Although in theory skylight allows greater light transmittance values comparing with wall windows, real-life usage reveals them largely dependent on the characteristics of roof windows. Improper selection of space for roof windows may result in dark and dreary illumination. The main rule when mapping both light system and the dissemination of light is that in the room you leave at least 7-10 % of floor space to the window area for light to penetrate. Thus, the skylights that are to be mounted in the attic bedroom, guest room or bathroom are made to be smaller. However, if the children or necessity of making living room lighter, are your concerns then you may want to either install a few windows or opt for larger dimensions.
Sometimes, even though dimensions of roof windows and the number of them to be installed, are set correctly, the height at which they are placed still can be subject for the most common mistake, that is, too much of it. In this case negatyve impact on perception of the space and light is rather palpable. To figure out the best configuration you should position. the upper frame at about 2 meters above the floor. It’s easy to show why skylights do not just lead to the perfect interior and better light transmittance as. their design is extremely user-friendly and the mechanism is incredibly smooth to operate.
The last thing not to be unmentioned is the build quality. Poor quality skylights start sweating not long after being installed with humidity level rising and being exposed to the sun, rain, snow etc.
