Featured export-grade bay, casement, awning, and hung fenestration systems certified for high wind-load resistance, hurricane monsoon protection, and superior solar heat control.
Analyzing the evolution of high-rise residential projects, luxury urban villas, and hospitality hubs across Dhaka, Chattogram, and Sylhet.
Bangladesh experiences intense solar radiation and high temperatures for eight months of the year. Traditional single-pane aluminum windows act as thermal bridges, driving massive HVAC power costs in metropolitan areas like Dhaka (Gulshan, Banani, Dhanmondi). Our bay windows utilize triple-silver Low-E glass (LoĒ³-366) and PA66 thermal breaks, stopping up to 78% of infra-red solar heat gain while preserving natural daylighting.
The annual monsoon season brings horizontal, wind-driven rain with precipitation rates exceeding 300mm per month. Standard sliding windows frequently flood indoor living spaces. Our engineered bay windows integrate continuous fusion-welded frame corners, sloped weeping sills, and multi-tier EPDM bulb weatherstripping rated to withstand water penetration pressures up to 700 Pa.
Traffic densities in major commercial corridors generate continuous ambient noise levels between 75 dB and 95 dB. By incorporating asymmetric double glazing (e.g., 6mm + 12Ar + 8mm) or laminated PVB acoustic glass into rigid multi-chambered vinyl bay window frames, sound transmission is reduced by up to 42 dB, creating serene interior environments for luxury developments.
Information Gain Insight for Importers: Bay windows expand internal usable floor area without altering building foundations. In high-density Bangladeshi real estate markets where square footage commands premium prices, installing cantilevered 30° or 45° angled bay windows adds tangible structural value, 180-degree panoramic daylighting, and enhanced curb appeal to high-rise residential facades.

Customizing bay fenestration profiles for targeted regional building archetypes and climate zones.
In high-end developments in Gulshan 1 & 2, Banani, and Uttara, developers utilize our 45-degree angled vinyl bay windows equipped with integrated crank casement openings. The 180-degree projection increases internal living room space while allowing cross-ventilation during humid spring months and total sealing against heavy winter dust smog.
Coastal Bangladesh faces harsh marine saline air and high cyclone wind gusts. Our heavy-duty thermal break aluminum bay windows feature AAMA 2605 fluorocarbon powder coating that resists salt fog corrosion without chalking or fading. Coupled with 12mm laminated safety glass, these systems withstand wind loads exceeding 3.5 kPa.
For corporate headquarters in the port city of Chattogram, custom box bay windows (90-degree design) offer dedicated view nooks overlooking maritime terminals. Fitted with reflective solar control double-glazed glass, these systems drastically lower building operational carbon footprints and HVAC expenses.
Vertical manufacturing control ensuring uncompromised precision, compliance, and export logistics support.
We own and operate precision extrusion die lines. By maintaining complete control over raw material compounding—using 100% virgin uPVC resin with high titanium dioxide (TiO2) content—our profiles will not yellow, crack, or become brittle under severe tropical UV exposure.
Unlike mechanically screwed frames that loosen and leak over time, our vinyl bay window corners are fusion-welded at 250°C into a single monolithic structural frame. Corner strength tests prove weld points are stronger than the profile wall itself.
Our automated insulated glass (IG) manufacturing line features warm-edge spacer application, dual-stage butyl perimeter sealing, and automated high-purity Argon gas injection, guaranteeing zero seal failure or internal condensation for decades.
We provide full export crating, fumigated plywood framing, and direct container loading (20ft / 40ft HQ) shipped straight to Chattogram Port (Port of Chittagong). Complete import paperwork including Certificate of Origin (COO), Commercial Invoice, and Packing Lists are issued for seamless Bangladesh customs clearing.
Addressing commercial, technical, and logistical queries from Bangladeshi developers, architects, and importers.
We manufacture custom bay windows in standard 30-degree, 45-degree, and 90-degree (box bay) configurations, as well as custom-curved bow windows. Every unit is built to order in precise 1/8-inch (3mm) increments according to your architectural window schedule. Structural steel-reinforced mullions and tension rods are integrated to guarantee load-bearing capacity for cantilevered elevations.
Our vinyl profiles are extruded from 100% virgin uPVC compound blended with high concentrations of UV stabilizers (Titanium Dioxide). This ensures the material resists thermal expansion, color degradation, and chalking even during 40°C+ summer peaks. uPVC is inherently non-conductive, making it a far superior thermal insulator compared to standard non-thermal aluminum frames commonly found in local markets.
Yes. We routinely work with commercial importers, real estate developers, and construction firms in Bangladesh. We accept Irrevocable Letters of Credit (L/C at Sight) issued by reputable Bangladeshi commercial banks (such as Eastern Bank, Prime Bank, HSBC Bangladesh, etc.), adhering strictly to international trade regulations and pro-forma invoice documentation.
Orders are packaged with protective corner guards, scratch-resistant plastic wrapping, and heavy-duty fumigated wooden crates. We manage container loading (FCL 20GP/40HQ) directly from our factory warehouse to shipping ports. Average transit times from our facility to Chattogram Port range from 14 to 22 days depending on the shipping line.
Yes. Our heavy-duty window profiles and structural mullion connections are engineered and tested in accordance with ASTM E330 structural performance standards. They are rated to withstand severe wind loads up to 3500 Pa (equivalent to wind speeds exceeding 240 km/h), making them fully suitable for coastal cyclone zones in Cox's Bazar, Chittagong, and Barishal.
For high-noise urban corridors, we recommend specifying dual-pane insulating glass units with unequal pane thicknesses (e.g., 6mm outer glass + 12mm Argon space + 8mm inner glass) or laminated acoustic glass with a 0.76mm PVB interlayer. This combination disrupts sound waves across multiple frequency bands, achieving Sound Transmission Class (STC) ratings between 38 dB and 42 dB.
We provide a written Limited Manufacturer Warranty covering vinyl profiles and aluminum extrusions against material defects, cracking, and chalking for 20 years. Insulating glass units are warranted against seal failure and internal fogging for 10 years, and hardware mechanisms (cranks, locks, hinges) are covered for 5 years with direct spare parts replacement support.
