Warm sill - what is it and is it worth it?

Warm sill is an innovative solution used during window installationwhich increases their thermal insulation and improves the tightness of the frame-to-masonry connection. It is a special profile usually made of extruded polystyrene (XPS) or polyurethane (PUR) foamwhich is mounted under window as an insulating layer. This effectively eliminates thermal bridges, reducing heat loss and limiting the risk of damp walls around the windows.

How the warm sill?

A warm window sill has several key functions:

• Provides better thermal insulation - reduces heat loss, resulting in lower heating bills.
• Seals the joint windows with a wall - eliminates leaks through which cold air could penetrate.
• Facilitates assembly windows - provides a stable and level base, so that the window is precisely embedded.
• Protects against moisture - reduces the risk of condensation and mould growth.

A warm window sill is a particularly good solution for modern energy-efficient construction and passive houses.

What is the eel in window?

What is a carb in the window

A jamb is a structural element that has been present in the construction industry for many years. In the past, it was used in townhouses as a form of additional reinforcement for the frame and to prevent the window from falling out. Its role today, despite technological advances, is still important. In this article, we will discuss what exactly a jamb is, what functions it has and what modern applications can be attributed to it in the context of energy efficiency in buildings.

Definition and history of the carb

A carbuncle, also known as a carbur, is the part of the wall that protrudes at the opening of the window. It is created by extending the bricks a short distance. In the past, in the era of masonry construction, architects designed window openings with a view to optimising heat loss. The sash allowed the window to fit effectively into the wall, resulting in better thermal insulation. Its use in traditional buildings allowed for a reduction in heat loss, which is becoming extremely important in the context of rising energy costs.

Functions of the jamb in construction

Although the carcass appears to be an insignificant structural element, it performs a number of key functions that affect the sustainability and energy efficiency of buildings. Here are some of the most important of these:

1. Thermal insulation: Wool reduces thermal bridges, which translates into reduced heat loss. As a result, buildings are more energy efficient, which in turn reduces operating costs.
2. Sealing and soundproofing: The carburettor allows the window frame to fit precisely into the masonry, improving sealing and reducing external noise, which is particularly important in cities.
3. Aesthetics and functionality: A structural element, the eel can also have a decorative function, giving buildings a distinctive appearance.

Modern applications for the eaves

In modern construction, eaves still play an important role. Thanks to the use of modern building materials such as cellular concrete blocks, the installation process has become simpler. Carbons up to five centimetres thick are installed both on the sides and on top of the window opening, which increases the insulation efficiency.

Warm installation and its importance

Warm installation is the installation method windows, which is gaining in popularity for its insulating properties. In this context, the eaves plays a key role by creating an additional layer of insulation between the window frame and the masonry. This minimises heat loss and significantly reduces the risk of condensation and moisture inside the structure.

What is warm window installation and why is it worth investing in it?

Selection of suitable windows is a key step in the process of building or modernising a house. However, even the best, most energy-efficient windows can fail to perform their function if they are not installed correctly. In recent years, the following have become increasingly popular warm window installation, which responds to the growing need for energy efficiency and thermal comfort in buildings. But what exactly is warm installation and why is it worth investing in it?

What is warm window installation?

Warm installationalso known as sandwich assembly, is an installation technique windowswhich involves the use of additional insulation layers to minimise thermal bridges and improve airtightness windows. In contrast to traditional assembly, where window is installed directly in the borehole window, warm installation includes three key sealing layers:

1. Inner layer - It is responsible for airtightness and prevents the penetration of moisture from inside the building into the window construction. Usually vapour barrier strips or special films are used here.
2. Middle layer - It provides an insulating layer that reduces heat loss and protects against noise. Polyurethane foam or suitable insulating materials are most often used in this layer.
3. Outer layer - It protects against the elements, such as rain, snow or wind. The outer layer must be vapour-permeable to allow moisture to evaporate freely, but at the same time waterproof to prevent water penetration.

This solution provides optimum thermal insulation and protects the building from excessive cooling and moisture.

The differences between standard and warm installation

Traditional window installation involves the use of mounting foam to seal the joint windows with masonry. Although this is a commonly used method, it has the disadvantage of not providing adequate protection against moisture and heat loss. Polyurethane foam, used in standard installation, can lose its insulating properties over time, and moisture that enters the cracks causes it to degrade.

Warm installation while, thanks to the use of additional insulation layers, it eliminates thermal bridges, which significantly improves thermal insulation performance windows. This not only reduces heat loss, but also improves indoor comfort.

What the process looks like warm window installation?

