Right, left and top fanlight on the width of the door is an architectural or structural element often found at doors. It is a glazed area, located on the sides of the door and above it, which allows natural light to enter the room. Skylights can come in a variety of shapes and sizes, from narrow strips to larger glass panels, depending on design and function.

This element brings many benefits to the interior, such as:

1. Natural lighting: The right side transom effectively increases the amount of sunlight reaching the room, which can significantly improve the atmosphere and working or living conditions.

2. Feeling of space: By adding natural light, the right sidelight can visually expand the room, giving it a feeling of greater spaciousness and openness.

3. Aesthetics: The right side transom can be an attractive decorative element, adding a unique charm and character to both the interior and the facade of the building.

4. Energy efficiency: Improving the amount of natural light can help reduce the need for artificial lighting during the day, which contributes to energy savings.

Skylights can be used in a variety of contexts, from residential homes to commercial buildings, contributing to functionality, aesthetics and user comfort.
