Engineered structural window solutions selected specifically for Gitarama’s high-altitude UV resistance and structural performance requirements.
As Rwanda’s primary geographical hub and a crucial secondary city under the National Strategy for Transformation (NST1), Gitarama (Muhanga District) is undergoing rapid urbanization. The rise of multi-story commercial plazas, institutional hubs, and upscale residential developments has driven a strict demand for high-performance building envelopes. However, Gitarama’s unique physical geography presents challenging environmental parameters for exterior fenestration systems.
Situated at an average elevation of 1,800 meters above sea level, the district experiences a tropical highland climate with intense, unfiltered solar ultraviolet (UV) radiation. Additionally, Gitarama experiences alternating heavy rainy seasons characterized by high-velocity wind loads and driving rain. Standard window fixtures degrade rapidly under these conditions, leading to color fading, thermal bridging, and water ingress.
To meet the strict building codes of Rwanda's green building compliance system, windows deployed in Gitarama must utilize high-spec materials. Our systems optimize thermal transmittances (U-Value) and solar heat gain coefficients (SHGC) to match localized requirements:
| Performance Indicator | Target Requirement |
|---|---|
| U-Value (Thermal Transmittance) | ≤ 2.2 W/m²·K |
| Wind Load Resistance | Class 4 (≥ 3000 Pa) |
| Acoustic Attenuation (STC) | ≥ 35 dB |
| Surface Coating Standard | AAMA 2604 / AAMA 2605 |
Providing high structural integrity and energy efficiency through German engineering and premium metallurgy.
We utilize premium architectural-grade 6063-T5/T6 and 6060-T66 aluminum-magnesium-silicon alloys. Extrusion profiles feature optimized wall thicknesses (1.4mm to 3.0mm) strictly conforming to international standards (EN 12020-2 / GB/T 5237). This provides the structural load capacity necessary to resist high wind forces in high-altitude developments without structural deflection.
To counteract the strong temperature swings between Gitarama's sun-drenched afternoons and cool highland nights, our windows employ PA66-GF25 (polyamide reinforced with 25% fiberglass) thermal barrier strips. This thermal break prevents thermal bridging, ensuring indoor comfort while reducing HVAC energy loads.
Our windows incorporate insulated glass units (IGUs) with low-emissivity (Low-E) coatings, filled with 90% Argon gas, and separated by warm-edge spacers. Primary and secondary sealing using high-grade vulcanized EPDM gaskets ensures long-lasting airtightness and moisture barriers.
Our standard industrial factory relies on high-grade management systems and advanced German window technologies. For over 10 years, we have integrated design, engineering, and sales to deliver high-quality fenestration systems globally.
The company relies on modern standard factory buildings and management systems, introduces advanced German door and window technology, gathers senior designers in the industry, focuses on aluminum alloy doors and windows for 10 years, and provides integrated services from design to sales. The product line covers balcony sliding doors, indoor partition doors, sliding windows, casement windows, and folding doors, all of which follow high standard production processes to ensure excellent quality.

Custom commercial fenestration engineering for developers and contractors in Gitarama and across Rwanda.
For mid-rise and high-rise commercial structures in Gitarama's developing business districts, we offer engineered structural glass systems. These feature heavy-duty mullions and transoms designed to withstand localized wind loads without compromising safety or aesthetic performance. Our systems integrate seamlessly with standard exterior cladding systems.
Schools, administrative buildings, and hospitals require durable systems with low operational maintenance. Our tilt-and-turn and heavy-duty sliding systems feature multi-point locking mechanisms, robust structural members, and high acoustic insulation ratings, making them ideal for high-traffic environments.
High-end residential developments in Gitarama demand large glass panels, minimal frame visibility, and seamless indoor-outdoor transitions. Our high-performance sliding doors and folding systems support heavy glass weights while ensuring smooth operation via stainless steel roller guides and precision-fit hardware.
BIM & CAD Support: We supply full AutoCAD shop drawings, dynamic BIM families (Revit compatible), and section designs to integrate directly into architectural plans, simplifying approval stages with local planning authorities.
Sourcing building materials globally requires reliable logistics. Our supply chain is structured to handle international shipping, customs clearance, and local transit. Shipping routes from our China industrial facilities to East Africa generally transit through the ports of Mombasa (Kenya) or Dar es Salaam (Tanzania), followed by overland transport to Kigali and on to Gitarama via the Kigali-Muhanga Highway.
All packaging uses seaworthy, fumigated plywood crates with shock-absorbing corners to prevent transit damage. This ensures the systems arrive on site ready for direct installation.
Our aluminum extrusion profiles and structural glass units strictly comply with the requirements of the Rwanda Standards Board (RSB) and East African construction standards. Testing certifications include:
A structured approach to custom window and door manufacturing from initial drawing submission to final site delivery.
Submission of window schedules, elevation designs, and wind-load metrics for structural and thermal calculation.
Development of detailed section drawings, joint details, and anchors for project engineering approval.
CNC-controlled cutting, milling, punching, assembly, glazing, and multi-stage quality control checks.
Safe crating, customs documentation, sea shipping, and inland delivery to site in Gitarama.
Answering common engineering, procurement, and logistical questions regarding window systems in Rwanda.
A full range of weather-resistant sliding, casement, folding, and awning window configurations suitable for residential and commercial architecture in Gitarama.
