Glass Wall Systems (India) Limited

Sector: Building Materials & Construction / Façade Engineering Solutions (Manufacturing + EPC + Fenestration)

1. Overview

Glass Wall Systems (India) Limited ("GWS") is a premium façade solutions and fenestration provider operating across India, the USA and Australia. Founded in 2002 as a partnership firm by Jawahar Hariram Hemrajani and Kamlesh Arjunlal Chaudhari, GWS ranks as the second largest provider of façade solutions in India in terms of revenue in Fiscal 2025 and Fiscal 2024, and is India's largest façade exporter in 2024 (Source: Ken Report). As of March 31, 2026, the Company has successfully completed 158 projects.

The Company operates a hybrid, vertically integrated business model with three verticals — Domestic Façade Solutions (EPC), International Façade Products Supply and (post-acquisition of Yes Systems in August 2025) Luxury Fenestration. All manufacturing is anchored at its Vile Bhagad Facility in Raigad, Maharashtra (101,299 sq m land parcel; 32,415 sq m developed; post-expansion capacity of 130 panels per day; four dedicated production lines), strategically located ~100 km from the Nhava Sheva port for export logistics. GWS has a strong domestic client roster including Bagmane, K Raheja, Prestige, Embassy and Lodha, with several relationships spanning 8–12 years.

Total order book across verticals stood at ₹981.5 Cr as of July 31, 2026.

Competitively, GWS is positioned as the only Indian company with such extensive vertically-integrated operations (Source: Ken Report) covering design, manufacturing, and project management — a moat further reinforced by the planned in-house Glass Processing Unit (GPU) capex of ₹50 Cr funded from the Fresh Issue.

Contract & Pricing Models

• Domestic Façade Solutions: primarily EPC contracts for real estate developers, hospitals, airport authorities, general contractors and corporate clients — covers design, engineering, fabrication, supply and installation. The Company has strategically shifted focus to commercial projects (shorter execution timelines, escalation clauses, favourable payment terms). Contracts now increasingly incorporate escalation clauses to hedge raw material price volatility.
• International Façade Products Supply: B2B product supply to façade contracting companies (primarily RWW and Winpro in the USA, SRG Global in Australia) — GWS supplies fully unitized and fabricated curtain wall panels; installation is performed by the overseas contractor. This model has higher realizations per square foot, lower working capital requirements and minimal on-site risk, making it materially margin-accretive.
• Fenestration Solutions (Yes Systems / 'ORIA'): direct sales to luxury residential developers and high-net-worth individuals; bespoke, custom-engineered systems including proprietary in-house brand 'Bella Vista' and partnerships with premium international brands LIBART, OIKOS and a leading premium Swiss window systems brand.

Client & Vendor Concentration (Key Risk Metrics)

• Top 10 clients: contributed 86.40% / 78.13% / 88.56% of revenue from operations in FY26 / FY25 / FY24 respectively — high concentration. FY26 top clients include Winpro International LLC, Bagmane Constructions and Reflection Window+Wall LLC.
• Top 10 suppliers: accounted for 69.54% / 65.25% / 64.12% of raw material cost — key suppliers include Global Aluminium, Dow Chemical International, Hindalco, FG Glass Industries, Steelloys India, Angel's Aluminium Corporation. GWS does not enter into long-term supply contracts.
• State concentration: Maharashtra and Karnataka together accounted for ~44.6% (FY26) of revenue.

4. Key Business Strengths

• Market leadership with diversified verticals — 2nd largest domestic façade provider (Ken Report) and India's largest façade exporter in 2024; three revenue verticals balancing EPC (domestic), high-margin product supply (international) and luxury fenestration (post-acquisition).
• Marquee client base with 8–12-year relationships — 22 domestic and 5 international active clients as of March 31, 2026; repeat business from Embassy, Lodha, Bagmane, Prestige, K Raheja domestically and RWW, Winpro, SRG Global internationally.
• Strategically located, vertically-integrated manufacturing — 32,415 sq m developed facility ~100 km from Nhava Sheva port; only Indian company (per Ken Report) with such extensive integrated operations spanning design, manufacture, and project management.
• Sustainability leadership as a competitive moat — exclusive tie-up with Dow Corning for low-carbon and carbon-neutral silicone; low-carbon aluminium from Global Aluminium; rooftop solar and zero-waste program (100% aluminium scrap recycling); EPD-certified products supporting client LEED / IGBC objectives.
• Experienced promoter-led leadership — Jawahar Hariram Hemrajani (~34 years in façade industry) and Eshan Jawahar Hemrajani (~12 years; Cardiff engineering, Warwick MSc); backed since 2014 by MO Alternate Investment Advisors (Motilal Oswal's PE arm).
• Design & engineering-led differentiation — 46+ designer team using AutoCAD, STAAD, HiCAD; in-house testing rig; industry-leading solutions such as diagrid systems, cold profile bending for curved unitized panels, electrochromic façade execution.
• Export-tailwind positioning — India's China+1 advantage combined with 'Make in India' momentum; overseas revenue grew at 25.08% CAGR from ₹132.03 Cr (FY24) to ₹206.57 Cr (FY26); "Designated Export Place" status at Vile Bhagad enables direct-from-factory customs clearance.

5. Future Growth Strategy

• Strategic global expansion beyond USA and Australia — targeting entry into Canada and European Union (Germany, France, Italy, Spain, UK); leveraging track record in USA/Australia to build local partnerships; participation in trade shows already generating enquiries; global façade TAM projected at USD 30,544 million by 2030.
• Deepen domestic leadership by selective, high-quality project bidding — pursuing projects with financial credibility, favourable payment terms, shorter turnarounds; expanding into high-growth verticals such as data centres and hospitals; TAM for Indian façade + fenestration estimated at ₹29,350 Cr in FY26, projected to reach ₹45,930 Cr by FY30.
• Scale luxury fenestration via full Yes Systems integration — capitalize on Indian ultra-luxury residential fenestration market growing at 24.4% CAGR (₹260 Cr FY20 → ₹970 Cr FY26 → ₹2,090 Cr FY30E); expand 'ORIA' brand with LIBART, OIKOS and Bella Vista offerings.
• Capacity expansion + backward integration via GPU Project — planned 33% increase in manufacturing capacity; ₹50 Cr Fresh Issue capex to set up an in-house Glass Processing Unit at Vile Bhagad (operational by ~August 2027) — glass is 24–32% of raw material cost, so backward integration is expected to reduce leakage of margin to third-party suppliers and substantially offset the incremental depreciation through cost savings.
• Enhance contractual protections and derisking — increased use of escalation clauses in long-term contracts to hedge raw material volatility; strategic project selection with financially stable developers.
• Technological advancement and in-house testing — leverage advanced software (AutoCAD, STAAD, HiCAD), 3D printing for prototyping, and an in-house testing rig to drive quality differentiation, reduce on-site defects, and enhance client trust.
