How acoustic insulation of buildings work?

Sound insulation for walls

At the present time, it has become important to take care to isolate rooms and newly constructed buildings, as the insulation helps to preserve the privacy of the population as it prevents from being affected by external noise resulting from the population density in cities in particular, because population density is the reason for the large number of high-rise buildings that contain many apartments, In which there are many people who reside next to each other.

So it is important to preserve the privacy of each house in general through isolation during the construction of the house, and the insulation has many types and benefits, the most important types of which are sound and heat insulation, and the benefits of these two types of insulation are very many, including reducing Noise and reduce electrical consumption, so that good insulation preserves the internal heat of the building, reducing the use of air-conditioning equipment in the summer and heating equipment in the winter.

Sound insulation

Sound insulation is intended to ensure that sound does not travel to and from the place to be isolated, and when placing materials to isolate sound, it is important to understand a lot of engineering terms through which the appropriate type of insulation is determined, such as knowing the speed of sound, sound frequency, sound intensity and other factors that affect the type and quality of insulation. The type of insulating material used in cinemas is not the same as used in homes or companies, and the insulation process is done by placing the materials designated for the insulation process between the concrete while it is under construction, and there are many insulating materials that each type has ideal methods for implementing the perfect insulation.

There are materials for thermal insulation only and there are materials for sound insulation only and there are some materials that can be used as sound and heat insulators together, such: Polystyrene material

Polystyrene foam is a good thermal insulator and therefore it is used as a building insulation material, and it is used in insulating concrete forms and building systems with insulating structural panels.

Revalue prefabricated walls are created by pouring a lightweight concrete filler added to an insulating polystyrene material into a mold and on both sides are gypsum boards that are then treated in a controlled environment, ensuring complete sound and thermal insulation.

Thermal insulation

The importance of thermal insulation

Thermal and acoustic insulation is an important way to  save energy and heat insulation for buildings is to prevent the transfer of heat from outside to inside or vice versa, whether the temperature is high or low.

As for sound insulation, it has two types: preventing the transmission of sound in partitions, walls and ceilings from the outside, or preventing the transmission of vibration and sounds of The machines.

First, thermal insulation:

Thermal insulation is described as the method by which energy is conserved and saved; By reducing the thermal gain, or heat loss, of buildings and equipment.

The heat is transferred in summer from outside the building to the inside, and this trend is reflected in the winter, due to the difference in temperatures between inside and outside, as for the amount of heat transferred depends on several factors, the most important of which is the difference between internal and external temperatures, the thickness of building elements such as walls, ceilings, floors and their area, and the nature The materials that compose them, for example, regular concrete, solid bricks and building stones are considered materials with good thermal conductivity, while wood is a poor conductive material, and the reason for this lies in the air or gases contained in the material trapped inside it, as materials that contain a high percentage of voids Or cavities filled with air or static gases have poor thermal conductivity and vice versa.

Studies indicate that the heat that is transferred through the walls and ceilings in summer days is estimated at 60-70% of the heat to be removed by the air conditioners, while the rest comes from windows and ventilation openings, and this requires the consumption of electrical energy in the summer to cool the building up to 66% of the All electrical energy consumed in the building.

They emphasized that the importance of thermal insulation lies in reducing the consumption of electrical energy used for air conditioning purposes, due to the reduction of heat leakage through walls and ceilings, which also leads to lower costs.

This is what our prefabricated walls have resorted to, and we have made heat-insulating walls and therefore save a rate ranging between 60% to 80% of energy.

In the next article, we will talk about sound insulation and how Revalue used it in its walls

firefighting ready-made walls

New Firefighting ready-made walls

Construction ready-made walls materials can be generally divided into three types including bricks, blocks and panels.

As a new wall material, the lightweight wall panel can be used as an alternative to the traditional combination of solid brick, wall panels in combination with concrete are widely used in interior walls, exterior walls, ceiling panels, floor tiles and partition walls.

Lightweight composite wall panels are prefabricated and machine-packaged in factories, so they are precise and stable. Moreover, it can be sawed, straightened, drilled and nailed, so it can be assembled directly on site and then complete the construction.

Using lightweight wall panels as a building material can reduce labor intensity and reduce construction time.
These materials are characterized by several properties, including water resistance, moisture resistance and resistance to the expansion of freezing water, thus they comply with the Turkish standard specifications and do not contain toxic or harmful substances.

In addition, these materials have high fire resistance performance, so they are also used in all types of buildings and establishments, residential, commercial, industrial and administrative.

Polystyrene is our prefabricated wall material and this material does not have any reaction with fire to emit any dangerous or toxic fumes or gases. A high degree of fire resistance has been observed in the concrete foam and it is a cost-effective fire-retardant structural material that can be used in construction.

The reason behind this amazing property of concrete is due to the presence of the main ingredients being cement and polystyrene. Also, the combination of these materials in the walls produces an inert material that does not interact with fire.

In other words, the concrete material has a lower thermal conductivity value. This low value makes the concrete to conduct heat very slowly act as an ideal shield to protect the adjacent space and the materials themselves from damage caused by fire.
The production of fire-retardant concrete is no different from that of standard concrete.

