Built for one of Europe’s most demanding construction markets.

NLS has completed and continues to deliver technically demanding window packages across Germany.

Our experience covers thermal and acoustic requirements, safety glazing, sun-shading interfaces, production drawings, logistics and installation coordination. We apply the same technical discipline to every international supply order.

From specification to site reality

We know what happens after the purchase order.

Our project experience shapes how we review drawings, clarify interfaces, define glazing and hardware, coordinate production, pack positions and communicate changes before they become site problems.

  • Technical review before production
  • Position-based documentation and packing
  • Practical understanding of installation interfaces
  • German-side commercial and technical accountability

PVC-U window platforms

German systems. Configured around the project.

System, glazing, reinforcement, hardware, colour and performance are specified around the actual requirement. The figures below are system capabilities; final element performance depends on size, glazing and configuration.

Glass & facade-side components

Buy the window. Buy the glass. Or build a complete supply package.

We can quote finished windows or selected components separately. This allows distributors and contractors to compare a complete delivered scope instead of isolated factory prices.

Glass & IGU · glass-only supply available

Performance glazing configured to the specification.

Low-E, solar-control, safety, acoustic and thermal requirements can be combined into project-specific double or triple insulating glass units. Laminated and tempered build-ups can be specified where safety or fall-protection requirements apply.

Window and sun-shading interfaces can be coordinated as one package, including guide rails, box conditions, electrical interfaces and project-specific details. WAREMA solutions can be included where specified.

Facade components

Aluminium exterior window sills

Cut-to-size aluminium exterior sills and accessories can be supplied with the window package or quoted separately.

OEM / private label

Your market. Your brand. Controlled supply.

For repeat distributors, production specification, labelling, packing and documentation can be structured around an agreed private-label workflow.

How we work

Start with a real benchmark. Grow from there.

We do not ask a distributor to replace an established supplier on day one. NLS is designed to become a technically reliable second source first — then earn repeat business through quality, communication and delivery performance.

01

Supply only

Made-to-order finished windows for distributors, installers and resellers — packed for onward delivery or installation.

02

Project supply

Technical review, configuration, production coordination and project-oriented logistics for defined construction packages.

03

OEM / private label

A controlled product specification and repeat-order process for distributors building their own local market and brand.
