The difference between concrete roof and aluminum roof- EuroCS

For a long time, metal roofs have become popular in the construction sector. More and more international-scale buildings and projects use metal roofs because metal roofs overcome the limitations of traditional concrete roofs in terms of quality, cost and efficiency. Moreover, metal roof contributes a great part in reducing waste to the environment. The metal used can be copper, corrugated iron, aluminum but in terms of efficiency, aluminum roof is the most popular option.

1. Limitations of concrete roofs:

- Because of concrete, there is a pool of waterproofing oil on the upper side does not guarantee the ability to heat and insulate, making the house become hot in summer.

- Concrete roof is easily permeable to water, forming drive plates under the ceiling, causing aesthetics.

- When the floor area is large, the elasticity phenomenon should be easily leaked in the structure, the repair and waterproofing is very difficult.

- Very large weight, affecting the foundation structure.

- It is impossible to remove, move and make it difficult to demolish the building.

- When making flat roofs, you must make sure that the foundation is solid. In addition, to prevent heat, it is recommended to make roof tiles above, pour sand on top or use other anti-heat measures.

2. Benefits of aluminum roof:

Aluminum materials beat common roofing materials in many ways:

Watertight, not detected / leaking well against high winds and easily causing dirty objects such as garbage, leaves, dirt, ... to fall to the ground. Aluminum in particular and metal materials are generally resistant to fire, mold, insects and rot.

The warranty period is long, but most companies return their products for 20 to 50 years. Finished paint usually has a 30-year limited warranty.

Weight: Less than 1/5 of the weight of concrete bricks or tiles in the same area, even lighter than other metals. Due to the light weight of the material, you can save technology and build support structures. In fact, if you are building a house or a supplement, you can often shrink or reduce the number of roof supports.

Speed ​​and easy installation of roofing: Aluminum roof has a large length, less joints. A completed contractor can install these things quickly. If your roof is stripped and a storm is taking place, shortening the process in a day or two can bring an important advantage. Obviously, there is also considerable savings in labor if you can easily and shorten the installation time of the roof.

Fireproof: Because aluminum objects are non-flammable, they often have a Class A fire rating (the most fire rated). Just be aware that part of the overall classification of the roof also depends on whether the material beneath the surface can ignite in excessive heat. Most metal roofs are applied on a flammable material such as wood shingles with a lower C rank for this reason.

Thermal conductivity: Aluminum reflects the radiant heat from the sun well, minimizing the heat increase at noon. This means you save the energy you need for air conditioning during the day. Although this material has a low insulating R value, metal roofing sheets can be applied on rigid porous insulation with a very high R value. In addition, many systems use dead space between metal floors and roofs to increase energy efficiency.

Noise: For some people, the sound of rain tapping on the roof is romantic and cozy. For others, it is like living in a drum. Therefore, when used, aluminum roof with its structural system, the house is completely unaffected by the sound of rain. Because, on the one hand, the sound of rain water hitting the aluminum roof is negatively sounded, on the other hand, the mineral cotton layer inside has good soundproofing ability.

3. Disadvantages of aluminum roofs

Although the aluminum roof provides many plus points, there are still a few disadvantages worth mentioning:

Price: The biggest limitation is the initial cost. Aluminum costs the same price as other high-end materials from about $ 150 to $ 600 per square. However, because of the long-term durability of the material, you will save a lot of replacement and maintenance costs. In particular, if you plan to move in a few years, you can remove and move the roof completely without losing too much cost.

Installation: The installer must be careful not to scratch or scratch the roofing sheet during installation, and the panels must be handled with care. Unlike conventional roofing, some aluminum roof systems are installed from the top down, eliminating the need to walk on them. Roofs with exposed screws are particularly vulnerable to improper installation. If screws pierce flat surfaces (not moldings), rainwater can flow down to the roof and penetrate into the screw holes. For this reason, special elastic detergents must be sealed around the screw head. If you install this type of roof, make sure that the manufacturer's instructions are followed correctly.

Expanding & shrinking: Because aluminum expands because of heat when it warms and cools, most new products have a tight-fitting system for movement. On the other hand, screws that secure roof sheets may tend to be loose. Expanding and shrinking on hot days can cause wavy effects.

In Vietnam, aluminum roof is still a new structure, many construction units do not understand the structure and construction techniques, so the use of aluminum roof has not met the expected efficiency. Therefore, it is necessary to invest a large cost for the roof part to find a quality supplier. European Construction System Company Limited (EuroCS) is the first, reputable and quality aluminum roofing unit in Vietnam with Eurozip aluminum roof brand.
