Wooden window or wood-aluminum window?

Customer asks:

If the window selection includes both wooden windows and wood‑aluminum windows, how do I make the right choice, and what are the main differences between these windows?

Aru Grupp answers:

Both wooden and wood‑aluminum windows are high-quality and energy-efficient solutions. The right choice depends on the building’s location, architecture, and the amount of maintenance you are willing to do. Below, we explain the main differences and when each type of window is most suitable.

Insulation and energy efficiency

Wooden windows provide excellent thermal insulation, creating a comfortable indoor climate and helping reduce heating costs. Together with high-quality glazing, they are suitable for both new buildings and renovations.

Wood‑aluminum windows combine the thermal insulation of wood with the durability of aluminum. The interior wooden frame retains heat, while the exterior aluminum layer protects the window from weather conditions, making them ideal for modern buildings.

Durability and weather resistance

Wooden windows are durable but require regular maintenance, as wood reacts to moisture, sunlight, and temperature changes. Properly maintained wooden windows can last for decades.

Wood‑aluminum windows are particularly weather-resistant. The aluminum exterior protects the wood from rain, snow, and UV radiation, significantly reducing wear and providing long-term stability even in harsh climates.

Maintenance requirements

Wooden windows require periodic maintenance and refinishing. Wood‑aluminum windows require minimal maintenance; the aluminum coating does not need painting and retains its appearance for a long time.

Appearance and architectural suitability

Wooden windows are ideal for classic buildings, renovation projects, and heritage areas, offering a warm and traditional look.

Wood‑aluminum windows suit modern houses and apartment buildings where a clean, contemporary aesthetic is desired. The interior wood maintains a warm appearance, while the exterior aluminum provides durability and a modern look.
