Flat Glass Subcontracting: Custom Manufacturing for
Glass Processors and Building Professionals
At Noxem Group, we support glass processors, glazing companies, façade contractors, and building industry professionals with a comprehensive range of custom flat glass subcontracting services. Our hybrid positioning — both as an international trader and a technical partner — enables us to offer competitive, reliable solutions that comply with the most demanding European standards.
We complement your production capacity by handling specific, technical, or high value-added manufacturing, including: custom tempered glass, HST tempered glass, laminated glass, glass balustrades, double glazing units, fire-rated partitions, glass roofs, and conservatory glazing.
Our objective: to help you respond to more tenders, absorb production peaks, and manage complex projects without tying up your internal resources.
Custom Tempered Glass Manufacturing
Custom tempered glass manufacturing is at the core of our subcontracting offer. We produce technical components designed for structural, decorative, and safety applications.
Tempered glass undergoes a specific heat treatment that gives it mechanical strength 4 to 5 times greater than standard float glass. In the event of breakage, it shatters into small, non-sharp fragments, ensuring optimal safety.
- Clear, extra-clear, or tinted tempered glass
- Tempered glass with processing (drilling, notches, complex cut-outs)
- Tempered glass with HST treatment (Heat Soak Test) to eliminate the risk of spontaneous breakage
- Drilling and finishing (countersunk holes, polished flat edges, etc.)
HST tempered glass is particularly recommended for façade applications, balustrades, or glass roofs, where safety is critical. This treatment significantly reduces risks related to nickel sulfide inclusions.
Examples of glass products: 10mm clear HST tempered float glass with polished edges, 12mm tempered float glass with drillings, 6mm extra-clear tempered float glass display shelves for jewelry.
We handle small to medium production runs, with dimensional precision suited to the requirements of modern construction projects.
Laminated Tempered Glass (PVB / EVA): Safety and Performance
Laminated tempered glass combines the strength of tempered glass with the safety of lamination.
Made of two or more glass panes bonded together with an interlayer (PVB or EVA), it ensures outstanding mechanical performance.
In the event of breakage, the fragments remain adhered to the interlayer film, preventing any fall of glass.
- Glass balustrades and guardrails
- Glass floors
- Glass roofs and skylights
- Facades and curtain walls
- Glass stair treads
- Laminated tempered glass 44.4, 44.6, 55.4, 66.4, 88.4, 1010.4, 1212.4
- Screen-printed laminated tempered glass (printed interlayer with custom patterns)
- Laminated tempered glass with PVB or EVA interlayers
- Opal or frosted laminated tempered glass (floor slabs or partitions)
- PVB: standard, cost-effective, suitable for most applications
- EVA: better moisture resistance, ideal for outdoor use and demanding environments
Additional options:
Acoustic interlayers (acoustic laminated glass)
Decorative interlayers (opal, colored, design finishes)
Integration of patterns or graphic elements
Manufacturing of Glass Guardrails and Balustrades
Glass guardrails are now an architectural standard in both residential and commercial buildings. They combine minimalist aesthetics, transparency, and safety.
Noxem Group manufactures custom laminated tempered glass guardrails and balustrades in compliance with current standards (DTU, NF standards, Eurocodes).
- Indoor and outdoor guardrails
- Balcony balustrades
- Terrace guardrails
- Stair railings
- Mezzanine protections
- Laminated tempered glass (types 44.2, 55.2, 66.2, 44.6, 88.4 or higher depending on structural calculations)
- Clear, extra-clear, or opal finishes
- Drilling and cut-outs for fixings
- Compatibility with clamp systems, aluminum profiles, or frameless installations
- PVB or EVA interlayers (EVA recommended for better moisture resistance outdoors)
Guardrail sizing depends on multiple parameters: height, fixing system, and applied loads.
That’s why we also offer a dedicated technical design service.
Custom Double Glazing for Windows and Facades
We manufacture custom double glazing units for window manufacturers, façade contractors, and real estate developers.
Double glazing consists of two glass panes separated by a spacer filled with gas (argon or krypton), improving both thermal and acoustic performance.
- Standard double glazing (e.g., 4/16/4)
- High-performance triple glazing
- Low-E double glazing (low emissivity)
- Solar control double glazing
- Acoustic double glazing
- Laminated double glazing for enhanced safety (44.2/16/6, 55.2/20/6, etc.)
- Spacers of various thicknesses
- Argon gas filling to improve the Ug coefficient
- Specific coatings (UV protection, anti-reflective, etc.)
- Solar control treatments (ideal for conservatories and glass roofs)
Custom double glazing is essential to meet thermal regulations (RE2020) and increasing user comfort expectations.
Fire-Resistant Glass Partitions and Technical Safety Glass
Noxem Group offers a complete range of fire-resistant glass solutions for public buildings (ERP), offices, hotels, and industrial facilities, from EI30 to EI120 ratings.
These technical glazing systems help slow the spread of flames and heat in the event of a fire while maintaining transparency.
- E: flame integrity (30 min, 60 min, 120 min)
- EW: limited thermal radiation
- EI: full thermal insulation
- Fire-rated glass partitions
- Fire-resistant glazed doors
- Internal safety façades
- Circulation areas in public buildings
These solutions are essential for meeting fire safety regulations and inspection body requirements.
Custom Glass Roofs (Verrières): Aesthetic and Performance
Glass roofs and partitions (verrières) have become a key feature of contemporary architecture. They bring natural light while structuring interior spaces.
We manufacture custom glass structures adapted to various uses.
- Interior glass partitions (industrial-style)
- Roof glazing systems
- Façade glass structures
- Commercial and office space installations
- Laminated tempered glass for maximum safety
- Option for structural laminated tempered double glazing (patios, upper floors, etc.)
- Acoustic and thermal performance options
- Transparent, opal, or decorative finishes
- Compatibility with steel or aluminum frames
Glass structures combine design and functionality, enhancing brightness and spatial value.
Conservatory Glass and Glazed Roof Systems
Conservatory glass must meet high technical requirements: mechanical strength, solar control, and thermal insulation.
We provide tailored solutions for a variety of residential and architectural projects.
- Conservatory roofs
- Glass extensions
- Bioclimatic pergolas
- Winter gardens
- Laminated tempered safety glass
- Solar control double glazing
- Low-emissivity (Low-E) glass
