Leaking and not sealing windows are not anything new. And, unfortunately, the window can leak in, whether it is new or old. It mostly angers in case of a new window. What could be the reason?yť?
The reality is that in most cases of leaks and not sealing, it is not the fault of the window itself. Rather it is what many of us underestimate – installation.What do you focus on when choosing a new window? Are you interested in material, insulating glass, window profile, window sills … ? You forget, however, for the actual installation and do not pay much attention to it. After all, professional comes in and the window will be installed. Well, professionals are not all the same and an installation is not the same as other installation.
ERROR IS NOT IN YOUR WINDOW. BLAME THE CONNECTION JOINT.
If it also happens to you, that during a rain, a wet spot under the still appears, your window was probably incorrectly installed. The problem is in so-called connecting joint.
So what is it? Remember the installation. When they were first put in the hole between your window frame and the wall, the gap appeared. It can have different sizes. It was after sealed by employees of the company that supplied you with windows.
The most commonly used materials to seal the connecting joints are such as polyurethane foam, mineral wool, fiberglass strand or general assembly foam. It fills the connecting joint, dries, cuts and adds to it special glue. And done. Well, it is, really?.
NO, THE FOAM IN NOT ENOUGH
The basic error in installation of windows is that the mounting foam that fills the connecting joint, has only one property – and that is the thermal insulation. This assembly foam must not come into contact with water or direct sunlight. If the water gets to it, foam falls apart and leaking will start occuring. Or it starts to blow through.
It is therefore necessary to carefully protect the connecting joint from the outside. Nowadays, foils which cover the foam around the perimeter of the window, are used for this purpose. But how can you be sure that the workers who will install the window, think about this?
Company from which you purchased the box and that it also comes to install it, must follow a installation standard STN 733,134th. In this installation are clearly defined materials for sealing connecting joints, which will protect you from leaking and blowing. With this kind of installation, you have nothing to fear.
AFTER EVERYTHING, IT STILL LEAKS!
If the water gets to you through other points, it probably isn’t because of the error caused during an installation. Bad insulation of your house or block of flats or a crack in the glass or can be responsible for regular puddles. And it is also possible that your window is simply no longer needed. Keep in mind that plastic windows have a lifetime “only” about 35 years. Thus, if you bought a new window in the first plastic “boom” it might be the time to consider replacing them.
Are you burning with the anger? Did you think that you will not have to change your windows ? Maybe you should reach for the aluminum. Their life is in comparison with plastic windows disproportionately longer and aluminium virtually guarantees that not even one bit of heat will escape your home. But even here, be carefull about one thing: installation STN 733134
