Precision-engineered aluminum profile systems fully compliant with BNBC 2020 wind pressure load and acoustic insulation requirements.
An in-depth technical analysis for developers, MEP contractors, and structural engineers in Dhaka, Chittagong, and Sylhet sourcing high-performance fenestration systems from Foshan, China.
Bangladesh’s coastal belt and urban high-rises experience severe tropical storm wind pressure. Our profile extrusion walls (1.4mm - 2.0mm T6 grade) are structural engineered to withstand basic wind speeds up to 260 km/h under BNBC 2020 parameters.
Annual precipitation in Bangladesh exceeds 2,500mm. Standard sliding windows fail under driving rain. We implement multi-barrier EPDM gasket weatherstripping paired with hidden drainage weep-holes to prevent water ingress during intense monsoons.
Dense traffic noise in Gulshan, Banani, and Motijheel requires high sound attenuation. Our double glazed insulated glass units (IGU) achieve an STC rating of 38-42 dB, reducing outdoor decibels to quiet interior levels.
Comparing standard window parameters against high-performance tropical fenestration standards exported to Bangladesh.
| Performance Parameter | Standard Local Specification | Doorreme Export Grade (China Base) | Engineering Benefit |
|---|---|---|---|
| Aluminium Alloy Profile | 6063-T5 (1.2mm wall thickness) | 6063-T6 High-Tensile (1.4mm - 2.0mm) | Prevent frame deflection in high-rise towers |
| Surface Coating System | Standard Anodized / Basic Powder | AkzoNobel PVDF Fluorocarbon (3-Coat) | Resists coastal salt spray & severe UV fading |
| Glass Configuration | 5mm Single Clear Float Glass | 6mm Low-E + 12A Argon + 6mm Tempered | Reduces Solar Heat Gain (SHGC ≤ 0.28) |
| Sash Balancer Mechanism | Friction Stays / Basic Pulley | Precision Stainless Steel Spiral Balancers | Smooth 50,000+ cycle vertical sliding operation |
| Acoustic Performance | STC 22 - 25 dB | STC 38 - 45 dB (Laminated IGU option) | Blocks heavy street traffic & generator noise |
| Hardware & Lock Set | Local Zinc Alloy Handles | German Roto / Siegenia Multi-point Locks | Enhanced security against forced entry |
From luxury residential towers in North Dhaka to coastal commercial complexes in Chittagong, explore how our aluminium systems adapt to regional architectural challenges.
Dense urban environments demand minimal space consumption and maximum daylight yield. Our vertical sliding sash windows and ultra-narrow frame sliding doors allow seamless ventilation without intruding into interior floor space.
Salt-laden sea breezes quickly erode untreated aluminium frames and hardware. We deliver ocean-grade PVDF coatings with a thickness exceeding 30 microns, backed by stainless steel fasteners and marine-grade anodized profiles.
Key design shifts shaping the procurement of imported fenestration products among top Bangladeshi real estate developers and contractors.
With LEED-certified factories and green residential projects expanding across Gazipur and Dhaka, developers prefer thermally broken aluminium profiles with U-values below 1.8 W/m²K to satisfy sustainability audits.
Modern villa owners and hotel operators are replacing thick traditional timber/aluminium profiles with minimal sightline narrow-frame windows, expanding glass sightlines by up to 22% additional daylight.
Due to high humidity and mosquito prevalence, fenestration specs now universally mandate integrated high-tensile SS304 mesh screens embedded into the main frame track without compromising exterior aesthetics.
