Benefits of timber-aluminium clad windows

Timber-aluminium clad windows are chosen for premium projects for one simple reason: they deliver visual and tactile comfort inside while preserving flawless appearance outside over time.

Interior wood brings warmth and a home feeling. Instantly changes perception of space: warm, natural, matches parquet, doors, furniture and high-end decor.
Exterior aluminium delivers protection and durable colour. Cladding protects window from rain, sun, temperature variations. Stable look, minimal maintenance, clean facade for years.
Good thermal performance, especially with triple glazing. For NZEB, passive house or large glazing, triple glazing is usually the logical choice (with correct sealing + install).
Configurable acoustic comfort. In traffic/busy/noisy areas, glass package matters enormously — pick by dB based on real noise source.
Sealing and system stability. In premium windows, sealing and rigidity show in use: no drafts, no play over time, no compromise on large elements.
Premium security (RC2/RC3). Safety glass and anti-burglary packages based on positioning (ground floor, yard access, low windows).

Configurations for timber-aluminium windows

Timber-aluminium windows are a system: profile, glass, spacer, hardware, install. The right configuration follows project, exposure, noise, security and style.

Glass and glazing

Double / triple glazing: double can be enough for standard; in premium, NZEB, passive house, triple is the right choice (especially for large glazing).
Acoustic options: for traffic and busy zones, pick by noise source (performance = dB per package).
Safety glass (ESG / VSG): for low/ground-floor/exposed windows. ESG (tempered, controlled breakage), VSG (laminated, shards stay on film).
Warm-edge spacer: reduces edge thermal bridges + condensation risk.

Interior wood / exterior aluminium shades

Interior: natural shades, stains and finishes that easily match parquet and furniture.
Exterior: aluminium colours in standard variants and extended RAL palette when needed.
Real samples in showroom — decisions are easier with finishes seen in real light before ordering.
For comparison, in projects wanting metallic exterior but easy-maintenance interior, an alternative is PVC-aluminium windows.