Reducing cracking in concrete due to high temperatures is achieved by using polyester. This is thus a way to increase concrete’s fire resistance. At temperatures around 160 ° C, these polymers melt and create channels that allow the resulting water vapors to escape.

This process will help reduce pore pressures and reduce the risk of splintering or bursting
According to the Turkish standard specifications, our prefabricated walls take about 114 minutes of fire before collapsing.

In Revalue the agent finds all means of assistance, attention and assistance. Your experience with Revalue will not be local or regional, but rather global.

Characteristics of ready-made concrete walls:

  • Thermal resistance:

The ready-made walls infer the features of their warm implementation mainly from the gauge of protection in depression or inside the reinforcement divider which is usually a metal stud divider.

  • Moisture protection:

Moisture protection in ready-made walls is of great importance as structural parts such as columns and beams are not structurally attached to ready-made walls, sealant used in joints and joints to prevent moisture from entering the building, to maintain homogeneity of ready-made walls and sealants, sealants are used Pigmented.

  • Fire Safety:

Ready-made walls are manufactured with concrete which has a good fireproof material.

  • Soundproofing:

The ready-made wall will give a comparative execution in terms of transmitting sound from outside to inside the building.

  • durability:

The durability parameter for ready-made walls is the same as that of concrete, however the durability depends on the type of connections made with the structural member, any irregularities in the member can be corrected by sandblasting, total wash detection, corrosion, hedging, or various methods.

  • Easy to maintain:

Since walls are made of maintenance-free concrete, the joints, sealants, anchors and attachments used in ready-made walls require regular maintenance.

Types of precast concrete walls

Types of precast concrete walls

Precast concrete walls are a set of solid precast wall panels with typical thicknesses that can be load-bearing or non-load-bearing, in which, articulation, decorative and mix design are available to meet design requirements, the main function of precast walls is to accelerate the construction process In this article, we will discuss the types, properties, and advantages of precast concrete walls.

Types of precast concrete walls:

  • Cladding or Curtain Walls:

Cladding walls or canopies are the most widely used pre-cast walls for building envelopes which are non-load bearing walls intended for use for wind resistance and space encapsulation, this type of pre-cast wall includes partition panels, window divider units, rotating poles and partition covers.

  • load-bearing wall:

Bearing wall units counteract the loads and their exchange from various components and cannot be removed or dismantled without affecting the quality or reliability of the building.

  • Shear walls:

Shear walls are used to give frame parallel to parallel load when attached to stomach activity in floor development, portability of precast shear dividers is generally necessary over direct assemblies.

Types of connections in precast concrete walls:

  • Blocked connections:

Plugged splices are a simplified and fast method of erection process, the final alignment and adjustment can be done later without attaching lever time, the screw should be according to the installation drawings using materials specified by the designer.

  • Welded Joints:

Welded joints are the most common and typical connection in precast concrete installation. These connections are structurally efficient and easily adapt to different field conditions, the connection is usually made by placing a loose plate between two structural steel sheets embedded in the cast in place plate or in a precast concrete panel Casting and welded together.

  • Bolt Connections:

In anchor bolt connections, the strength of the nails in tension or shear depends on the anchor diameter, embedded length, and joint development. Anchor bolts and anchor bolts that protrude from the foundation are the first critical contact with pre-cast members.

Modern technologies save 20-30% of construction costs

The development of the building In the past, the building was constructed using limited materials, such as stones and wood, and it is worth noting that it was designed and implemented by primitive means, but it was effective, and the process of building and construction was done slowly, and lasts for a long time that may sometimes reach For a few centuries, with the passage of time, the means of design, implementation, and materials used in construction developed, so there were huge, modern and complex buildings with a complex design, hundreds of building materials were used in their construction, knowing that their design, planning, and implementation take place in a limited period. And a relatively few, ranging from 2-5 years.

The majority of companies operating in the global building and construction sector have turned to relying on the application of modern technology and technologies in implementing a large number of projects, and employing more new global innovations that contribute effectively to saving time, effort and money in rates ranging between 20 and 30%, while ensuring high quality and services. In the modern building, which guarantees advanced levels of the nature of life for its residents.

The experts focus that saving the cost of construction lies in two important matters, namely, studying the saving in the element of time spent in the implementation of the project, regardless of whether it is a residential building, villa or other, considering that time has a price, and also so that the project enters into the actual investment quickly, and this requires Specific schedules with programmed times.

NOWADAYS Building methods have gone through a fair share of the development of technology and the revolution of discoveries, until there are so-called modern building methods or modern building technology; It completely differed from the traditional methods but kept its quality and durability, so that modern building technology contributed to creating faster and less expensive construction processes than the old ones, and got rid of many of the risks involved, but in return there are other risks that can be overcome with perfect planning and problem solving by engineering methods.

For example Ready-made walls:

Prefabricated panels are a technology used to manufacture floors and walls, but it is not done inside the work site, rather it is prepared in advance, then transported to the site and installed there according to the plan, and this method is highly effective in construction operations that contain repeated walls and floors, as it can be The prefabricated panels contain all building finishes such as insulation, windows and doors.


which is the Better wall system in building?

If you are wondering which option is better in building, light wall systems or traditional bricklaying methods or wood walls, you should read this article!

People have relied on traditional building methods, using stones and bricks for a long time, due to the lack of other alternatives.
