Best window sealants for 2020

It is known that if the windows are not insulated, the heat loss will be high. Therefore, builders recommend using a special sealant that will prevent loss and maintain a stable room temperature. However, there is a problem, there are hundreds of representatives on the market who create a product with different properties, and sometimes it takes a lot of effort to choose the right option. To help save time, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best window sealants for 2020.

What is important to know?

Any sealant is a viscous elastic mass, which is made from a special base. The use of the product is quite simple, a person only needs to apply the mixture to the work surface and wait for it to harden, which can take from a day to 3 days. Over time, a protective layer forms, which not only protects against drafts, but also becomes an obstacle to moisture penetration.

Window sealants are available at hardware stores. They are sold in special cartridges that you can use in a nailer or squeeze the contents yourself. The price and key characteristics of the product depend on the composition. Also, the composition affects the rate of formation of the initial film, which will not allow the mixture to spread over the structure.

Varieties

Manufacturers are constantly improving their products, which is why there are not a couple of items on the store shelves, but dozens and even hundreds. To weed out unnecessary options, it is important to correctly navigate the composition and pay attention to the basis used. Then the person will select the correct model and spend a minimum of time.

Silicone based sealant

The option is popular and is widely trusted by experienced builders. The difference between this product and the rest is the possibility of using it outdoors and indoors. The composition contains high-quality organic compounds that increase strength and durability. In addition, the elasticity is maintained at a high level, and the quality of adhesion to the surface does not leave any questions. And the cost is affordable not only for professionals, but also for ordinary buyers.

They are produced in two types: acidic and neutral. The first option is familiar to many because of an unpleasant pungent odor, which is somewhat reminiscent of vinegar. Despite the rapid weathering, the illusion of its presence persists, especially when a person does not use a respirator. The feature of the product is good adhesion and resistance to high temperatures.

Neutral models are suitable for making joints and seals on plastic surfaces. There is no unpleasant smell. There are also substances that contain elements that resist the formation of fungus and mold. They are often used for residential applications.

Advantages of silicone sealants:

• Durability;
• Good resistance to sunlight;
• Adhesion;
• Easily change shape without compromising tightness.

Disadvantages:

• Not intended for use on wet surfaces;
• It will not work to change the color of the substance;
• Corrosive to concrete or metal (typical only for acidic)

Acrylic

The main feature of this option is easy removal before solidification and high resistance to ultraviolet rays. In terms of performance, the product is practically no different from the previous version. The only thing that is important to know is that the frozen material perfectly absorbs fumes, which makes it darken. If a person does not interfere in this process, then the strip will become completely black, which will negatively affect the appearance. Acrylic sealant is suitable for outdoor use.

The initial curing speed of an acrylic-based product is 15-20 minutes, but full polymerization reaches after 20 days. The main drawback of this element is the impossibility of using it for internal work. Otherwise, this is an excellent option at an affordable price that will serve the user for a long period.

Polyurethane based

A synthetic product capable of providing high-quality sealing for windows or other structures. In addition, this type of product can be used in place of rubber or plastic while maintaining high efficiency. Sealants based on this material are used to seal joints in buildings. Due to its quality characteristics, the product is in great demand in the market.

There are two options - one-component and two-component. The first composition is completely ready for use after purchase. To use the second option, a person will need to mix the substance in certain proportions. If a person needs to repair a large crack, it is preferable to use a two-component product, since the elongation at break reaches over 400%, which is a good indicator.

For household use, one-component polyurethane sealants are suitable. It is one of the best materials for use in various designs, including for windows. Before use, it is recommended to prepare the work surface and remove excess.

Also this type includes a sealant based on polyurethane and silicone. This model has recently appeared on the market. The main difference is high performance and the ability to use it for various purposes. This type of composition can be painted in any color, which is an additional advantage. But there is also a downside - the high cost, which makes it unaffordable for some users.

Thiokol sealants

In this variant, the polymer of the same name or liquid thiokol acts as the main element. It is sold in three versions - one component, two and three. The latter consists of a powder, a base and a vulcanization accelerator (catalyst). By combining these elements, a person will receive a high-quality solution that must be used quickly. The maximum time for work is 2 hours. At the end of the last minutes, the composition will become unusable. Polymerization takes place within 24 hours, but may take less time, it all depends on the type of operation.

The main area of ​​application of such sealants is the insulation of joints in reinforced concrete structures. It is important to understand that the maximum percentage of deformation that a product can handle is 25% and no more than this value. Before use, you should clean the working surface to ensure a snug fit of the substance.

Advantages of thiokol products:

• Indicators of strength and elasticity are higher than that of some representatives;
• Service life - over 20 years;
• Good moisture resistance;
• Does not deteriorate and does not deteriorate from exposure to acids and alkalis;
• Not afraid of exposure to direct sunlight;
• Oil resistant;
• Withstands temperatures exceeding 100 degrees Celsius;
• High-quality connection to the surface;

However, this material also has negative sides:

• When performing operations with thiokol sealant, the presence of PPE is mandatory.
