Window sills are more than just places to keep plants or pictures. On the outside of your home, window sills can serve a number of purposes. One of the main functions of exterior window sills is to divert rain water away from the facade. Otherwise, water and dirt would slowly damage the walls over time and leave them looking dirty and stained.
Thus, exterior window sills are fitted with a special edge, slanted in a way to keep water draining away from the house. Of course, they can also be used to place items on such as potted plants or to accent your home’s appearance.
There are many differences between the countless window sills on the market today. For window sills on the exterior of the home, the amount of space available is important to note. If the house has walls that are thicker than usual, then it may be necessary to have the windows sills custom made to fit if standard sizes are incompatible.
Additionally, they can also differ based on your personal tastes, selection of material, and budget. Modern exterior window sills mostly use aluminum, but the following materials can also be used:
These materials differ from each other not just in their appearance, but also in terms of the properties of each and how they relate to your specific needs.
Product lifetime and required upkeep are perhaps the most important points. Aluminum window sills for example, have a longer lifetime than wood which also requires recoating every five years.
A third difference between the various window sills is the shape or design. Exterior window sills are fitted with a drip edge. The edge itself presents a characteristic appearance and should, therefore, be specially chosen to blend in with the rest of the facade. The most commonly found edgings are:
Naturally this is not an exhaustive list of every possible variation you can find today. One point to note is that not every type of edge is possible with every material. Edging with raised sides, for example, is only offered with stone sills. Similarly, the stepped and rounded edge model is for wood and aluminum only.
Your final choice of material for your external window sills will of course bring certain advantages and disadvantages with it regarding things such as durability and maintenance. Aluminum is by far the easiest in these two aspects and requires only a quick wipe down from time to time in order to keep them looking good.
One of the down sides of most window sills is that they typically cannot be installed without professional help. Therefore, it is usually necessary to have a craftsman fit and install them to ensure they sit correctly and securely.
