#1 Curtain Wall & Facade Interiors Services in Pakistan | ACCO

Walk through any modern commercial district in Lahore, Karachi, or Islamabad. What catches your eye? The buildings with floor-to-ceiling glass. The ones where the boundary between inside and outside dissolves. Light floods the interior. Views connect to the city. The facade looks sleek, sophisticated, contemporary. These buildings command higher rents. They sell faster. They attract better tenants. The secret is not expensive finishes inside. The secret is the curtain wall – a non-structural glass facade that transforms how a building looks, feels, and performs.

Ahmed Construction Company (ACCO) delivers these transformations with professional Curtain Wall & Facade Interiors services in Pakistan. For over 25 years, we have delivered architectural design services in Pakistan to prestigious clients like Meezan Bank, Bata, and BUITMS. Our facade engineering service is comprehensive – we design, engineer, and install curtain wall systems that integrate perfectly with your building’s interior and exterior.

Curtain walls are not windows. They are engineered systems of aluminium framing and glass panels (sometimes stone or metal panels) that hang from the building structure like a curtain – hence the name. They resist wind loads, seismic movements, and water penetration. They manage solar heat gain. They provide thermal insulation. And they create interiors filled with natural light – reducing artificial lighting costs by up to 50% and improving occupant wellbeing. Whether you need a unitized curtain wall for a high-rise commercial tower, a stick-built system for a corporate headquarters, or a glass facade for a retail showroom, ACCO delivers engineered facade solutions that balance aesthetics, performance, and budget.

What Are Curtain Wall & Facade Interiors Services in Pakistan?

Curtain Wall & Facade Interiors services encompass the complete design, engineering, fabrication, and installation of non-structural building facades – primarily glass curtain walls, but also including aluminium composite panel (ACP) cladding, stone veneer facades, and other rainscreen systems. These facades are “curtain walls” because they are attached to the building structure but do not support the building’s weight. They curtain or hang off the edge of the floor slabs.

In the Pakistani commercial real estate market, curtain walls are increasingly standard for new office buildings, banks, hospitals, hotels, and high-end retail. Tenants expect natural light, views, and modern aesthetics. Building owners value the durability, low maintenance, and energy performance (when specified with insulated glass units and thermal breaks). ACCO’s approach integrates architectural engineering principles with interior design goals – the facade is not just an exterior cladding; it is a critical interface that affects interior daylighting, thermal comfort, acoustic privacy, and views.

Key curtain wall systems ACCO works with include: unitized curtain wall (pre-assembled panels fabricated off-site for fast installation – ideal for high-rise buildings), stick-built curtain wall (framing and glass assembled on-site – more flexible for complex geometries), structural glazing (glass bonded to the frame with structural silicone – seamless appearance), point-supported glass (glass held by stainless steel spider fittings – minimal framing, maximum transparency), and double-skin facades (two glass layers with ventilated cavity – superior thermal and acoustic performance). ACCO also provides ACP cladding, glass and aluminium railing systems, and interior glass partitions as related services. Across Pakistan, from DHA commercial developments to Gulberg corporate towers, Curtain Wall & Facade Interiors services in Pakistan define modern architecture.

ACCO: 25+ Years of Facade Engineering Excellence

Ahmed Construction Company (ACCO) has been designing and installing curtain wall systems for over 25 years. From our Lahore headquarters at Office 2, 3rd Floor, Bigcity Plaza, Gulberg-III, and our Karachi office, we have completed numerous facade projects for commercial, corporate, and institutional clients. Our notable clients – Meezan Bank (multiple branches with signature glass facades), Bata (storefront glazing), and BUITMS (campus building facades) – trust us for quality and performance.

What makes ACCO uniquely qualified for curtain wall and facade work is our multi-disciplinary engineering capability. Curtain walls require structural engineering (wind load calculations, seismic movement accommodation, dead load transfer), thermal engineering (condensation resistance, U-value calculations, thermal break design), water management (pressure equalization, drainage, sealant specifications), and integration with building MEP systems (lighting, HVAC, fire safety). ACCO’s team includes structural engineers, facade specialists, and MEP engineers – all working together. We also provide architectural drafting and 3D architectural walkthrough for facade visualization before fabrication begins.

