What kinds of window sills are there? What is the fundamental difference between them? Which one is better to choose? Are there any hidden points that are difficult to predict in advance? Any information will be gratefully accepted
It is a building element that is placed at the bottom of the windows within certain dimensions or molds during the construction phase and serves to prevent possible deformations of snow and rainwater. Sills, which are manufactured in different types according to the type of material it is produced, have both decorative and functional features. The construction world has also joined the changing and developing technology and different manufacturing techniques have been developed using these innovations. Sills with the desired features are manufactured with various production methods.
Windowsills need to be produced in different specifications according to the character and service purpose of the building. For example, while steel profiles are manufactured in factory, shop or industrial type buildings, marble windowsills are much more preferred in residential buildings. If the sill is not designed according to the characteristic features of the building, it cannot fully fulfill its task and leads to deformations in the structure over time.
The windowsill consists of two parts, the windowsill and the inner windowsill. One part is located on the inside of the structure and the other part is located outside. While the inner part is mostly used for decorative purposes, the outer sill is in direct contact with external influences such as rain and snow water. The windowsills are made 3.5-4 cm inside the wall surface. The outer windowsills should also be produced with a dropper made of waterproof materials. The dropper is a 2-3 mm wide part that allows the water accumulated on the windowsill to be safely removed.
The windowsills should be produced with a certain slope so that the water to be drained can easily accumulate in the droppers. Rainwater flowing from the joinery surface is transmitted away from the facade through this gap. When manufacturing the windowsill, a 5% slope is given and it is inserted under the joinery by 2 cm. The missing small gaps are filled with silicone putty.
Types of window sills are divided according to the material from which they are made:
- Marble windowsills
- Wooden windowsills
- Concrete sills
- PVC windowsills
- Natural stone windowsills
- Brick windowsills
- Polyurethane windowsills
Marble Windowsills: Marble is a very frequently used building material in the construction of windowsills. The biggest reason for this is its resistance to water. It provides drainage easily with its hard and gapless structure. Moreover, it is very effective against UV rays and dust.
Wooden Windowsills: Wooden windowsills are produced in different tones and shapes. In general, it provides drainage together with the surface coating. The surface coating prevents water from entering the wooden windowsill. It is suitable for use for wooden structures.
Concrete Windowsills: It is prepared in the dimensions determined for each window and made ready for use with on-site mold and casting.
PVC Windowsills: The raw material is PVC and it is the most widely used type of sill in the market.
Natural Stone Windowsills: Natural stone windowsills stand out with their decorative appearance.
Brick Windowsills: Brick windowsills are applied to the space under the window while the wall is being built.
Polyurethane Windowsills: It is an insulation material with high resistance against external factors such as heat and sound.
