Home Product Explorer (D-039): the three category cards are selectors — they change the products below without leaving Home. No category-level "Bekijk alle …" link on Home (category pages stay reachable from the nav of other pages). Products shown are for testing only; live = published products only (OQ-024). Doors: all 29 client-confirmed models in a model browser (D-055); ranges 01–10 / 11–20 / 21–29 are navigation only — no invented door families. TO VERIFY values left out; NEO coefficient pending (OQ-037). Kozijnen: Product Focus Hub — MEER BEKIJKEN opens the product inline (gallery + Overzicht / Technische gegevens / Eigenschappen / Documenten + Offerte aanvragen), INKLAPPEN restores the carousel; switching category resets it. Content not final (RM-PCC). Schuifpuien: Product Focus Hub with the two primary systems; SMART-SLIDE NEO as secondary alternative (D-045). Sliding images = client docx renders, mapping TO VERIFY (OQ-018). No autoplay, no loop.

Frequently asked questions

Good to know.

Every home and every project is different. That is why we like to work out the best solution together.

  1. Yes. You don't need to know in advance which system or version you need.

    Tell us what you would like to change, what matters to you and what you already know about the property. Based on that, we will look for a suitable solution and version together.

    Feel free to contact us for personal advice.

  2. Not always. Even if not all measurements are known yet, we can already discuss your request with you.

    For a final order, the correct dimensions naturally need to be established accurately. Visterra can help by measuring the situation on site.

    Feel free to send a request with the information you have now.

  3. Yes. Visterra supplies products both with and without installation.

    If you choose installation, we can include the removal of the existing elements, the fitting and the interior and exterior finishing in the proposal. We agree the exact work and options with you for each project.

    Feel free to request a quote that suits your situation.

  4. The typical lead time is around 8–13 weeks from the order. This is an indication, not a guarantee: the lead time depends on the product, the configuration, the project and the manufacturer's schedule.

    With your quote, we can discuss the current expected timeline for your project.

  5. Visterra currently carries out installation mainly in South Holland, North Holland and North Brabant.

    Do you live outside these provinces? Feel free to contact us and we will look at the options together.

    Delivery to Belgium is possible; we do not currently carry out installation there.
