Ultimate Guide for EPS Sandwich Panel

Introduction

The origin of building and construction dates back to the age where people pitched tents for habitation. Then people began to make buildings of bricks and mortars and buildings made of woods. With modern day technology, the uses of prefab houses that are constructed in the factory arise.

The prefab houses were created to solve many problems. Some of the problems solved with the use of prefab houses were that of excessive time and money people have to sacrifice just to get a building standing. In this light, the study guide is a product of research into one of the best prefab house materials that you can use for your building. This is the EPS Sandwich Panel. This guide contains the basic things you should know about EPS Sandwich Panel from a consumer&#;s perspective. You have something integral to learn about EPS Sandwich Panel.

Chapter One: What is EPS Sandwich Panel?

Figure 1: EPS Sandwich Panel

Like all sandwich panels, EPS Sandwich Panel is made up of more than one materials or layers. Its material properties may include any of polyurethane foam, fiberglass, or mineral wool, and expanded polystyrene (EPS). While many of the former materials may either be combined or unused in the making, expanded polystyrene remains the predominant material used in the production of EPS sandwich panel. This is undoubtedly the reason why EPS Sandwich Panel goes by its name.

What is EPS?

Figure 2: EPS Sandwich Panel

Consisting of a tiny hollow spherical ball, expanded polystyrene (EPS) is a cellular plastic material that is light inweight. EPS Sandwich Panel does not react when mixed with other components. For this reason, EPS Sandwich Panel does not decay easily. Also, it does not serve as organic food or nutritional provision for biotic detriments. In addition to its strength, lightness in weight, ability to carry heavy loads, and longevity.EPS Sandwich Panel stands as resistance to fire for up to 65%. This makes it a B1 noncombustible material second to rockwool sandwich panel only. Also, just like all sandwich panels, EPS sandwich panels scores high point in terms of thermal insulation and protection from rigid climactic conditions.

EPS sandwich comes in galvalume or PPGI steel that ranges in the value of 0.4-0.8mm. EPS sandwich panel has a density that measures within the range of 12-20 kg/m3. Its thickness ranges between 40-200mm. Its thickness, density, and minimal thermal conductivity make it a B1 fire retardant insulation panel that has is globally recognized.  EPS sandwich panel width is measured at either mm or mm but its length is absolutely immeasurable. Its length is left to be determined by users. However, for transportation sake, it will be divided into a maximum 11.85m so that it can contain the 40HQ shipping container. At Sunnyda EPS sandwich panel manufacturing company, a minimum of m2 of EPS sandwich panel is produced daily. So you should know no matter how large your order is, it can always be met. EPS sandwich panel gives longevity to color. Also, EPS Sandwich Panel comes in either white, blue or red for any order quantity. When order quantity more than m2, can custom made any RAL color.

Figure 3: EPS Sandwich Panel

Thermally Insulated Roof: A house is incomplete if the roof of the house doesn&#;t guarantee occupants protection from natural occurrences like rain or sun. EPS sandwich panel is not susceptible to leaking and as such is perfect for roofing of houses made with any kind of material.

• The floor of a House: EPS sandwich panel is inert. It does not react to decay or rot if contact with other material properties. It&#;s thermal insulation also helps balance the temperature of your floor.
• Wall of House: EPS sandwich panel is not only pleasing to the sense of beauty but it is also color-friendly. However, you can&#;t paint your EPS sandwich panel with any color of your own. You can only choose the RAL color as provided by your manufacturer.
• The facade of the Building: You can use EPS sandwich panel in all the exterior part of your building.
• Storage and Distribution of Fragile Materials: One of the distinguishing features of EPS sandwich panel is this reason, EPS Sandwich Panel can be used as a storage facility.
• Offices: EPS can be constructed in the factory and erected on your site into an official structure of up to three-story building.
• Mobile Restrooms for Parties and Occasions: You can erect your EPS sandwich panel for just two hours and set up your toilet facility to serve you for a short period of time.
• Private House: You can useEPS Sandwich Panel for your private house for time-saving construction and cost-efficiency.

Having seen some of the uses and application of EPS sandwich panel, it is time we saw more of its characteristics.

Chapter Three: EPS Sandwich Panel Fire Behaviour

Generally speaking, users are usually concerned about various sandwich panels&#; reactions to fire.  Some users still are scared of the use of sandwich panels in general because they think it is combustible. However, it is not. In this chapter of the guide, you will be exposed to EPS sandwich panel reactions to fire.

