Outward-opening wooden and wood-aluminium windows

Customer asks:

I want outward-opening windows for my house. Is this a good choice for the Estonian climate, and should I choose wooden or wood-aluminium windows?

Aru Grupp answers:

Outward-opening windows are very common in Nordic countries, precisely because of the challenging climate. Wind, rain, and snow don’t easily get between the frame and the sash. The window closes tightly against the seal from the outside. This keeps the window airtight and reduces heat loss, which is very important for energy efficiency. These windows are designed for Scandinavian climates. They provide good weather resistance and energy efficiency.

Outward-opening wooden and wood-aluminium windows are suitable for both houses and apartment buildings. They combine a classic look with modern insulation performance. Wood provides a natural aesthetic and excellent thermal insulation. Wood-aluminium windows add a weatherproof protective layer on the exterior. This reduces maintenance and extends the window’s lifespan. Slim profiles let more light into the room. A 60 mm frame accommodates a double-glass unit. A 78 mm frame fits a triple-glass unit, providing extra insulation and energy efficiency.

In practice, new houses often feature wood-aluminium windows. They combine the warmth of natural wood inside with durable aluminium outside. This makes them ideal for Estonia’s humid and variable climate.

Opening direction and maintenance

When planning outward-opening windows, consider maintenance and cleaning. This is especially important for windows on the second or third floor. Standard side-hinged outward-opening windows can be hard to clean from the outside.

A practical solution is a bottom-hinged or pivoting window. The sash can be rotated inward for cleaning. This makes the exterior glass safely accessible from inside. Maintenance becomes easier and safer without ladders or special equipment. This is especially useful for higher floors or buildings with frequent cleaning needs.

When designing windows, think about dimensions, materials, and opening direction. Properly chosen outward-opening windows, whether wooden or wood-aluminium, offer long service life, excellent energy efficiency, and convenient daily use for decades.
