New window insulation standard

In the Selena Standard you will find details on the design and installation of an energy-efficient joint in response to the growing energy requirements for buildings. The European Directive on the Energy Performance of Buildings, which is in force in all countries of the European Union, stipulates that from 2021 all newly constructed buildings must meet the standards of a low-energy house. For buildings constructed by public investors, the regulations are already in force as of January 1, 2019.

Air tightness, weather resistance, water vapor diffusion, temperature factor, thermal and acoustic insulation are the key parameters describing the requirements for sealing and insulating the junctions between frames and jambs, set by both investors and regulations. Learn the technical details on the energy-saving joint

From the moment a window is built into the jamb of a structural wall, the junction between the frame and the jamb, as well as the insulation and sealing systems used, are subject to variable forces from loads caused by a number of external and internal factors, such as atmospheric phenomena, the dead weight of the window structure, object movements, operation, intrusion attempts, impacts, noise, fire, and internal room climate. Learn about the challenges facing contractors as well as partition designers for the coming years.

Check out the details of the complete and necessary technical documentation, as well as the necessary elements of a proper window and balcony door installation project, along with references to legal regulations.

Learn about the 3-layer insulation and sealing model designed for varying external and internal conditions, factors and phenomena affecting windows, and the 3 zones of sealing and insulation of frames with jambs.

Properly designed junction of the jamb with the frame is also important because of the various possibilities of moisture in the partitions also already during the operation of the building, Check the influence of the temperature coefficient on the evaluation of the quality of window installation.

Thermal and moisture conditions, as well as heat and moisture transport in buildings and building elements, are interrelated yet highly variable. See details on the design of a jamb-to-frame seal in which there is controlled, uniformly effective moisture removal from the joint.

Learn about the key regulations for sealing frame-to-frame joints, and check the contractor's responsibility in terms of installation work and technical parameters of the joint.

Read about the necessary elements of the design of sealing joints between frames and jambs as the basis for the smooth execution of a professional and efficient installation, Careful design of structural connections for windows and exterior doors has a major impact on construction work, and thus affects the durability and suitability for use of the installed elements.

See the list of conditions for proceeding with the installation and replacement of windows, the requirements for the connection of windows and balcony doors to the building, as well as the rules for the acceptance of windows and balcony doors before installation.

One of the prerequisites for proper window installation is the transfer of forces from the window to the building structure caused by external influences.

In any case, when designing the width of expansion joints, it is necessary to take into account not only the compensation of forces from loads caused by the phenomenon of linear expansion, but also the appropriate transmission of forces from wind loads, which involves the need for the proper selection of materials and means used to make mechanical connections of the window structure with the structural masonry.

One of the conditions for proper window installation is the transfer from the window to the building structure of the forces caused by external influences. Check the technical details of how to perform insulation and sealing, taking into account the movements of window structures in both directions and adjusting the width of expansion joints to the expected amount of displacement, the properties of the insulation material, and the properties of the materials used to make seals.

The location of windows in the opening of a new building should be specified in the design and technical documentation, depending on the type of construction and thermal-moisture optimization.

To meet the expectations of contractors and investors and bearing in mind the highest quality of materials for insulating and sealing window-frame joints, the Standard for sealing and insulating window-frame joints, developed by Selena, specifies the key parameters of a properly insulated joint. Check the requirements for resistance to rainwater penetration, air permeability and the values of temperature coefficient and linear heat transfer coefficient.

Thermal and acoustic insulation of the joint are the main parameters affecting the comfort of the premises, quickly felt by users. Learn about the factors of insulation measurement that affect the acceptance of installation work.

Check out the technological details for working with products in WINS 3-layer sealing and insulation systems. Only properly executed 3-layer joint sealing provides a sound barrier, protecting the interior of the building from outside noise and eliminates uncontrolled heat loss from the building.

See three proven insulation and sealing systems, based on materials manufactured and supplied by Selena, designed for professional insulation and sealing, the use of which, in accordance with the recommendations and guidelines of the Selena Standard, makes it possible to achieve a result that exceeds the quality standard set based on the requirements of the Minister of Infrastructure Regulation of April 12, 2002 on the technical conditions to be met by buildings and their location, (Journal of Laws 2019, item 1065) and in line with the trends of highly energy-efficient buildings

Meet WINS systems, innovative 3-layer systems for insulating and sealing junctions between the jamb and frame. The systems regulate the flow of water vapor in the joint and inhibit uncontrolled air infiltration, resulting in improved energy and acoustic efficiency of the joint. WINS systems consist of integrated products that, when used as a system, provide the junction of the jamb with the Selena Standard of insulation and sealing.

Check out the details on the three innovative jamb-to-frame insulation and sealing systems WINS Flex, WINS Fast and WINS Fix. They consist of materials designed to insulate and seal within properly designed expansion joints and ensure that the highest results are achieved in terms of thermal transmittance, sound insulation and resistance to rainwater penetration.

WINS Flex is an innovation for new and demanding installations. Highly flexible, highly resistant to extreme weather conditions 3-layer window installation system, requiring no special substrate preparation. It protects even the largest windows from deformation, perfectly transmits all building vibrations and maintains tightness even under heavy loads.

The WINS FAST system-including a different type of mounting foam-was one of the solutions tested early in the system's history. It was phased out in early 2022 and replaced in all functionality by WINS FLEX.

WINS Fix is an innovation for quick window replacement and renovation, including in historic buildings. It is distinguished by the ease with which it seals windows in walls with a corner without disturbing the outer layer of the facade. It provides a weatherproof seal and sound insulation.