Our geographic coverage includes all major Pakistani cities: DHA (Lahore, Karachi, Islamabad), Bahria Town commercial zones, Gulberg, and corporate districts nationwide. We also serve international clients in the UAE, UK, Saudi Arabia, Canada, and USA. When you choose ACCO for Curtain Wall & Facade Interiors services in Pakistan, you get facades that are beautiful, weathertight, thermally efficient, and engineered to last.

Our Complete Curtain Wall & Facade Service Categories

ACCO offers specialized curtain wall and facade solutions for every building type. Each service leverages our architectural engineering expertise and facade fabrication capabilities.

1. Unitized Curtain Wall Systems

Pre-fabricated, pre-glazed curtain wall panels manufactured in factory conditions and shipped to site for rapid installation. ACCO provides: structural engineering (wind load, seismic, dead load), thermal engineering (thermal breaks to prevent condensation, U-value calculation), water management (double weather seals, pressure equalization chambers), aluminium framing (extruded to custom profiles, powder-coated or anodized), glass specification (insulated glass units with low-E coating, argon fill, laminated for safety), and installation engineering (anchor systems, floor slab connections, maintenance access). Ideal for: High-rise commercial towers where on-site assembly time is critical (2-3 floors per day).

2. Stick-Built Curtain Wall Systems

Site-assembled curtain wall where framing, glass, and panels are installed piece by piece. ACCO provides: shop drawings for every component, aluminium extrusion supply, glass cutting and fabrication, sealed unit assembly, thermal break specification, gasket and sealant selection, and on-site installation supervision. Stick-built allows more flexibility for complex geometries, curves, and transitions. Ideal for: Low to mid-rise buildings, complex-shaped facades, and projects where unitized logistics are challenging.

3. Structural Glazing & Spider Glass Systems

For maximum transparency, structural glazing systems use structural silicone to bond glass to the frame (no visible caps) or spider fittings (stainless steel points) to hold glass panels. ACCO provides: glass specification (tempered or laminated, appropriate thickness for spans), hardware engineering (spider fittings, tension cables for cable-net facades), structural calculations (glass strength under wind and snow loads), installation sequencing, and sealant specification (structural silicone compatibility). Learn more about our architectural engineering approach to complex glass structural systems.

4. Aluminium Composite Panel (ACP) & Metal Facades

Where glass is not appropriate (for solar control, privacy, or aesthetic contrast), ACP and metal panels provide a modern, durable facade. ACCO provides: panel engineering (sub-construction of aluminium or steel framing, panel attachment methods), material specification (3mm or 4mm ACP with PVDF coating, perforated metal panels, standing seam metal panels), installation drawings, and finishes (custom colours to match brand or architectural palette). ACP facades are ideal for spandrel areas between vision glass, column covers, and parapet cladding.

5. Interior Glass Partitions & Structural Glazing (For Interior Facades)

Curtain wall principles also apply inside buildings. ACCO designs and installs interior glass partitions that echo exterior curtain walls: full-height glass walls for offices, atriums, and lobbies; interior structural glazing for showrooms; and frameless glass railings for mezzanines and staircases. These interior glass facades maintain visual connection while providing acoustic separation and fire-rated options where required. Complement our Space Planning & Layout Design services in Pakistan with interior glass facades.

6. Facade-Integrated LED Lighting & Media Facades

Transform your curtain wall into a nighttime landmark. ACCO integrates LED lighting systems into curtain wall framing: linear LED profiles mounted in mullions, back-lit glass panels, point-source LED for media facades (full video display), and dynamic colour control systems. We coordinate electrical connections (low voltage, waterproof, accessible for maintenance) and thermal management (LED heat can affect glass and seals).

