Constructed with high-tensile 6063-T6 virgin aluminium extrusions, structural double-tempered glass, and tropical-grade EPDM weather stripping. Each door model is rigorously tested to EN 14351-1 and CE benchmarks, guaranteeing zero moisture delamination and superior dimensional stability.
The Kingdom of Thailand presents a distinct microclimatic profile characterized by continuous thermal loads, elevated ambient humidity fluctuating between 75% and 92%, and intense monsoon-driven moisture saturation. Standard interior glass doors engineered for temperate North American or Central European environments frequently succumb to galvanic corrosion of hardware, fungal spore propagation along interior glazing seals, and excessive HVAC energy loss caused by thermal bridging between conditioned living spaces and non-conditioned zones.
Unlike locally converted scrap extrusions that contain uncontrolled iron and zinc trace impurities, DERCHI deploys 100% primary A00 aluminium ingots extruded to 6063-T6 temper. With tensile strength exceeding 240 MPa and web thicknesses up to 2.2mm, our slender interior stiles withstand continuous dynamic wind currents from balcony drafts and building pressurization cycles without sash warp or latch misalignment.
In luxury residences where interior air conditioning is sustained at 20°C while ambient service corridors reach 36°C with 85% RH, thermal bridging can cause heavy surface condensation. Our thermal break internal profiles incorporate continuous Polyamide PA66 GF25 insulation barriers that maintain internal surface temperatures above the dew point, effectively eliminating the risk of water run-off and toxic black mold growth.
Every pane installed in our internal glass doors undergoes convection tempering conforming strictly to CE standard EN 12150-1 and Thai building safety protocols. From 8mm monolithic ultra-clear Low-Iron tempered glass to 5mm+0.76PVB+5mm acoustic laminated configurations, our glass maintains 4 to 5 times the impact resistance of standard annealed glass, shattering into blunt, harmless granules in rare fracture events.

From super-tall luxury towers towering over Sukhumvit to sea-facing infinity villas nestled into the rocky headlands of Koh Samui, interior fenestration demands precise tailoring to the spatial and environmental demands of each regional typology.
High-rise developments along Wireless Road, Thonglor, and the Chao Phraya riverfront require acoustic zoning between master sleeping suites, living spaces, and home working environments to combat street-level decibels and mechanical riser hum.
Tropical island villas continuously expose interior hardware and finishes to airborne sea salts and rapid shifts between air-conditioned interiors and open-air tropical terraces. Corrosive degradation is the primary failure mode of secondary metals.
Northern Thailand's biophilic architectural masterplans emphasize organic ventilation, abundant daylight transmission, and visual continuity connecting interior sanctuaries with mist-shrouded jungle landscapes.
Corporate headquarters and clean industrial research facilities in Rayong and Chonburi demand commercial-cycle endurance, fire-integrity compliance, and seamless integration with electronic access control systems.
The evolving landscape of Thai high-end residential and commercial architecture is shaped by energy-conservation mandates, ultra-minimalist industrial design, and acoustic wellness.
Bulky 50mm perimeter frames are rapidly being phased out by Thai architects in favor of ultra-narrow stiles measuring 12mm to 16mm. This architectural movement maximizes glazed surface area, creating continuous sightlines and spatial transparency in space-constrained metropolitan condominiums.
As property developers seek certification under the Thai's Rating of Energy and Environmental Sustainability (TREES) and USGBC LEED v4.1, interior envelope components must contribute directly through zero VOC powder coatings, 100% recyclable aluminium billets, and thermally broken profiles that reduce air-conditioning heat gain.
With luxury Bangkok living spaces serving simultaneously as remote professional workstations and entertainment hubs, demand for internal doors achieving certified Rw ratings of 38dB to 42dB has surged by 180% year-on-year, driving adoption of acoustic PVB interlayers and perimeter air gaskets.
Mechanical strike plates with abrasive click noise are being replaced by German-engineered silent magnetic flush locks and motorized concealed overhead tracks that integrate seamlessly into Crestron and Control4 smart home automation ecosystems.
