Reducing the heat of the zinc roof requires its own technique in its application.This type of zinc roof is usually used as a roof cover on buildings such as warehouses or factories.Although quite often used and quite popular among the public, it's just unfortunately has the effect that can make the room feel hot in its application to the building.

Because of the heat factor, so the roof of the zinc feels less comfortable to be applied to a roof of the house. If you decide to remain an option for use in your dwelling, you should add a heat reducer as an Insulator in the application. This insulator will provide an effect that can make the zinc roof become relatively comfortable to use on the roof of a dwelling.
During the day the heat temperature that occurs in the room, caused by the process of radiation heat transfer from the roof of the roof to the bottom of the house ceiling. The temperature during the day due to the heat of the rays can reach about 70ºC. The process of displacement as a result of radiation heat is a phenomenon or something quite unique to be observed. Under these circumstances, the process of rising temperatures will go hand in hand with the increase in heat radiation. For example, a roof located at 70ºC can emit more than 10 times the heat radiation to the ceiling beneath it. As a solution for handling rising room temperature is by reducing the existing heat radiation in buildings.

The best method as a way of reducing the heat of the zinc roof is by blocking most of the heat through the layers of material that will become the insulator. This coating material will be placed under the roof, adjusted to the type of roof selected.In the application of this insulator, the bottom of the zinc roof will be coated with:
1. Using Aluminum Foil
Aluminum foil is an ideal coating as a function of sun radiation retention with the ability to up to 97% of the total radiation coming into the roof, because of its non-absorbing heat, but reflects heat. Aluminum foil is a popular choice to anticipate hot zinc roof.Advantages of selection of aluminum foil coatings: - It is a good insulator or heat sink.
- This aluminum foil material is made of strong material, elastic, water resistant and freon.
- Besides other advantages is the nature of the material is relatively safe as a roof coating.
- Environmentally friendly.
- Protect buildings from leaks and tampias due to rain.
- Serves also as a protective ceiling of the damage due to the fat that can be caused by the heat temperature of the sun.
- Make the ceiling clean and free of dust or dirt coming in.
- Practical because the installation is quite easy.
- Has a sturdy aluminum structure consisting of:
- Foil contained at the top. Its function as an antidote to solar radiation up to 97% of light coming into the roof.
- Airbag (bubble) or air cavity lane. Its function is as a radiation-retaining lane that goes into the ceiling located under the aluminum. In the process, this air bag is a roof ventilation that will help cool the incoming heat, as well as function to remove the excess heat back to the outside of the building.
- The anti-tear layer on the bottom. This aluminum foil coating is able to withstand loads up to 100 kg and as an anti-tear material.
Stages of installation of aluminum foil as roof coating, first prepare the materials used, for example:
- Wire mesh
- Paper aluminum foil
- Glass wool
If so, the next process is the installation stage:
- Install the wire mesh first on the roof truss.
- After the wire mesh is installed, the next step is to install a layer of aluminum paper just above the wire mesh with the position of the shiny part at the bottom position.
- Once the aluminum foil aluminum is seated perfectly, the next stage is covered with a glass wool just above it.
- If the completion of the stages, then the roof coverings can be installed.

2. Using Styrofoam (EPS-Expanded Polystyrene System)
Styrofoam panel is a kind of panel sheet in the form of an insulator made of plastic material that has special properties with structures composed of granules containing air with low density. Inside there are spaces between the grains that can not deliver heat.This is what causes Styrofoam to be a good Thermal Isolation and as one solution how to reduce the heat of the zinc roof. The use of this type of material has actually been introduced since a long time, but began to become popular again in the last ten years as an alternative material that is effective enough to reduce heat in buildings.
With the advancement of modern technology, the function of this panel that previously only as a food wrapper, now can be made to condition the temperature in the room. The use of Styrofoam has a characteristic as a protective panels that function to be able to inhibit the sun heat from the outside into the room he protected. Panel sheets commonly used for walls, on the market generally has a size of 120cm x 240 cm with a thickness that varies from 2 cm-15 cm. For roof panels of different sizes owned can be tailored to their needs.
Resistance capability or insolation of heat from Styrofoam has been tested by irradiation testing with spotlights and also testing it by confronting the panel toward other heat sources in place of sunlight at a certain distance. On the opposite side, air temperature measurements are made, and then comparisons with air temperature near heat sources of equal distance without Styrofoam. The purpose of this test is to get an idea of how effective Styrofoam can inhibit the effects of heat generated. This test test is done up to several times by using Styrofoam panel with different size and thickness. This heat test resistance can be proof that Styrofoam is a material that can be recommended as a solution how to reduce the heat of the zinc roof.
You can also do this type of trial yourself in your place by Take Styrofoam in glassy form, then fill with hot water with a temperature of 100ºC. Directly you will be able to feel that the water will only feel warm in your hand, like at 25ºC only. With a small trial you can already see proof that Styrofoam is a medium that can inhibit heat. It is ideal to apply on the roof as a way to reduce the heat of the zinc roof.

Styrofoam panel usage function can be used as coating tool on:
- Building walls lining various materials (walls, bricks, concrete, etc.)
- Floors lining various materials (marble, ceramic, parquet, etc.)
- Roof of buildings with various materials (zinc, asbestos, tiles etc.)
- Indoor decor
Excess Styrofoam usage:
- In the construction system, styrofoam is a sealed panel where the air permeability is very small. The materials they have can stabilize the room temperature conditions, where the positive impact is to reduce the temperature of heat or cold that enter into the room, because it can be retained by this panel. Another positive effect is to reduce the cost burden for heating or to cool the room temperature.
- In terms of installation elements, installation of this panel is very easy to apply. The required installation cost is not large, because it is quite economical. Each sheet of manufactured panel is fabricated with the join system. Therefore for the installation process will be very simple, and does not take a long time.
- Each sheet of the sheet has a thickness of 2-15 cm, so it is very light in terms of weight and for the process of removal of the material is not too difficult.
- Each of these panel sheets can withstand wind power up to 140 m / hr.
- With the use of this panel is expected to reduce the use of wood as a wall or frame in the column and roof, so it will help create the concept of environmentally friendly buildings.
- This styrofoam panel also helps the concept of energy efficiency. If the panel wants to be applied to the roof to be used as coating materials such as stainless steel, zinc, tiles, asbestos, etc. Certainly these materials will become more durable because Styrofoam will protect these materials in addition to heat-fighting, but also can work to protect against rust and damage. so that the impact will reduce the material turnover too often.
- Styrofoam panels have an important role and different in its use, because it can be used also as an interior and exterior elements in the room.
- Styrofoam is a material that is easily cut and shaped because it has a unique composition. When the panel is cut, its work can be done easily. How to cut it by using a wire that has been heated, so the installation can be more precise.This will reduce the damage to the cutting process, so waste material can be avoided.
