Ikkunarakenne

Ikkunarakenne refers to the structural framework of a window. This encompasses all the components that hold the glass in place and allow the window to be installed into a building. Key elements include the frame, which is the outer part that attaches to the wall, and the sash, which holds the glass and can often be opened or closed. The frame itself is typically made of materials like wood, vinyl (PVC), aluminum, or composite materials.

Within the frame, there are usually internal divisions called muntins or glazing bars that can create smaller panes of glass, or the entire sash might hold a single large pane. The method of opening and closing a window also influences its ikkunarakenne. For example, a casement window has a sash that swings outward on hinges, while a double-hung window has sashes that slide vertically.

The ikkunarakenne is crucial for a window's functionality, affecting its insulation properties, durability, security, and aesthetic appearance. Proper design and construction of the ikkunarakenne ensure that the window is weather-tight, preventing drafts and water ingress, while also providing structural integrity. The choice of materials and the complexity of the design can significantly impact the cost and maintenance requirements of the window. In modern construction, attention is paid to the thermal performance of the ikkunarakenne to improve energy efficiency.
