Product Details
Engineered for aluminium bifold door United States applications, DERCHI bifold doors use thermally broken aluminium frames to cut heat transfer and condensation. Panels fold to one or both sides, clearing the whole opening—unlike sliding doors that keep half the space blocked. This full access suits patios, restaurant terraces, and hotel event spaces while maintaining strong wind and water resistance.
For aluminium folding doors United States projects, sill selection matters: fully weathered, low‑level, or water‑resistant tracks match different exposure levels. Across 78, 80, and 93 series, multi‑layer tempered insulating glass options include Low‑E coatings, laminated safety glass, and argon gas. The 80 series even offers a 90‑degree corner folding design for patio bifold doors that need a seamless glass‑curtain effect, while Jiangyin Haida EPDM rubber strips guard against wind‑driven rain and air infiltration.
Product Features
Thermal break efficiency: Thermally broken aluminium profiles plus insulating glass lower U‑factors and condensation risk, helping meet U.S. energy codes for different climate zones.
Glass flexibility: Choose double, triple, Low‑E, laminated, or tinted glass to manage solar heat gain, visible light, and acoustic comfort project by project.
Tested hardware: KERSSENBERG or CMECH handles, hidden hinges, and multi‑point locks deliver smooth folding and enhanced forced‑entry resistance.
Multi‑point locking: Extra locking strikes along the meeting stile keep panels aligned under wind loads, important for wide exterior bifold doors in exposed locations.
Adjustable sills: Select fully weathered, low‑level, or water‑resistant sills to meet drainage, threshold, and accessibility requirements.
NFRC‑ready data: 93 Series U‑Factor and SHGC values are available; test reports can be requested for any configuration to streamline your submittal.
Customizable Styles
Glass type: Upgrade to triple tempered, laminated, Low‑E, reflective, or tinted glazing—ideal for custom aluminum bifold doors targeting specific SHGC or sound ratings.
Frame finish: Powder coating, anodized wood grain, or PVDF in a broad color palette to match architectural palettes and coastal durability needs.
Frame depth: Profiles available in 47mm, 70mm, 75mm, and 100mm to suit wind loads and structural back‑up.
Opening direction: Doors can fold inward or outward, depending on patio layout, floor space, and egress codes.
Sill design: Options include fully weathered, low‑level saddle, and water‑resistant track; confirm with supplier for your project’s exposure.
Hardware Accessories
Handles & locks: KERSSENBERG or CMECH hardware with multi‑point locking; finish compatibility with frame colors.
Hidden hinges: Concealed pivot hardware maintains clean sightlines and protects moving parts from weather—essential for exterior bifold doors USA installations.
Multi‑point strikes: Extra locking points stiffen the panel assembly against wind pressures and improve air tightness.
Weather seals: Jiangyin Haida EPDM rubber and integrated bent duckbill seals create continuous water‑ and air‑tight barriers, critical for high‑rain zones.
Integrated blinds: Optional 26A magnetic or 27A solar‑powered blinds inside the glass cavity offer daylight control with zero dust exposure.
