How to properly seal the windows of Thermopan or Wood –

The window seal is a stage neglected by many owners of houses or manufacturers, but has a great importance for energy performance and resistance to a structure. Discover from this guide when it is necessary to grasp the joints of the windows or wooden windows and what is the role of the process. In addition, we present the main advantages and work passages.

When is it mandatory to catch the windows?

Tenuta strips are accessories for thermal insulation. If you are isolating the facade, it is absolutely necessary to grasp the windows, to guarantee the saving of thermal energy and avoid the deterioration of the work due to time, hyglesia and mold. In addition, a building with a pneumatic not of letters loses five times more energy than a correct construction of tires.

The role of the sealing strips

The joints of the windows are a challenge, because the joints must be tight and perform high performance. In addition, an incorrect assembly of the seal strips and the use of inadequate products lead to a low quality of work and there are no expected advantages. Instead, the correct execution provides for three functional levels:

• Joints of insulating joints – contributes to better thermal and acoustic insulation;
• Fit the sealing strips inside – guarantees the holding of the air and has the role of the vapor barrier;
• Mount the holding strips outside – Provides protection against time (rain, snow, wind) and prevents the humidity from entering the house.

Here, below, more details on the roles of the sealing stripes and discover the professional products recommended by macostter.

Assembly inside

Air currents are an unwanted enemy and acting in the area of ​​non -intrusive joints in two directions:

• The cold air from the outside enters the house: it cools the internal surfaces and increases humidity in the rooms, which leads to the formation of condensation and mold;
• The hot air inside leaves the house: heat comfort from the rooms decreases and at the same time ice, mold or microorganisms can be formed due to humidity.

In this case, the Windows sealing stripes have the role of the vapor barrier and prevent the formation of condensation, humidity and mold. We recommend competitions by itself – for the interiors, due to the multiple advantages: it has three separate protection levels, it guarantees high quality and permanent adhesion on several surfaces, included on media minerals and can be plaster. In addition, it is certified for passive houses.

Mount outside

For the correct sealing of the window joints, it is mandatory to install the bands both inside and outside. The latter offers protection against rain, snow and wind. In the basket, it prevents the penetration of water in the construction structures and avoid them, the formation of the mold and the cooling of the surfaces in the house.

The sealing stripes must have a high degree of diffusion of the steam, so that the accumulated humidity and condensation can evaporate in the summer months. Choose the Exo competitor – for the outside for several reasons:

• The ribbon is waterproof and sealing in the wind;
• resists UV exposure up to 3 months after application;
• It is thin and folds excellent in the corner area;
• allows the spread of water particles to keep the joints of the dry windows;

Mount both inside and outside

As can be seen above, the holding strips for internal assembly and those for the outside must have different properties. However, you can opt for products that have both the role of the vapor barrier and the protection against time. We give that they must be mounted in two layers – inside and on the external side of the joints between the windows.

One of the best solutions is Sollto IQ contemplates – for interior and exterior. This is a band of intelligent seal, which refers to the resistance to the variable diffusion between 0.4 and 25 but second of the relative humidity, being 10 times more permeable to vapors compared to conventional products.

Seal the anti -giunto with the expandable ribbon

The expandable stripes increase their volume after installation and protect their home as a rains, snow and wind. In addition, the sponge seal contributes to thermal and sound isolation. Creatd trust Exo has a adhesive part for quick and simple assembly. This can be applied to the profile of the edge or to the windows of the windows or wood, with an anti -cervello role.

The advantages of enveloping windowsThe window seal is a negligible cost in the thermal insulation process of the facade and it is easy to achieve and the advantages are considerable. Only the houses with the garnish tire are efficient and efficient from an energy point of view. Even the smallest objectives between the insulating frame or the wood and the construction walls have a great negative impact.

Discover the most important advantages you can enjoy when you correctly mount the windows for windows or wood both inside and outside.

