Aluminium has become increasingly popular as a building material in recent years. Initially used primarily in lightweight construction, today it is also used to make windows and window sills, among other things.
The advantages are obvious: alu is stable, weatherproof and extremely easy to care for.
If you would like to equip your windows with an anthracite exterior window sill, aluminium is the ideal material.
You can also opt for natural stone such as marble, but the price is very high, so using it is usually not worthwhile. Wood and uPVC, on the other hand, are mainly used for interior window sills.
An exterior window sill made of extruded aluminium offers optimal protection against rainwater runoff. It is equipped with a so-called drip edge, which directs rain away from the masonry and thus prevents moisture and the development of mould.
Variety of grey tones
Windowsill in RAL 7016 and other grey tones
You can order your window sill in many different colours in our online shop. The most popular colours include classic silver, dark bronze and all conceivable shades of grey.
A window sill in RAL 7016, i.e. true anthracite grey, has an almost timeless look. The colour demonstrates a confident sense of style, does not force itself into the foreground and particularly emphasises different coloured components such as window frames and roller shutters.
The colour is applied to our alu window sills in the form of a durable powder coating. This ensures better weather protection outdoors and at the same time contributes to the longevity of the window sill.
Custom-made exterior window sill with top features
An anthracite exterior window sill can be installed on both plastered and unplastered facades. You can select your size individually online in our configurator: it is best to use the width of the window as a guideline for the cut. The thickness of the wall must also be taken into account for the overhang or depth of the window ledge.
In addition, you can also get premium-quality accessories from our shop.
Side sliding finishes, for example, compensate for the expansion of the exterior window sill when it gets hot.
Noise reduction strips, in turn, reduce the noise caused by rain and hail. Not to mention you can also buy the right screws for installing your window directly from us.
That means you get the exact exterior window sill in anthracite that suits your house – made to measure and at a reasonable price.
