Opening wood-aluminum windows (MSE-A)

The opening wood-aluminium windows are maintenance-free, and they can stand Finnish weather conditions. You’ll get your windows with mounted practical stays, blinds and insect screens.

Opening wood-aluminium window is the most popular window model in Finland

The opening wood-aluminium window is a sure choice practically for any situation, and that’s why it is the most popular window model in Finland. The opening structure of the window makes ventilation easy, and all the surfaces of the windows can be cleaned. In emergency situations, an opening window also acts as an escape route.

However, it is not necessary to furnish all rooms with opening windows. For example, if you want to have large and impressive picture windows in the living room, a fixed wood-aluminium window is the best choice. 

Maintenance free wood-aluminium windows remain tidy for decades

A wood-aluminium window is the best choice when excellent weather resistance is required. Thanks to the aluminium cladding of the outer sashes the window is maintenance-free, and it endures excellently northern weather conditions. Our windows are furnished with high-quality fittings and seals, and therefore they are very energy-efficient.

At our factory, we mount all the accessories you wish, such as blinds, stays and insect screens. Read more about window accessories!
