass Door

Multi-Track Sliding System

The WT-105B supports four-track and five-track configurations, working as either a 4 panel sliding door or 5 panel sliding door setup. This allows wide openings between your kitchen and adjacent spaces like dining rooms or patios, with panels sliding along separate tracks for independent movement.

Full Glass Panel Design

Each panel uses a single uninterrupted glass area, allowing natural light to reach deeper into the kitchen. Without divided panes, the sightline between indoor and outdoor spaces stays open, which suits open-plan layouts where the cooking area connects to a patio or garden.

Internal and External Gluing Technology

Glass-to-frame joints use structural bonding on both the inside and outside surfaces rather than exposed mechanical fasteners. This approach strengthens the assembly, helps it hold shape through temperature shifts, and keeps surfaces flat — resulting in a kitchen sliding glass door that looks clean from both sides.

Embedded Frame Structure

The frame sits flush within the wall opening rather than protruding outward, reducing the visible edge around the door. This gives the aluminum sliding glass door a built-in appearance and minimizes ledges where dust and grease can collect in cooking areas.

Wool Strip Sealing System

Sealing strips are fitted between panels and along frame contact points to close gaps that allow air, dust, and moisture through. In kitchens, this helps contain cooking odors, limits outside particles from reaching food preparation surfaces, and supports a more controlled indoor environment.

Improved Air Tightness

The WT-105B reduces air leakage across joints, tracks, and panel edges through its combined sealing and frame design. For kitchens, this means less outside air entering the space, which helps keep room temperature stable and reduces the load on heating or cooling systems.

Double Tempered Insulated Glass

Each panel holds two tempered glass panes with a sealed argon-filled gap between them. Tempered glass resists impact better than standard glass, and the insulated gap slows heat transfer — a practical pairing for a kitchen sliding glass door exposed to sun or outdoor weather.

Reliable Hardware Configuration

The door ships with a HOPPE straight lock and a 304 stainless steel single hook lock. Both components resist corrosion from cooking humidity and frequent handling, making them practical choices for a kitchen entry point that sees daily use.

U-Factor — 0.39

The WT-105B records a U-Factor of 0.39. This number measures how much heat passes through the door. A lower value means less heat transfer. At 0.39, this aluminum sliding glass door limits heat gain in summer and heat loss in winter. DERCHI uses an insulating barrier within the frame to achieve this result.

Wind Pressure Resistance — 5 KPa

The WT-105B withstands wind pressure up to 5 KPa. DERCHI built the aluminum frame and glass panels to hold position under sustained wind force. This rating suits homes in coastal or high-wind regions. Whether installed as a 4 panel sliding door or 5 panel sliding door, the structure maintains integrity during storms.

SHGC — 0.25

SHGC stands for Solar Heat Gain Coefficient. The WT-105B scores 0.25, meaning it blocks 75% of solar heat. This matters for kitchen doors that face direct sunlight. DERCHI offers this rating as part of its custom glass sliding doors options. A low SHGC keeps the kitchen cooler and reduces air conditioning costs.

Water Tightness — 450 Pa

The WT-105B kitchen sliding glass door holds against water pressure up to 450 Pa. DERCHI tests this rating under simulated storm conditions. At 450 Pa, the door prevents rain from entering the kitchen through frame or track joints. This protects flooring, cabinetry, and walls near the door opening.

Air Tightness — 4.5m³/(m·h)

DERCHI rates the WT-105B at 4.5 for air tightness. The sealed aluminum frame and track system limit air leakage between the kitchen and outside. Less air leakage reduces the load on heating and cooling systems. Homeowners notice lower energy bills and a stable indoor temperature year-round.

Sound Insulation — 30 dB

This kitchen sliding glass door reduces outside noise by 30 dB. DERCHI achieves this through the combination of glass thickness, aluminum frame construction, and sealed track design. A 30 dB reduction blocks common sounds like traffic and lawn equipment. This makes the kitchen a quieter space for cooking and conversation.

Apartment

Apartments often lack room for hinged doors near the kitchen. The WT-105B Series kitchen sliding glass door operates on a horizontal track, eliminating the need for swing clearance. This frees up 8–12 square feet of usable floor area. The aluminum frame withstands kitchen humidity without rusting. A 4 panel sliding door configuration fits standard apartment openings from 2400mm to 3600mm wide. The glass barrier contains cooking fumes within the kitchen zone.

Home Office

Noise from kitchen appliances disrupts remote work. This aluminum sliding glass door creates a sound-reducing partition between the kitchen and workspace. The glass maintains a visual connection so users can watch over cooking or children. DERCHI offers custom glass sliding doors to fit non-standard openings found in retrofitted rooms. The WT-105B track system operates quietly, preventing disruption during video calls or focused work sessions.

Hotel

Hotel kitchenettes and prep areas require doors that handle hundreds of daily open-close cycles. The WT-105B Series uses reinforced aluminum rollers rated for high-frequency operation. A 5 panel sliding door layout covers service openings up to 5000mm wide, common in hotel buffet or catering zones. The glass surface accepts standard commercial cleaning agents. This kitchen sliding glass door blocks heat and odor transfer from the kitchen to guest-facing dining areas.

Office Building

Office pantries serve multiple employees throughout the day. The WT-105B aluminum sliding glass door separates food preparation from workstations. It contains odors from microwaves and cooking within the pantry area. The sliding mechanism needs zero swing space, preserving corridor width for foot traffic and fire code compliance. Staff can check kitchen occupancy through the glass before entering. DERCHI builds each door to match the opening dimensions of the specific office layout.

Outdoor

Connecting an indoor kitchen to an outdoor dining or barbecue area requires weather resistance. The WT-105B Series aluminum frame undergoes anodizing treatment to resist salt air and moisture corrosion. A 4 panel sliding door opens up to 75% of the total frame width, merging indoor and outdoor zones for events. When closed, sealed rubber gaskets block wind, rain, and insects. The recessed track prevents water from pooling at the kitchen threshold.

Residential building

Multi-unit residential buildings need kitchen doors that meet fire separation and ventilation standards. The WT-105B kitchen sliding glass door provides a physical barrier between cooking zones and shared hallways. DERCHI supplies custom glass sliding doors sized to each unit plan, reducing on-site modification. The aluminum frame tolerates seasonal temperature changes from -20°C to 60°C without deformation. Property managers benefit from low maintenance — the track requires only periodic cleaning to function.

Exterior

Exterior-facing kitchen installations expose doors to UV radiation, rain, and temperature shifts. The WT-105B Series uses powder-coated aluminum that resists fading and peeling over years of sun exposure. The sealed glass panel reduces outside noise by up to 30 dB. A 5 panel sliding door option covers wide exterior openings up to 6000mm. The multi-point locking system secures the kitchen entry against forced access from outside.

Villa

Villas feature wide kitchen openings that connect to gardens, pools, or dining halls. Standard doors cannot span these openings. The WT-105B Series supports 4 panel sliding door and 5 panel sliding door configurations to cover widths beyond 4000mm. DERCHI provides custom glass sliding doors matched to each villa's architectural dimensions. The aluminum sliding glass door maintains unobstructed views through floor-to-ceiling glass while separating climate-controlled kitchen interiors from exterior environments.
