Reseal leaky windowsIf a window seal partially detached from the profile, but otherwise has no damage, it can simply be pressed back into the profile.
If an adhesive seal partially sticks, one could try to re-glue the loose pieces.
In order to find the right glue, however, one would have to know the material exactly - but perhaps you still know exactly which seal that was or recognize it in the hardware store? Then you will be able to recommend the right glue. If the seal is defective, only an exchange helps.
How do you find the right replacement for your profile gasket?
Before the exchange, you must clarify which type of seal is eligible for additional purchase. To do this, remove a few inches of the old seal and take it with you to the purchase. In principle, there are different types of gasket with profile, those for wooden windows without metal rail, for wooden windows with metal rail, for plastic windows and aluminum windows. These seals are also differentiated according to the number of hollow chambers your window has. Without profile come adhesive seals and screw-on seals, possibly in windows with such seals the retrofitting of a seal with profile to consider.
Replacement of the old seal can be obtained from window manufacturers, carpenters or a number of commonly used seals in the hardware store. Are there any difficulties here?
In case of doubt, even a stamp printing of the old seal (cross-section of the seal with stamping ink printed on a paper) will help in the exact search. If the seal used is no longer available, the seal can be re-manufactured by specialized companies. This is more reasonable and cost effective than replacing the entire window, if the substance of the window is still good. Here is an overview of how to replace, renew and maintain window seals.
What has to be considered when installing a new seal with profile
The new gasket must not be stretched when you insert it into the groove, it would later contract and form gaps. Even a compression that would push the seal out of the groove, is
to avoid. If the gasket is difficult to insert, moisten it with a water-detergent solution, it will then slide better into the groove. For many windows, a special reel helps. For plastic windows and aluminum windows, you can use a silicone built-in spray as an installation aid. However, this spray should not come into contact with wood, it could then no longer be painted. Never use greases or oils as installation aids, both of which may chemically react with the gasket material, which could possibly soften the gasket and cause it to stick to the substrate. There are tips for adhesive seals under window seals - renew, replace, replace.
Cleaning gets the full function
In the case of the plastic gaskets, simple cleaning is sufficient, suitable means are strongly rinsing agent diluted with water or neutral side, a soft sponge should be used as a cleaning tool. Never use aggressive cleaners, they can damage the material and shorten the life of the seal. For the care of seals, which are exposed to strong cold (for example in a house unheated in winter) there is a special silicone spray. Also, grease or oils should never come in contact with your plastic gasket, they can cause unwanted chemical reactions with the gasket. A silicone seal can be treated with silicone care sticks and silicone spray. Glycerine and talcum are also used for silicone seals, to the sticking together of seals, or z. B. to prevent freezing. She is insensitive
against household detergents, care should be taken with (nitro) dilutions.
When the windows are to be painted
For all gaskets, check for contact with other substances: Paint a wooden window, remove the gaskets first. When installing the seals, make sure that the paint is really dry, which can take up to 14 days. Otherwise, an adhesive effect may result if the seals are incompatible with the paint. The solvents in the paint can also remove the plasticizer from the sealing material, as a result of which the profile loses its elasticity.
For single glazed windows, which are not to be replaced, the window gasket alone will not yet be able to provide the decisive protection against energy loss. Here, however, you could additionally think of an insulation with window foil.