7. Facade Engineering & BIM Modeling

Complex curtain walls require advanced digital coordination. ACCO uses BIM Modeling (explore our BIM Modeling services) to design every component: mullion and transom intersections, anchor points to building structure, interface with slab edges, integration with floor-to-ceiling interior partition walls, coordination with MEP (HVAC diffusers, sprinklers, light fixtures that must align with 600mm module), and clash detection between facade and building systems.

ACCO vs. Glass & Aluminium Contractors: Why Choose a Full-Service Firm

Not all glass installations are engineered facades. Here is why ACCO’s Curtain Wall & Facade Interiors services in Pakistan deliver superior performance.

Our Curtain Wall & Facade Project Process

ACCO follows a rigorous, engineered process for every Curtain Wall & Facade Interiors services in Pakistan project. Precision is everything – a 1mm error at the top of a 10-storey building means the facade does not fit.

1. Free Consultation & Feasibility Study: We discuss your building type, desired aesthetic (full glass, punched windows, mixed material), performance requirements (thermal, acoustic, wind resistance), and budget. We advise on feasible systems: unitized, stick-built, structural glazing, or combinations.
2. Architectural & Structural Interface: We review building architect’s drawings and structural engineer’s slab edge locations. We identify anchor points and interface conditions. If needed, we provide architectural drafting showing facade-to-structure connections.
3. Detailed Facade Engineering: Our structural engineers calculate: wind loads (based on building height, location, and local wind speed data), seismic accommodation (movement joints, slotted connections), dead load transfers, thermal expansion (aluminium expands/contracts significantly with temperature), and condensation analysis (to prevent water on interior glass surfaces).
4. Curtain Wall Design & 3D Visualization: We produce elevation drawings showing every glass panel (dimensions, glass type), every mullion and transom (profile sizes, finishes), and anchor point locations. We build a 3D architectural walkthrough so you see the facade from inside and outside – including how light enters the interior.
5. BIM Modeling & Coordination: We create a detailed BIM model integrating the curtain wall with building structure, MEP systems (HVAC diffusers must align with curtain wall module), interior partitions (floor-to-ceiling glass interiors align with mullion centers), and other facade elements (louvers, sunshades, spandrel panels).
6. Fabrication Drawings & Material Procurement: We produce shop drawings for every component: aluminium extrusions (cut lengths, corner cuts, gasket grooves), glass panels (sizes, edgework, hole locations for spider fittings), anchors and brackets (materials, welding specifications, bolt grades). We procure materials from trusted suppliers (locally and internationally).
7. Mock-up & Testing (For Critical Projects): For large or high-performance projects, ACCO recommends a full-scale curtain wall mock-up (one module). We install it at the factory or a test facility and perform: water penetration test (ASTM E1105, no leaks), air infiltration test (ASTM E283), structural load test (ASTM E330), and thermal cycling (freeze-thaw if applicable). The mock-up is approved before full fabrication begins.
8. Fabrication & Quality Control: Unitized panels are assembled in factory conditions (climate-controlled, dust-free). We inspect every panel: extrusions for damage, glass for scratches, sealant for continuity, hardware for torque. Stored panels are racked vertically to prevent distortion.
9. Site Installation & Sealing: Our certified installation team installs anchors, lifts panels into place (using cranes, boom lifts, or human lift for lower floors), aligns and secures to anchors, installs internal gaskets and seals, and applies field sealant (carefully tooled to ensure adhesion and weathertightness).
10. Final Inspection, Cleaning & Handover: We inspect every joint and seal. We clean glass (removing labels, manufacturing residue, and construction dust). We test a sample of windows for operation (where operable windows are included). We provide O&M manuals (cleaning recommendations, hardware replacement part numbers, sealant maintenance schedule).

Why Pakistani Building Owners & Developers Choose ACCO

Pakistan’s commercial real estate market is transforming. New buildings in DHA Lahore, Bahria Town Karachi, and Islamabad’s Blue Area compete for premium tenants. The buildings with curtain wall facades win. They look more prestigious. They offer better daylight – studies show employees are 15% more productive in daylit offices. They have higher resale values. They command higher rents.