What determines the level of resistance to fire that a sandwich panel holds are factors which include its coating, its thickness, its foam, and its density.

EPS sandwich panel maintains a satisfactory resistance to fire when installed correctly. It does not cause any inappropriate fire hazards. However, according to the recommendations and building codes of recognized International agencies like International Code Council (ICC) and Canadian Materials Construction Centre (CMCC), there should be a thermal barrier applied to expanded polystyrene material.

In research conducted by the British Insurers and the Building Research Establishment, the study shows that it is impossible that sandwich panels start a fire on their own. When they burn, it is usually caused through direct contact with areas that have high risks of hazards, areas like, oven and kitchen. Fire usually spreads because it was not duly contained in these areas.

At a burning point, EPS sandwich panel reacts like different hydrocarbons like paper, woods, and related products. EPS sandwich panel softens when exposed to 212oF or 100oC. The burning status of EPS sandwich panel depends on the level of temperature at that time, the duration to which EPS sandwich panel is exposed to that temperature, and the availability of oxygen or other fire extinguishers around that area.

EPS sandwich panel ignition is possible when it is exposed to an open flame. If the flame temperature is higher than 680o F or 360o C, EPS sandwich panel will ignite. Once there is exposure of burning at above this temperature, the whole of EPS sandwich panel will be consumed. There is a dense smoke that is produced at the level of ignition.  This dense smoke contains monostyrene, hydrogen bromide, carbon monoxide, and other aromatic compounds. The emissions of these chemical reactions change depending on fire temperature. It is significant for you to know that this emission is not as harmful as many natural properties. As a matter of fact, it ranks low in terms of harms compared to other natural materials like wood.

Conclusively, EPS sandwich panel is a B1 fire resistant material. This means its combustibility is low. With it, you only have to be careful of rigid fire temperatures having direct contact on it.

Adaptation to Different Weight: This is a very distinguishing benefit that can not only save you transportation cost but can also assure that sudden collapse of EPS sandwich panel building is impossible. EPS Sandwich Panel is light in weight when it comes to carrying and lifting. However, it has the capacity to carry heavy loads.

• Inert Capacity: When a material is inert, it simply means that material does not give reaction when contacted with other materials. For example, water can make steel rust. However, in the case of expanded polystyrene sandwich panel, water will readily have no reaction. With this capacity, EPS sandwich panel is inert. Also, EPS Sandwich Panel features resistance to acid and alkali.
• The barrier to Environmental Impurities: Environmental barriers in a building are an excessive natural phenomenon that does not make living conducive when exposed to them. This includes rain, vapor, sun, heat, wind, and dust. EPS sandwich panel protect occupants from exposure to these barriers.
• Effective Thermal Insulation: With a sound and effective thermal insulation, EPS sandwich panel guarantees users a serene environment.
• Soundproof Capacity: EPS is instrumental to arrive at an atmosphere that is free from noise. If you are into acoustics, you know what this means. You don&#;t get to cause a nuisance in your neighborhood for doing your duty since your sound is well contained in your building alone. Also, you don&#;t get to experience situations of noise from outside disrupting your internal sounds.
• Cost-efficiency: A sum total of all your expenses from purchasing, to delivery, constructing, and maintaining are cheap compared to the total expenses it will cost you to construct other building.
• Time-Efficiency: There is something that makes EPS sandwich panel outstanding; it is its time-efficiency. It takes an approximate time of seven days to get your EPS sandwich panel ready. It takes two-three weeks to erect it on your site if you are using it as a building. There is no other building that promises this kind of efficiency in the use of time. For your time efficiency benefit, choose EPS sandwich panel.
• It is Reusable: You can use your EPS sandwich panel for other things after it must have been used for its primary uses and application. You can even sell EPS Sandwich Panel for those who specialize in breaking down materials and reusing its components for manufacturing other products.
• Longevity: EPS sandwich lifespan ranges from 5-20 years.
• EPS sandwich panel are Anti-fingerprint when you choose anti-finger surface steel.
• EPS sandwich panel has good rust resistant, as surface steel is treated.
• Cheap Installation Cost: With the use of EPS sandwich panel, your installation cost will come cheap. This is because you don&#;t need any special tools before you apply your EPS sandwich panel to the designated area. Only screws are needed. This will save you money of buying traditional building materials like cement and the likes.

Having seen some of the benefits of EPS sandwich panel, there are some factors you need to note before ordering for yours.
