The installation of ebb tides is an important stage in the installation of window structures and it is not worth transferring it for later, since in addition to the aesthetic function, external window sills also play a significant protective role. In other words, it is important not only that your windows will look harmonious and complete, but also the safety of the facade from the effects of various weather conditions. Of course, their main function is to prevent moisture from accumulating on the outside of the window block, penetrating into the cracks, thereby causing harm. And in order for the external window sill to be as reliable and suitable as possible, it is worth paying attention not only to the installation process, but also to the choice itself. This is what we decided to talk to you about today.
1. Types of window sills
Before proceeding with the intricacies of installing ebbs for plastic windows, it is worthwhile to understand a little about what types are generally present on the market. Along the way, we will also receive answers to questions such as what advantages or disadvantages they have, as well as assess their practicality in certain conditions. Today, ebbs are made of various materials, in accordance with the design, taking into account the windows and the facade, which is logical in itself. However, not all of them are equally effective in different conditions, and they have different levels of popularity among users.
The first and fairly common material in the production of ebb windows for plastic windows is tin. However, we are not talking here about galvanized tin sills, as they have long ceased to attract the attention of buyers. For that, by the way, there are several very good reasons. Once popular, they were made from a thin steel sheet coated with zinc to prevent corrosion. They were considered quite tough and did a good job at damping vibrations from raindrops falling on the low tide. However, there were some drawbacks here, which turned out to be much more critical than the advantages. They turned out to be absolutely unstable to an acidic environment, and therefore did not take root on the market.
Installed in large cities, where there are acids in the sediments, even in the smallest amounts and in dissolved form, such ebb tides quickly fell into disrepair. As a result of this effect, the zinc peeled off, exposing the ebb, making its appearance unpresentable, and the sheet itself prone to deformation and corrosion. Fortunately, they were replaced by polymer (also known as polyester) tides, which have a much higher security due to the presence of a polymer coating. Although, in fact, under it are all the same galvanized ebb tides. And yet they appear to be much more durable and acid-resistant than their predecessors.
Another advantage of the latter is also a wide variety of palette when choosing. That is, you can find or order the tides of the color you need, so as not to violate the color scheme of the window block or facade. They have, however, a small minus, which is that in handling them you need to be as careful as possible, since leaving a scratch on them is a simple matter. Basically, this type of ebb is considered to be one of the most common, since with correct and high-quality installation, they can last at least a couple of decades.
Plastic ebbs can be called less popular in the domestic market, since they suffer from a similar mechanical problem, like the previous ones, only several times stronger. Birds, as well as falling icicles, will not find it difficult to scratch them, and the chances of damaging the plastic by negligence are much higher. On the other hand, they still have advantages. It would seem, despite such fragility, they are very durable and can withstand various atmospheric influences well. True, in a continental climate, external window sills of this type may not withstand a sharp temperature drop.
From the point of view of popularity, aluminum castings are much more in demand than plastic ones. This is even though they are relatively expensive. Although, probably, everything here depends on the quality, which fully and completely justifies such a cost. The point is that aluminum seems to be much more durable than the materials of the two previous options. It does not deform, does not bend, does not fade and is not subject to corrosion, which allows such an ebb to last for a very long time, while maintaining its factory external features and useful qualities. True, the choice of colors is getting tighter and more limited here, basically, you will come across white, gray, beige and brown options.
There are also stone ebb tides on the market, but they are more of a luxury than a necessity. They are made mainly of sandstone and granite and are extremely durable and weather resistant. And yet, many are stopped from installing such ebbs by the cost, which is beyond the reasonableness of such a purchase. Yes, it is beautiful, but, for example, in a multi-storey building there will be no use for such an ebb and flow. For these reasons, they are not particularly popular with most consumers. Nevertheless, if you are determined to give the facade of your home an exclusive look, then you may like them.
By and large, your choice will be determined by exactly what material the ebb tide you preferred to purchase, as well as the presence of a suitable color for you. It is clear that when installing, say, a brown window block that imitates a tree, it would be silly to put a white tint. However, do not forget that the palette of colors at low tides is not the same and can vary greatly depending on the species. This, of course, is trite, but if you want an exclusively red aluminum sheen, you will not get what you want. True, after listing the main features of each of the types, you will surely be ready for what awaits you in the market and decide on ideas in advance.
3. Installation of ebb
Before moving on to the tips and main aspects of this important event, it is important to understand that for those who have absolutely no construction skills, it is best to seek professional help. This will allow you to avoid some gross mistakes, which can subsequently lead to various kinds of problems. However, despite this, it can be much easier to install an ebb tide than it seems at first glance. The main thing here is to strictly follow the technology, which is the same for any ebb, and then the risk of problems will be minimal.
At the initial stage of installation, you will need to carry out a simple, but rather important manipulation, namely, to properly cut the ebb so that it fits into the required space. The main thing, by the way, in this case is not to forget that it will be necessary to leave enough space at the edges, since they must bend onto the side slopes. It will be enough to leave at least 1 cm from each edge, since it is better to do it this way if you want to avoid wetting the slopes and protect them more reliably.
True, this is still half the trouble, since it is important to remember about the width of the low tide. In no case do not install the ebb flush with the wall, otherwise the water will drain exactly onto it, and this is exactly what you are trying to avoid by installing the ebb. True, too long a visor is also not worth doing, since, despite a high-quality and reliable fastening, in a strong wind, a far protruding ebb can bend, if not tear it off at all. The latter, however, is more relevant for residents of resort towns, where a crazy wind often blows. In other words, when adjusting the dimensions, it will not be superfluous to take into account the weather conditions familiar to your places.
Of course, before proceeding with the direct installation of the ebb tide, you should thoroughly prepare the lower part of the slope, otherwise experts do not recommend starting its fastening right away. Fortunately, nothing particularly difficult awaits you. It will be enough to clean the lower end of the window opening from possible dirt and open it with a primer. After that, all that remains is to glue a special vapor-proof tape that protects this area from liquid ingress, and even in a gaseous state, as you might guess from its name. It is also able to remove excess moisture from the wall. Glue the tape with one edge to the frame, and the other to the lower ebb.
The last step in installing window sills is fastening. And first you have to take care of the ebb cushion if you want to approach this issue as well as possible. Previously, it was most often made of cement, but today everything is done much more simply – frost-resistant polyurethane foam is blown out under the ebb. And if you do not want the precisely calibrated angle of inclination along with the smooth surface of the ebb itself to be distorted, then it would be best to use foam with a minimum expansion force.
From the side of the window, the ebb is fixed to the frame expander with the help of “fleas”, as small screws for metal are often called. You can also pre-walk the sealant at the place of its connection with the window frame to prevent moisture from entering the lower part of the window. When installing an ebb for plastic windows, it would be most logical to use a special groove, which is provided by the manufacturer for this very purpose. Some experts also recommend the use of a support profile to reinforce the waterproofing when it is necessary to install a sill below the frame level.
The final touches in the installation of the ebb will be the sealing of the joints at the points of its connection with the walls. This can be done either with a sealant or with a simple cement mortar.
So, as you have seen, in fact, the process of installing an ebb for plastic windows is not something incomprehensible and overwhelming. All this can be done without having highly specialized skills, and any of the components for work is available in every hardware store. Of course, you can mess up everywhere, so don’t be afraid to seek help from specialists. You may want to watch the work once and finish the next window with your own efforts.
