The hot weather has become a priceless thing for us day by day it seems to be getting more and more hot. Therefore, to prevent heat entering the house, it is important not to be overlooked. Many people pay attention to the heat of the roof. But you may overlook the heat from the door and window. Which is a major weakness that heat enters the house directly. Choosing a good Glass Window for doors and windows. It helps to protect from heat from the weather and from sunlight. HomeGuru will help you introduce the properties of various types of Glass Window that will provide comfort inside the house, not as hot as an oven. And of course, it also helps to reduce the electricity cost for cooling the house. It also reduces the amount of heat dissipation from the air conditioner that is part of heating the weather.


Insulated glass is a popular material used for doors and windows. Which has about 5 types to choose from, with different types of Glass Window and that film has differences in features, installation and price. HomeGuru will help solve your doubts, choose the right material for your use and budget.


1. Tinted Glass

Tinted glass is a very popular material in the past. If you still remember each other in the 15-20 era. Last year, almost all houses were equipped with dark tea-colored glass. The principle of reducing the heat of the tinted glass comes from the intensity of the Glass Window shade. The darker the glass helps to cut the glare of the sunlight. Dark colors reduce heat by about one, but they cannot cut off the heat radiation. If you want to reduce the heat well. Therefore, having to use very dark glass which allows less light to pass through, making the house look dark. Plus, the darker the glass, the more heat it will collect. This type of glass costs about 10% more than clear glass.


2. Heat Absorbing Glass

It is the development of heat-insulating glass by adding iron, cobalt or selenium metal oxides that trap heat waves or infrared waves from entering the house. The substance in the glass gives the glass body a green color. But still it looks more transparent than traditional stained glass. Green cut glass blocks up to 50% of heat and costs about 20% more than clear glass, making it a popular glass even today. The disadvantage of this type of glass is that metal substances in the glass will accumulate heat. In some cases, the glass has accumulated so much heat that it breaks itself. So often we see this type of glass as a tempered glass to prevent it being broken.


3. Reflective Glass

This type of glass has heat resistance by reflecting light away. Which is a reflective coating on the glass surface which helps to reflect light, thus helping to prevent heat from entering the house as well. Another advantage of this type of glass during the day will help create privacy. Because during the day we will see the reflection of the outside. But at night the inside is brighter than the outside. It turns out that it can be seen inside while inside it will see a reflection. So we see this kind of glass used in office buildings. It costs 1.5 times more than clear glass, but reflects up to 60% of heat and also creates a modern image for the building. The disadvantage of this type of Glass Window is reflection. Therefore, less light will pass through. It is dark inside and may need to install internal light to illuminate. In addition, the light reflected like a mirror. It may interfere with the area around the building.

4. Low Emission Glass

Low-E (Low Emission) glass is low heat transfer glass. Because the glass surface is coated with silver metal (Ag) (has better properties than iron oxide, cobalt or selenium in green glass to cut the light that will accumulate heat), which this substance has the ability to reflect thermal energy waves. But still has clarity to allow light to penetrate well Silver, in addition to reflecting heat, allows the Glass Window to have a heat transfer value as low as 2-30%, depending on the level of silver coating. However, the silver coating reacts with the weather and turns into a black stain. Therefore, Low E glass is often tapered glass with a coating that is protected inside between two glass panels. Or as a sheet of glass in a system of double insulated glass, low-e-glass is about 2.5-3 times higher than ordinary clear glass.


5. Double Insulated glass

Double insulated glass is the use of two sheets of glass to assemble a set of glass with 2 or more layers. Sometimes low E glass is also used as one of the glass sheets as well. Between each glass there is a gap and sealed all around Inside the compartment for dry air, argon or krypton gas that serves as insulation for up to 90%. It also prevents fogging or condensation on the glass surface that often occurs when the outside and inside temperature are different. Therefore, this type of glass must be used in conjunction with a dedicated frame kit which will be installed at the factory. The size of the front frame can not be modified. Double insulated glass is an innovation that prevents heat, noise and greatly reduces the energy consumption of air conditioners. Therefore, it has a high price and depends on the bloom size Internal gas type and the type of glass used.


All these glasses can be used in residential homes. This will help prevent more or less heat from entering the house. It depends on the type of Glass Window you choose and budget you have. But no matter what kind of glass, it is It still performs better than normal clear glass. In addition to the use of heat shields, HomeGuru recommends additional shading devices in the absence of eaves, such as various types of awnings. Whether it is semi-permanent or as an on – off.

In addition, planting trees to shade helps protect the sun and also provide shade to the house area as well.
