Explore our integrated fenestration assemblies, custom French door structural components, and high-performance glass balustrades engineered for Sri Lankan tropical environments.
The architectural landscape across Sri Lanka—spanning the cosmopolitan high-density corridors of Colombo 03 and Colombo 07 to the salt-laden microclimates of Galle, Bentota, Mirissa, and Weligama—is experiencing a profound structural transition. For decades, traditional timber French doors (fashioned from local Teak, Jak, or Nadun) reigned supreme under the legacy of Geoffrey Bawa's "Tropical Modernism". However, the unrelenting tropical realities of Sri Lanka—marked by sustained relative humidity fluctuating between 75% and 92%, annual monsoonal deluge cycles (South-West and North-East monsoons), and aggressive airborne salinity—frequently induce timber dimensional distortion, fungal rot, termite infestation, and frame binding within 24 to 36 months of occupancy.
As a consequence, Sri Lankan tier-one property developers, boutique hotel hoteliers, and luxury private homeowners are systematically specifying precision-engineered aluminium French doors. Advanced 6063-T6 architectural grade aluminium alloys, coupled with thermal break polyamide isolators and marine-grade protective finishes, offer absolute dimensional stability, zero water ingress under windward monsoon pressures (>600 Pa), and structural spans that accommodate floor-to-ceiling panoramic glass panes impossible to execute with organic framing materials.

From saline sea spray along the Southern coastline to misty high altitudes in the Central Highlands, our custom aluminium French doors are tailored to local microclimatic requirements.
Villas situated in Galle, Mirissa, Tangalle, and Bentota directly face Indian Ocean saline winds. Our French doors deploy 25-micron anodic oxidation, 316-grade stainless steel concealed hinges, and multi-point perimeter compression seals to eliminate salt aerosol corrosion and air conditioning thermal leakage.
Galle & Weligama Coastal SpecFor luxury towers in Colombo 02, Havelock City, and Colombo Port City, high-altitude lateral wind shear is a dominant hazard. We fabricate reinforced structural profiles capable of withstanding dynamic wind loads exceeding 2,400 Pa while acoustic double-glazing isolates urban traffic decibels down to 32 dB.
Colombo Urban High-PressureIn cooler, moist elevations like Nuwara Eliya, Kandy, and Ella, daytime solar radiation rapidly shifts into chilled, humid nights. Our thermal-break aluminium French doors eliminate internal profile condensation, stopping thermal bridging while maintaining comfortable indoor temperatures without heating overdrive.
Central Highlands Thermal BreakColonial and Dutch-era architectural conversions in Colombo Fort and Galle Fort demand authentic multi-lite mullion layouts paired with cutting-edge performance. We engineer slimline heritage sightlines with simulated divided lites (SDL), preserving historical character alongside modern security standards.
Heritage Preservation CompliantThe Sri Lankan building sector is currently navigating significant economic and ecological evolutions. With energy costs rising and building codes aligning with green certification protocols (such as GREENSL® and LEED Sri Lanka), fenestration is no longer viewed merely as an aesthetic opening—it is evaluated as a primary building envelope thermal performance barrier.
Key Market & Technical Trends Include:
Combining over 15 years of metallurgical fabrication pedigree, certified virgin billets, zero-compromise precision CNC assembly, and comprehensive support for local and remote diaspora clients.
Unlike broker agencies or field assemblers who purchase pre-cut sections, our dedicated fabrication plant maintains direct metallurgical quality control from raw extrusions to precision CNC corner crimping and final glazing.
Every structural opening is recorded using digital laser measuring stations within 24 hours of request. There are zero standard catalog size limitations—every single sash is fabricated to match opening plumb, level, and squareness.
We source certified structural architectural extrusions engineered to strict BS EN 12020 and ASTM B221 specifications. Virgin billet formulations prevent intergranular micro-corrosion typical in unchecked scrap melts.
Cutting, pneumatic mechanical corner jointing, structural two-component polyurethane bonding, and tempered double-glazing installations occur inside our dust-controlled plant prior to site delivery, guaranteeing air-tight joints.
Trusted by Sri Lankan expatriates in the UK, Australia, the US, Canada, and the GCC building high-end properties at home. Receive real-time laser survey logs, CAD drawings, video QA reviews, and milestone reports remotely via WhatsApp and email.
We do not conclude our engagement upon project handover. Our service division provides hardware alignment, gasket inspections, stainless steel hardware maintenance, and replacement guarantee programs for complete reliability.
Even the most sophisticated thermal-break French door will fail prematurely if installed by third-party masonry laborers lacking fenestration calibration tools. In tropical environments, capillary water action and lateral wind pressures exploit the smallest 1mm silicone void or frame misalignment.
Every door manufactured by our facilities is placed by our own certified installation engineers:
Authoritative technical guidance compiled by fenestration engineers to answer common queries from homeowners, project managers, and quantity surveyors.
We use primary virgin architectural 6063-T6 or 6060-T6 aluminium alloy profiles compliant with BS EN 755 and Sri Lanka Standards (SLS). For standard work, premium national profiles like Alumex, Pak Alco, and Chawla are utilized, alongside proprietary imported thermal break profiles for luxury villas requiring superior thermal and wind resistance.
In coastal splash and high-salinity zones (classified as ISO 12944 C4 to C5 environments), standard powder coat fails within 18 months. We mandate Qualicoat Seaside Class 2 architectural powder coatings (60 to 80 microns) or anodized surface finishes with a thickness of 20 to 25 microns. Furthermore, all exposed screws, mortise locksets, and pivots are made from Marine Grade 316 Stainless Steel.
Prices vary significantly based on specifications: Standard heavy-duty powder-coated French doors with 6mm-8mm single tempered glass start from Rs. 1,600 to Rs. 2,400 per sq. ft. High-performance, thermally broken European profiles featuring double-glazed Low-E insulated glass (DGU) with concealed multi-point security locking range between Rs. 3,200 and Rs. 5,500+ per sq. ft., inclusive of site engineering and installation.
Our systems utilize an engineered three-tier water defense matrix: (1) Dual-gasket vulcanized EPDM compression seals along the entire door rebate; (2) A stepped sub-sill threshold with internal weep channels designed to balance wind pressure; and (3) Concealed drainage weep baffles that release pooled rainwater outward even under 600 Pa windward rainstorms.
Yes. A considerable proportion of our architectural fenestration clients are non-resident Sri Lankans (NRSLs) residing in the UK, Australia, UAE, Canada, and Europe. Our engineering team conducts on-site laser surveys, coordinates directly with your project architect or local general contractor, generates full CAD cross-sections for sign-off, and provides digital progress documentation throughout installation.
Following opening confirmation via laser survey, standard architectural finishes (matte black, bronze anodized, traffic white) are typically fabricated and ready for site mounting within 14 to 21 working days. Custom color matching, dual-color extrusions, or imported automated PDLC smart glass assemblies generally require 4 to 6 weeks for complete processing and testing.
Yes. We regularly fabricate Simulated Divided Lite (SDL) French doors that preserve classic Dutch-Colonial and British-era architectural aesthetics in areas like Colombo Fort, Cinnamon Gardens, and Galle Fort. The internal and external aluminium muntin grids are precision-milled and bonded to structural double-glazed units, providing authentic character with modern security and energy performance.
We provide a 10-year structural warranty on aluminium profile integrity and extrusion geometry, a 10-to-15-year warranty on Qualicoat surface treatments against peeling and chalking, and a 3-year performance warranty on mechanical hardware, hinges, and locksets, supported by our local engineering response team.
