"PERFORMANCE WALLS" in Zero Energy Buildings
Our recent journey of knowledge, that has gained a dizzying speed among the phases of our world, has risen with the industrial revolution. Transferences and experiences that will be left to future generations with our environmental awareness can be provided with the proper materials and applications as a result of accurate calculations. With the awareness of indoor comfort quality and environmental impacts, accepting that each individual has a responsibility to the society in this, awareness-raising activities has gained great importance.
Indoor comfort quality means the proper materials and applications of the walls, floors and suspended ceiling forming the interior. When we say performance walls, it put forwards some features expected from the wall. Because the wall is not only a partition element, but also a concept that brings earthquake resistance, fire safety, heat and sound insulation.
Comfort is a concept demanded in the interior. Because the end user, who has not experienced what comfort is before, cannot know what both safety and comfort provided are. At this point, Performance Walls come forward for interior walls that will provide the right comfort within the framework of regulations and standards. The dry wall systems used in performance walls can show much higher performance than traditional methods. Gypsum-based materials used in dry wall systems have a very old place in our civilization history.
Even though it is not known exactly when the date of processing and using of gypsum began, it was seen that gypsum was used as a plaster material in the walls, ceilings and floor coverings in Çatalhöyük, which is considered as the cradle of civilizations. It is known that gypsum was widely used as a construction material later in Sumerian, Assyrian, Egyptian, Greek, Roman and Seljuk civilizations. It is understood that gypsum was used in every building tradition throughout history. The London fire in 1666 can be considered as a milestone in terms of the adoption of the use of gypsum by large masses. The use of gypsum, which was observed to protect wooden structures during this disaster, was made mandatory by law in Paris in 1667.
Significant studies have been carried out to develop and research the use of gypsum, which is one of the most important traditional material used in our buildings from past to present. Nowadays, where building materials are expensive, economic, high quality, long-lasting and durable products are brought to the building sector by improving the use of plaster in buildings.
Performance Walls – Earthquake:
It has been observed that the load on the building during the earthquake has a direct proportion to the weight of the building. Performance Walls, which are created with plasterboard systems, provide an advantageous application with the lightness in terms of the load it brings to the building, especially in earthquake zones. Since plasterboard systems are light and flexible, they allow the building to be exposed to lower forces during an earthquake and minimizing the damage that may occur by lightening the structure. Besides, the use of lightweight materials instead of heavy building materials will facilitate search and rescue efforts, and castaways trapped under lightweight systems will have a higher chance to survive. Performance Walls, which are adaptable to the movements of the building during an earthquake, are preferred in terms of safety of life and property.
Performance Walls – Thermal Insulation:
Energy efficiency targets have a very significant place in the basis of national strategic goals such as effectiveness of the fight against climate change, ensuring security of supply in energy, sustainability of energy costs and minimizing the risks arising from external dependence. Although plaster and plasterboard are not thermal insulation materials, high Performance Walls working together with thermal insulation materials and bearing profiles are indispensable elements of system solutions. By Performance Walls system solutions, the energy need of the building by providing high thermal insulation performance both throughout the building and between different spaces within the building are reduced. The thermal resistance of the interior walls is very important in providing different comfort conditions in different environments within the same building. Besides, by means of Performance Wall to be formed with profiled plasterboard systems from the inside and / or outside of the exterior walls, it helps to prevent undesirable heat losses in the building, help to save energy used for heating in winter and cooling in summer and provide sustainable comfort conditions.
Performance Walls – Fire Safety:
The potential flammable amount in the building is the flammable load. It includes both the structural elements and the constant or live loads inside the building. Deaths in a fire are mostly the result of poisoning by inhaling toxic gases. The smoke generation potential of materials is known as smoke load. Gypsum is a non-flammable material and has been recognized for centuries of fire protection. The fire resistance of Performance Walls created with plasterboard systems is effective in passive protection of the building and people against fire. Performance Walls tested in the laboratory provide resistance against fire from EI30 to EI120. How many minutes of protection is needed in which area is specified in the Fire Regulation. How long the Performance Walls should not conduct both high heat and smoke during the the fire are determined according to the design. Choosing the proper strength of Performance Wall is very important for security.
Performance Walls – Sound Insulation:
Noise pollution has been increasing continuously since the 1960s and studies are carried out specifically on this subject. In places where noise control is crucial, indoor solutions have an important and critical value in terms of sound insulation. On-site detail solutions to be created in architectural design will positively contribute to the perception and quality of the space. Preventing the transmission of sound from one place to another is realized by the solution of sound insulation as a system. The volume and building acoustics regulations play a significant role in meeting the comfort conditions. Building acoustics deals with the issues related to the transmission of sound or noise from the boundaries of enclosed volumes to inside or outside, and within this scope, it includes the sizing of the wall surfaces and the selection of appropriate materials. Performance Walls, which are created with plasterboard systems, provide both sound insulation and acoustic comfort with different detail solutions in the place. In this context, the regulation created for this purpose in our country plays an important role in determining the systems we will apply directly. The details that is created to achieve the limit values given in the regulation will increase the indoor comfort. Performance walls have wide system and technical performance standards to help you find the ideal solution while designing a place.
Indoors where we spend most of our time should be healthy and safe environments. This necessity comes forth during the design phase. Performance walls are one of the most significant building elements that come forward both in the design and application of these places. Choosing the proper system will bring the accurate solutions in the long run. Performance walls include plentiful solutions in many field from seismic design to thermal insulation, from fire safety to sound insulation.
