PVC-aluminium windows

PVC-aluminium windows are the right choice when you want premium joinery with good insulation and an exterior that holds up impeccably over time. You combine two materials: PVC for thermal comfort and moisture stability, aluminium on the outside for protection, durable colour and minimal maintenance. At Kulttur we work with Internorm windows on projects where details matter: new builds, full renovations, modern facades and projects with clear energy efficiency requirements, including NZEB. All made to order: dimensions, colours, accessories, handles, security level, plus solar protection and privacy options.

Why PVC-aluminium in premium projects?

PVC-aluminium joinery has a simple goal: comfort inside, resilience outside, without complicated maintenance.

PVC contributes to thermal insulation and stability in high-humidity environments. Exterior aluminium protects the window from weather, preserving look and colour for years. In a premium project = fewer compromises, fewer worries.

When it's the right fit

  • New builds and full renovations — a system that looks good and runs stably over time.
  • Exposed facades to wind, rain, sun — exterior must hold up flawlessly.
  • Multi-window projects — predictable configuration and install.
  • Modern architecture — exterior colour and joinery details matter.
  • Energy-efficient projects — triple glazing + careful sealing install.

When it's not the right fit

  • Standard project with budget priority → sometimes start with plain PVC windows.
  • You explicitly want wood inside, with natural look and comfort feel → natural direction = wood-aluminium.
  • Special architecture (extreme dimensions, atypical solutions) → project-detail decision with consultant.

Recommended PVC-aluminium window configurations

PVC-aluminium windows aren't just profile + glass — they're a system. Real performance comes from the right combination of glazing, spacer, hardware, accessories and install.

Consultancy, measuring, installation & service

The most common mistake with PVC-aluminium joinery is treating the window as a product, not a system. In successful projects, installation and surrounding details matter as much as the chosen model.

  • Initial talk — project, style, exposure, noise, security, colours.
  • Configuration — fitting options with clear reasoning.
  • Measurements and detail check — opening position, sealing, thermal bridges.
  • Made-to-order production.
  • Premium install, adjustments, final check, post-install support — cuts on-site mistake risk, predictable result.

Frequently asked questions about PVC-aluminium windows

They are very resistant on the exterior due to the aluminium cladding. For special projects with extreme openings, the decision is made on system detail and dimensions.

Yes. It is configured to order by dimensions, colours, glass package, handles, accessories, security and solar protection or privacy options.

Usually yes, because the structure uses PVC as a base. The final price depends on glass, dimensions, colours and the security level.

Yes, especially in configurations with triple glazing and correct sealing installation. In NZEB the complete system matters, not just the profile.