Savings for thermal energy

Whether you want to build a passive house or improve the energy efficiency of the house, it is mandatory to seize the joints between the different structures of the construction. Therefore, buildings with narrow tires ensure a reduction in heating costs. In addition to the financial benefits, you enjoy a constant and pleasant ambient temperature. The window seal is not advantageous only in winter, but also in the summer months, when the rooms remain fresh longer.

Protection against humidity and mold

Due to the currents of air and humidity that penetrate through the unexpected joints, condensation and mold can be formed. Not only the area of ​​the internal windows, but also the facade of the house, is not interested. As mentioned above, it is not enough to grab the joints on the one hand, but it is mandatory to mount the strips inside and outside.

In this way, the heat is not lost, the appearance of the air currents and the penetration of humidity is avoided and the functional layer is protected (e.g. polyurethane foam to isolate the joints). See other solutions for wet walls.

Avoid damage to the construction structure and finishes

The air ability to retain water is much lower at low temperatures. When the degrees in the thermometer decrease and reach the limit of 100% of the steam absorption level, condensation appears. This phenomenon increases the risk of structures. At the same time, it is very important that the estate range from the outside is permeable to vapors. The diffusion involves the transport and evaporation of the humidity captured within the construction structure.

Eliminate air currents

If there are holes in the insulation layer around the windows, an increase in air circulation is formed. The currents cause great differences in temperature and discomfort. The problem can be easily solved with expandable or, mandatory strips when the thermal insulation of the facade is performed, with internal and external ribbons.

Pleasant and healthy internal climate

When the windows are not narrow, the cold air from outside enters the house. When heating, his relative humidity decreases. The climate at home in winter becomes very dry and the problem cannot be solved with the humidifiers of the camera. In addition, the mold spores that can be easily formed for the construction with non -bed tires are dangerous for health and often cause allergies.

In the case of the correct sealing, these inconveniences are eliminated and the internal climate is ideal. Not only are dry air and mold cause an increase in discomfort.

Correct window seal: work phases

To benefit from the advantages described above, the sealing bands for the windows or wooden windows must be mounted correctly. Here are the main phases to keep in mind:

Window installation

To mount the windows, be sure to use a quality foam, which resists in time without losing its properties. We recommend the Soudal Flexifoam flexible foam. Compared to the usual foams, it does not break and maintains its isolation properties. Flexifoam foam contributes to thermal and sound isolation and remains elastic longer.

Choose the holding strips

Any job begins with the choice of the right materials. On Macostore.ro you will find high quality seal strips, with specific properties for inside, outside or on both sides of the windows. In addition, you must pay attention to the handle and choose the ideal product according to the support surfaces. From this point of view, contest Soldo SL, contest Sollo Exo and contest sold IQ are «versatile»: they adhere to lacquered or plane wood, hard wood panels, hard plastic, aluminum and plaster, brick or masonry cement.

Paste the sealing stripes before mounting the window

The sealing of the windows can be performed before mounting them in the cavity of the wall. Capture the ribbon inside the frame, on the whole perimeter, after which it overlaps some centimeters at the edges. Use a pressing scraper and make sure the maximum grip. The surplus will subsequently be glued to the wall. It is important to form a cycle of at least 4 centimeters (double the width of the joint) in every corner for the appropriate seal.

Paste the sealing strips inside and outside

Usually, enveloping windows are a phase that you have to face when performing external thermal insulation. After filling the joints with insulating material, you can pass to install the seal strips. Here are the most useful tips:

• You can start with the internal assembly or the one outside the seal strips, depending on the project.
• Prepare the support surface: it must be smooth (cut the nails or ends of the cement and the surplus of insulating material), without traces of dust, fat, oil or frost. If necessary, use a spray or a primer for adhesion, as a spimer.
• Choose two or three protective sheets by sealing; These will be detached below, which prevents an improper link and facilitates the assembly process.
• Paste the band along the perimeter, without interruption; It overlaps and paste the ends of two strips of ribbon in the corner area for a correct garnish.
• Press the strips firmly to ensure a greater grip; Press the sealing tape with a scraper.
• For the isolation of the windowsills or the profile of the edge, use the pre – -compressed sealing tape (expandable – type of sponge).