To better understand why warm installation brings so many benefits, it is worth knowing what its step-by-step process looks like:

1. Preparation of the window opening
   Before installation of The window opening must be thoroughly prepared. It is important that the surface is dry, clean and even. The window opening must be suitably shaped to allow for the subsequent installation of the insulation layers.
2. Application of insulation tapes
   In the next step, special vapour-proof and vapour-permeable tapes are used. On the outside of the building, a tape is installed to protect against moisture and weathering, while inside, a tape is used to prevent moisture from penetrating into the structure.
3. Application of the installation foam
   Then window is embedded in the window opening and the spaces between the window frame and the masonry is filled with polyurethane foam, which provides good thermal and acoustic insulation. This foam, despite its insulating properties, is protected by pre-installed tapes to prevent degradation.
4. Sealing and finishing
   After installation windows and foam application, all edges are carefully sealed and the external and internal tapes are carefully adhered to the surface. This ensures a complete seal and protection from the weather.

Advantages of warm window installation

1. Improved thermal insulation
   The biggest advantage warm installation is to significantly reduce thermal bridges, resulting in less heat loss. This keeps the house warmer in winter and cooler in summer, leading to savings on heating and air conditioning costs.
2. Protection against moisture
   Through the use of suitable vapour barrier tapes, warm installation protects the structure windows against the ingress of moisture from inside the building, which is important, especially in winter. Protection against damp is a key element in preventing the formation of mould and mildew.
3. Longer service life windows
   Warm installation extends the life of both windowsas well as the building itself. Adequate protection against moisture prevents material degradation and improves the performance of the windows for many years to come.
4. Improved sound insulation
   Layered technology installation, including additional central insulation, means that warm installation also effectively protects against noise from outside. This is particularly important for houses located along busy roads or in city centres.
5. Energy savings
   Warm installation is an investment that pays off in the form of lower energy bills. Thanks to better thermal insulation windows, the need to heat the building is reduced, resulting in real savings in the long term.

Warm installation and construction standards in the European Union

It is worth noting that in the European Union, more and more countries are introducing stricter standards for the energy efficiency of buildings. Poland and many other countries have regulations which impose specific requirements on new buildings regarding minimum heat loss. Layered assembly, or warm, fits in with these regulations, helping builders to meet the new building standards.

If you are planning to build or upgrade your home, it is worth considering the installation of a windows in accordance with these guidelines. This will avoid the need for additional amendments in the future and at the same time reduce the running costs of the building.

Is warm installation is necessary for all types of windows?

Although warm installation is recommended in the case of energy-efficient windows i passiveThis does not mean that it is not also worth using for traditional window systems. Even with standard windows layered assembly significantly improves the thermal insulation of the building and extends the service life windowsand protect them from the negative effects of moisture and weather conditions.

Like windows affect the acoustics inside the house?

How do windows affect acoustics inside the home?

In today's world, external noise is an integral part of everyday life. Living in a city, close to busy streets, airports or railway lines can have a significant impact on living comfort. One of the key elements that help to reduce external noise is properly selected windows. In this article, we will explain how windows affect acoustics inside the home and what technologies used by GM Plast can help reduce noise.

What is window sound insulation?

Sound insulation is the ability of windows to reduce the passage of noise from outside into the building. It is measured in decibels (dB), where a higher number indicates better noise protection. Standard windows can reduce noise by around 25-30 dB, while specialised soundproof windows offer insulation of up to 40-50 dB.

Factors influencing the acoustic insulation of windows

1. Thickness and number of panes
   • One of the most important factors affecting the acoustics of windows is the thickness of the glass and the number of panes. In double-glazed window systems (insulated glass units - IGUs), the glazing can vary in thickness to help disperse sound waves. At GM Plast, we offer windows with different glazing thickness options to optimise sound insulation.
2. Distance between panes
   • The space between the panes also has a major impact on the windows' ability to dampen noise. A greater distance between the panes allows for better dispersion of sound waves. This is why, at GM Plast, we offer solutions that provide adequate glazing separation to reduce noise transmission as much as possible.
3. Insulating gases
   • Filling the space between the panes with gases such as argon or krypton improves sound insulation. The gas acts as an additional barrier that absorbs sound waves. Our PVC windows are gas-filled, which provides not only better thermal insulation, but also acoustic insulation.
4. Gaskets and window frames
   • Even the best glazing will not work effectively if the windows are not properly sealed. At GM Plast, we use double gaskets that not only protect against noise, but also provide excellent thermal and water tightness. In addition, our PVC, timber and aluminium frames are designed to dampen sound vibrations.

Which windows to choose for better sound insulation?

Choosing the right windows depends on the source of the noise and the level of sound insulation you require. For city dwellers where street noise is prevalent, double-glazed windows with good seals may be sufficient. On the other hand, for those living close to airports or railway tracks, triple-glazed windows with gas filling and special acoustic seals may be a better option.

GM Plast - your partner in the fight against noise

For years, our company has been providing quality windows that help customers enjoy peace and quiet in their homes. Thanks to advanced technologies such as multi-layered glazing, insulating gauze and robust seals, we can offer windows that provide excellent noise protection.
