What is Precast
Prekast Cephe (GRC) What is Glass Fiber Reinforced Concrete?
In precast facade (GRC) elements, AR (Alkali Resistant)-glass fiber, white cement, silica sand, water and other concrete additives are used. Molds are produced in accordance with the explanations in the architectural project. In the molds formed, curing is done with the spraying technology in accordance with international devices. Instead of assembling the manufactured precast (GRC) elements, they are shipped with appropriate vehicles and then assembled.
Advantages of Precast
NİVA DİZAYN Precast facade (GRC) cladding products can be produced in desired dimensions according to the project details and the applicability of the assembly.
High Wind Resistance
It is produced in accordance with high pressure and wind speeds.
It is light, does not burden the building.
NIVA DIZAYN Precast facade (GRC) coating is very light because it is produced in 1-1.5 cm thickness. 1 cm shell thickness is approximately 20kg/m2. NİVA DİZAYN Precast facade (GRC) cladding Therm products are 4 times lighter than traditional brick wall-plaster systems and 2 times lighter than concrete systems compared to products with equivalent insulation value.
Earthquake Resistant
NİVA DİZAYN Precast facade (GRC) cladding is produced as resistant to earthquake intensity of 9 magnitude. It is also mounted to the building with steel anchor systems suitable for this system. NİVA DİZAYN Precast facade (GRC) cladding system is a product designed to tolerate the displacement problem of loads that may occur during a possible earthquake.
Fireproof
NİVA DİZAYN Precast facade (GRC) cladding products are the most fire resistant non-combustible material in A1 class according to DIN 4102 norm. It does not ignite during exposure to flame and does not emit toxic gases. In addition to the fire resistance of concrete, it insulates fire and creates a fire barrier thanks to the rock wool used in NİVA DİZAYN (GRC) products.
Provides Sound Insulation
When the advantages of precast compared to other exterior cladding materials are compared; It can be produced in unlimited surfaces and textures, it is light, it is earthquake resistant, it saves space indoors, it has high thermal insulation value, it is strong and durable, it is a fireproof and waterproof material, it has high sound values. It stands out easily with its features such as insulation, freedom in production dimensions, ease of assembly and high wind resistance.
Can Be Produced in Unlimited Surface Shapes and Textures
The features of NİVA DİZAYN Precast facade (GRC) coating are not limited to durability. NİVA DİZAYN Precast facade (GRC) cladding can be produced in any pattern, texture and color. It can be colored with pastel tones to give the appearance of natural stone or wood. Facade elements that store sunlight thanks to reflective materials that can be mixed into the compound of NIVA DIZAYN Precast Facade (GRC) cladding, reflect this light at night, giving your building a unique, illuminated appearance. Thanks to this special surface, your building has a radiant appearance in daylight...
Saves Space in the Interior
NIVA DIZAYN Precast facade (GRC) cladding panel products do not narrow the indoor usage areas, as they are mounted on the outside of the reinforced concrete with the logic of curtain wall. It Saves Space In The Interior.
Robust and Durable
HMK or Nippon branded high alkali resistant glass fiber, which has proven its quality against other fiber brands and types, is used in the composition of NİVA DİZAYN Precast facade (GRC) coating products. Poor quality glass fiber reacts with the alkali elements in the concrete and melts over time, the elements lose their properties and cause serious safety and quality problems. NİVA DİZAYN does not compromise on quality in procurement and use of raw materials.
Waterproof
NİVA DİZAYN Precast facade (GRC) coating is waterproof thanks to the special polymer chemicals it contains. GRC concretes have a water/cement ratio of 0,32 – 0,36% due to their production technology. This feature ensures that the porosity of the concrete is very low and reduces the water permeability. In addition, in natural or self-colored PREKAST (GRC) concrete applications where no paint will be applied, it can be made water-repellent and resistant to pollution by optionally adding special chemicals. Polyurethane roving and polyurethane mastic are applied to the joint gaps between the applied system. In this way, air-water flow is prevented and flexibility is provided to the movements of the facade elements.
Can Be Produced In Desired Sizes
1 cm thickness of NİVA DİZAYN Precast facade (GRC) cladding panels provides over 30dB sound insulation. These values are increased with rock wool used in accordance with the realized specification and different production techniques.
Freeze and Thaw Resistance
NİVA DİZAYN Precast facade (GRC) cladding, GRC precast elements are successfully applied even in cold climates where the freeze-thaw cycle is intense. GRC facade panels, which were applied 30 years ago in Toronto, Canada, where the freeze-thaw cycle is an average of -65 degrees annually, still preserves its original state today.
Ease of Installation
NİVA DİZAYN Precast facade (GRC) cladding system, which expresses the most obvious advantages of precast, is that it can be applied faster and easier than the assembly of other facade systems.r..
What are Precast Facade (GRC) Assembly Details?
A joint gap of 8-10 mm (±2 mm) is left at the joints of the precast (GRC) elements, these joints are then filled with polyurethane-based mastic. The design of the precast facade (GRC) elements, the production in accordance with the specification, and the assembly are completed according to the details of the work.
