How to choose PVC windows

Choosing PVC windows means accounting for project starting state, final state and all factors that affect configuration.

By project type

Residential, full renovation. Sills, insulation, positioning and sealing matter. A good PVC window loses performance with sloppy install.
New builds, NZEB, passive house. Usually we recommend triple-glazed PVC joinery with professional install focused on sealing continuity and thermal-bridge reduction.
Developers, multi-window projects. Predictability is key: repeatable config, consistent install logic. Often PVC-aluminium windows for extra resistance.

By design

Frame-to-glazing ratio.
Profile colour and texture.
Glass type (clear, frosted, decorative).
Hardware and opening mode. Made-to-order PVC windows suit projects with architect/designer control. Architects often choose wood-aluminium.

By location

Wind and rain. Sealing and rigidity matter — the gap between ok and premium shows over time.
Traffic and noise. Glass packages focused on acoustic insulation. In the city, real comfort = silence, not just temperature.
Security. Ground-floor or easily-accessed PVC windows → put security on the list from start: RC2, RC3, safety glass and correct hardware.

PVC windows — performance and configurations

PVC windows are a system: profile, glass package, spacer, hardware, installation. If one piece is wrong, the result drops.

Double glazing (2 panes) works for standard projects and balanced budgets. Triple glazing (3 panes) is the frequent recommendation for premium, NZEB and passive house — especially with large glazing or exposed orientations. PVC triple glazing without correct perimeter sealing loses its advantage — so we treat installation as part of performance.

Acoustic comfort

Heavy traffic, boulevards, trams or noisy neighbours → glass configuration matters more than frame choice. We discuss your real scenario and recommend glass based on noise source and window position.

Security

We configure RC2 (standard, resists manual attacks with basic tools) and RC3 for certain systems. Safety glass: ESG (tempered, small fragments on breakage) or VSG (laminated, shards stay on inner film).

Details that matter

Warm-edge spacer between glass panes → reduces edge thermal bridges and condensation risk. Decorative glass (frosted, etched, sandblasted) — for bathroom, dressing room or privacy zones without losing light.

PVC joinery colours and finishes

PVC joinery colours from our partners cover most design requirements. PVC windows configure in a vast palette — about 19 interior colours and 49 exterior colours.

Colours and decorative foils

White — for bright interiors.
Wood-look textures — warm, classic or Mediterranean homes.
Dark shades — contemporary architecture, especially contrast against facade.
Common requests: walnut, golden oak, mahogany, brown, black. Tip: pick colour by natural light, not screen — see real samples in showroom.

Extended RAL palette

If the project calls for a very specific palette or exterior colour matching the facade, discuss all specifications with a consultant.

Measurements — openings, positioning, install details.
Quoting — clear offer with options and recommendations.
Made-to-order production and planning.
Installation, adjustments, final check — clean and controlled, sealing focus.

FAQ

Frequently asked questions about PVC windows

It depends on the configuration. The glass package, spacer and installation all matter. For noisy areas, the choice starts from acoustics.

Depending on the model, you can choose fixed, tilt-and-turn or casement windows, plus ventilation options. The configuration is decided based on opening size and how you use the room.

Our suppliers provide a wide range of colours and decorative films for PVC joinery: light shades, white, wood finishes (walnut, golden oak, mahogany) and dark shades depending on the project.

In premium, NZEB and passive house projects, the recommendation is usually triple glazing. Double glazing is fine for standard projects if installation and sealing are done correctly.
