Why is it necessary to insulate the house?
Vietnam’s climate, especially the North, is not only hot in summer, but also sultry. The sun and temperature from the environment, once penetrated into the house, will be difficult to escape, smoldering in the concrete wall for many hours, so even in the evening, when the sun is off, it is difficult to feel cooler.
At this time, many families will turn on the air conditioner continuously to combat the heat outside. The effect is real, but this way is actually not optimal because the air conditioner always has to work harder to compensate for the constant amount of heat entering the house, which is extremely wasteful of electricity. When the air conditioner has to operate at full capacity, it is also more prone to damage and degradation.
Turning on the air conditioner has a really good cooling effect, but it is not the optimal way to reduce the heat in the house.
That’s why outside insulation solutions for houses were born. Basically, they can be a layer of paint, a corrugated iron roof or simply a film glued to the glass door. Because of the use of insulating materials and materials, they can limit heat penetration, effectively reducing from a few degrees to several tens of degrees. As a result, the indoor temperature will always be passively cooler without depending on air conditioning or any other electrical cooling method.

Currently, you can easily find and buy 4 types of insulation materials below, depending on the quantity and brand, the price fluctuates but they are not too expensive, just need to invest a few million dong and bring long-term effects. . The heat in the house decreases, the air conditioner does not have to work hard, reducing electricity bills and good for the health of family members.
Insulation Film
This is the easiest way to reduce heat in the house, the effect is clearly visible in apartments with glass doors and windows facing out. Insulation films are composed of multiple layers such as metal, nano and ceramic coatings to reduce heat transfer as well as harmful UV rays from outdoors to indoors. Films coated with dark colors can also reduce the intensity of sunlight, contributing to a very significant reduction in heat, which can be up to about 10 degrees Celsius during peak hot days.

The advantage of this dish is also in the very affordable price. Depending on the material, brand and heat/UV resistance, the price can range from 200,000 VND to 400,000 VND for Made in Vietnam products. Those who prefer to use foreign products can choose products from brands such as 3M, NEXGARD of the US and Korea, the price is higher but the insulation ability also increases.
Insulated double glazing
Insulated glass looks just like normal glass at a glance. It has the ability to insulate because it is made up of 2 layers of glass, in the middle is injected with inert gas to limit heat transfer and noise from outside to inside. In addition, the product also uses special glue to prevent inert gas from escaping and desiccant particles to remove water vapor and fog from clinging between the two layers of glass.

However, with large glass doors and windows, users will have to apply extra layers of shatterproof film to ensure safety. Adding the two costs together, this is an expensive method, although very effective, it can be reduced to more than 10 degrees Celsius depending on the type.
Insulation paint
The way insulation works is to reflect light and heat from the environment. Therefore, the heat will not penetrate the walls and layers of material. The beauty of insulation paint is that the hotter it is outside, the higher this reflectivity is.
Paint insulation costs are not very high but effective.
Many paints are advertised as being able to reduce 5-8 degrees when the outdoor temperature is 45 degrees, increasing to 12-20 degrees when the outdoor reaches 60 degrees Celsius. As a result, the indoor temperature is also significantly reduced. After all, the air conditioner doesn’t need to work much to maintain a cool level.
In addition, the advantage of insulation paint is also a moderate price, many lines are only about 500,000 VND – 1,000,000 VND / 5L. Families just need to paint on the walls facing the sun is enough, no need to repaint the whole thing.
Insulated corrugated iron roof

Anyone who uses a roof to cover the terrace to prevent heat should always invest in heat-insulating corrugated iron, the heat reduction effect is not inferior to the three methods above. This type combines many layers of materials together, thicker to limit heat penetration, capable of blocking more than 90% of the heat from the sun, reducing noise when it rains without being expensive.