Building owners choose ACCO because we deliver facades that perform. No leaks. No condensation drips on expensive interiors. No failed seals after one monsoon season. No drafts. Our engineering background means we design for Pakistan’s specific conditions: high wind loads in coastal Karachi, significant seismic risk across northern Pakistan, and intense solar heat gain (low-E glass and shading are essential).

Frequently Asked Questions About Curtain Wall & Facade Interiors in Pakistan

1. What is architectural engineering and why does my curtain wall need it?

Architectural engineering applies engineering principles to building design. For curtain walls, this means wind load calculations (a 10-storey building experiences much higher wind pressures than ground level), seismic movement accommodation (Pakistan is seismically active), thermal engineering (to prevent condensation and heat loss), and water management (monsoon rains can penetrate poor designs). Without architectural engineering, curtain walls leak, crack, or fail. ACCO’s engineers ensure performance.

2. How do I get a floor plan that integrates with my curtain wall design?

Contact ACCO via phone (+92 322 800 0190), email (info@acco.com.pk), or our Contact Us page. For new buildings, ACCO can provide architectural drafting for the entire building, coordinating facade design with home floor plan (or commercial floor plan) layout. For existing buildings retrofitting curtain walls, we survey the building and create interface drawings.

3. What is the difference between a curtain wall and a storefront window system?

Curtain walls are engineered to span multiple floors, accommodate building movement (wind sway, seismic, thermal expansion), and resist water penetration under high wind pressures. They are typically tested to ASTM standards. Storefront window systems are designed for single-floor applications (retail stores, ground-floor offices) and are not engineered for high-rise wind or movement. ACCO provides both – but for high-rise, you need a true curtain wall.

4. Do you provide 3D walkthroughs showing how the facade looks from inside?

Absolutely. Every facade project includes a 3D architectural walkthrough showing both exterior appearance and interior views. You see exactly how much natural light enters, where mullions obstruct views, and how the facade frames the exterior. This visualization is essential for clients – curtain walls are expensive, and you need to approve the look before fabrication.

5. Can ACCO design curtain walls for commercial plazas and hospitals?

Yes. ACCO has extensive experience with facades for commercial, healthcare, retail, and institutional buildings. Hospitals have specific glass requirements (e.g., bird-friendly glass, antimicrobial coatings for certain areas). Commercial plazas need durable, low-maintenance facades accessible for cleaning. We adapt our curtain wall solutions accordingly. Learn more about our engineering capabilities for different building types.

6. How long does a curtain wall project take from design to installation?

Timelines vary dramatically by scale. A ground-floor retail facade (storefront) takes 4-6 weeks from order to installation. A 10-storey unitized curtain wall for a commercial tower takes 6-9 months: 2-3 months for engineering and shop drawings, 2-3 months for fabrication, 2-3 months for site installation (about 1-2 floors per week). ACCO provides detailed schedules during the consultation phase.

7. What glass is best for a commercial building in Karachi (hot, humid, coastal)?

For Karachi’s climate, ACCO recommends: insulated glass units (double pane) with low-E coating on the #2 surface (reduces solar heat gain), argon gas fill (improves insulation), and a solar control coating (lower solar heat gain coefficient, SHGC). For coastal humidity, ensure outer pane is tempered for windborne debris resistance, and use laminated glass for overhead or fall-hazard areas. ACCO will calculate specific values based on building orientation and window-to-wall ratio.

8. How much do curtain wall and facade services cost in Pakistan?

Costs vary dramatically by system type, glass specification, building height, and complexity. Basic storefront glazing (non-engineered, single-glazed): PKR 6,000-10,000 per square meter. Basic stick-built curtain wall (thermally broken, double-glazed): PKR 12,000-20,000 per square meter. Unitized curtain wall (high-performance, engineered): PKR 20,000-40,000 per square meter. Premium systems with custom finishes, high-performance glass, or complex geometries cost more. Contact ACCO for a detailed quote based on your specific project.
