Keeping your house cozy and energy-efficient requires sealing the seams on your plastic windows. A quality sealant keeps dust, moisture, and drafts out of your home, preserving the longevity and functionality of your windows. Because of their smooth and uniform appearance, white sealants are a popular option among the many that are available.
Knowing the various types of sealants is important when selecting one for plastic windows. For example, acrylic sealants are well-known for being inexpensive and simple to use. They provide a smooth finish and are perfect for indoor applications. They might not be the greatest option, though, in locations that experience severe weathering.
Conversely, polyurethane sealants offer superior flexibility and durability. They can tolerate considerable movement and temperature changes and stick well to most surfaces. Because of this, they can be used both indoors and outdoors, providing your window seams with long-lasting protection.
Another choice is butyl sealants, which are highly regarded for their potent adhesive qualities and water resistance. These sealants provide a dependable barrier against moisture infiltration, making them ideal for outdoor use. However, because of their tacky nature, they can be a little difficult to apply.
Polymer-based sealants offer strong performance and versatility by combining the best aspects of multiple types. They are a good option for both residential and commercial applications because they are simple to apply, have good flexibility, and stick well to a variety of surfaces.
Lastly, polysulfide sealants, sometimes referred to as thiocol sealants, are highly recognized for their longevity and chemical resistance. They can withstand severe weather and are perfect for high-stress environments. They may be excessive for everyday home use, but in industrial settings they are indispensable.
Your unique needs and the environments your plastic windows will be exposed to will determine which white sealant is best for you. You can make an informed choice that guarantees your windows stay well-sealed and protected for many years to come by being aware of the characteristics of each type.

Hermatic for PVC windows
A plastic pasta-like soft mass serves as a sealant for windows made of plastic. Different polymers are used to create a sealant, to which catalytic plasticizers and other ingredients are added.
- After the sealant is applied to the joints between the PVC focus parts, it begins to harden, and then forms an air and moisture-resistant protective layer.
- For plastic windows in most cases, white sealant is used. It effectively protects the insides of the structure from atmospheric exposure and surplus surfaces, plus everything gives them an attractive appearance.
We have provided comprehensive information about all currently available window sealant types below so that you can better understand the attributes and distinguishing features of sealing compositions.
Silicone
Based on organic silicon polymers, this composition is the most widely used and universal. It can be used both inside and outside the house due to its wide range of applications.
Silicone sealant
Characterized by a reasonable price, good adhesive qualities, good plasticity, and ease of use. In total, there are two modifications to the silicone composition: acid sealant and neutral sealant.
When using an acid-based composition, the smell of vinegar is initially detectable but eventually goes away completely in 5–6 hours. A sealant like that doesn’t sit at all, and it keeps its original color and flexibility.
Hermetic sanitary acidic
Crucial! We suggest that you apply a silicone sealant inside the "sanitary" apartment. This sealant is resistant to mold and fungus growth, so even in a humid environment, it will maintain its basic characteristics and whiteness.
Acrylic
Additionally, he is fluid and can be readily removed from any surface with warm water when in an unsteady state.
Because it is resistant to damage from environmental factors like temperature changes, winds, sun exposure, etc., it is mostly used for exterior work and to seal the joints of plastic and polymer-based structures.
Hermetic sanitary acidic
Since the sealant’s porous structure will eventually start to absorb moisture from the space, causing the sealant to darken later, it is hardly ever used for work inside. Many purchase it because of its low price and PVC focus.
Polymer composition on PVC-Osnov
A sealant of this kind is made using MS polymers, also referred to as liquid plastic. He is flexible and possesses good adhesion. Almost a single design is formed with standard plastic after the joints are filled.
The sealant is moisture -resistant
The manufacturer’s only restriction is to avoid using the sealant in areas of the structure that are loaded or where vibrations may cause problems. Since such an impact will result in a sealant.
Polyurethane sealant
Inorganic polyurethane polymers serve as the foundation for the production of this thick and somewhat plastic sealant. This mixture adheres flawlessly to nearly any surface; it also comprises polyvinyl chloride, which is used to make plastic windows.
Butyl sealant
Generated from a polyisobulene copolymer.
- Initial elasticity and elasticity are not lost even with temperature effects from -60 to +110 ° C.
- Not destroyed under the influence of UV radiation, safe for humans and animals.
Pistol for sealant
Theocol sealant
Made from substances containing polysulfide. This particular composition was created specifically to allow the sealant to solidify at any humidity and air temperature. Thus, this sealing mixture can be used in both severe rainfall and severe frost.
In order to provide a clean finish, seal plastic window seams, and stop leaks, drafts, and energy loss, white sealants are necessary. There are numerous sealants available, each with specific advantages and conditions that they are suitable for. These sealants include acrylic, polyurethane, butyl, polymer, and thiocol. Polyurethane sealants offer strong adhesion and flexibility, butyl sealants are long-lasting and waterproof, polymer sealants are versatile and weather-resistant, and thiocol sealants are extremely resistant to chemicals and high temperatures. Acrylic sealants are simple to use and paintable. Making the proper sealant choice will guarantee long-lasting protection and improve your windows’ overall performance.
For plastic windows, selecting the appropriate white sealant is essential to guaranteeing longevity and good sealing. Acrylic sealants are popular for do-it-yourself projects because they are flexible and simple to use. Although they adhere well and can be painted, they might not be the best option for areas that see a lot of movement or moisture.
Polyurethane sealants are very flexible and long-lasting. They are perfect for outdoor applications because they can withstand movement and weathering. For the best results, though, they might be more difficult to apply and need to be handled by professionals.
Butyl sealants are renowned for their long-lasting flexibility and strong adherence. They work especially well for sealing seams that could move a little bit. Despite the fact that they can be a little messy to work with, they are a dependable option in the long run.
Polymer-based sealants offer a well-rounded solution that is user-friendly, flexible, and adheres well. They provide a strong seal without the complications of polyurethane sealants, making them appropriate for both exterior and interior applications.
Thiocol sealants, also known as polysulfide sealants, are ideal for industrial applications or locations with harsh weather because of their exceptional resistance to chemicals and weathering. Although they are incredibly durable, they can be more difficult to apply and frequently require professional installation.
In conclusion, the ideal sealant for your plastic windows will vary depending on your unique requirements and environment. Acrylics are excellent for simple, paintable solutions; polyurethanes are excellent for their flexibility and resistance to weather; butyls offer strong adhesion; polymers are an approachable solution; and thiocols are excellent for harsh conditions. You can select the best sealant for durable and efficient window sealing by taking these factors into consideration.
