Worker installing windowA window sealant is used to prevent drafts and repair gaps. From acrylic to silicone, these sealants come pre-made for different windows, for example, bath and kitchen windows. Some sealants are also designed to be temporary.

After a glass window installation in your Kansas City, Missouri home, you may realize that there are gaps that let in cold or hot air. Precision Glass notes that you must fix the problem immediately to ensure your comfort at home. This is where window sealants come in handy. The sealants come in different types; you must choose the one that suits the situation.


Silicone is one of the most common caulks. It is transparent and flexible when dry. Top that with a rubbery texture and it becomes perfect for metal or plastic surfaces because they are non-porous. Since silicone is flexible, it will not crack due to changes in temperature. The only downside is that during application, silicone gives off a strong odor.

Latex caulk

Latex is popular because it can be decorated. As such, it is mainly used indoors. Latex suits best to fill wooden window frame cracks. It does not fit for use in cold climates because latex does not adapt to temperature changes.

Butyl rubber sealant

When the holes around windows are big, about 0.63 cm wide or more, butyl rubber caulk is the best material to use. Butyl rubber is so durable it can last for ten years if applied correctly. It can also be painted to blend with your home’s décor. There is also a temporary variation of the same, the butyl cord sealant, which can be used to prevent drafts before fixing the permanent caulk.
