Insulation paint and technical characteristics of heat-insulating paint for walls

What is heat resistant paint?

Heat-resistant paint (or heat-insulating paint) is a type of paint that in its composition has film-forming substances that are able to insulate and reflect sunlight. This type of paint is often painted on surfaces exposed to direct sunlight such as corrugated iron roofs, exterior walls, terraces...

Heat resistant paint has outstanding advantages such as:

Affordable compared to other solutions, less expensive to maintain

The heat reduction effect is very obvious, making the house much cooler

Convenient, easy and fast construction. For residential houses, the owner can do it by himself.

However, not all heat-resistant paints offer all of the above advantages, so you should use caution.

Is using heat resistant paint effective?

Using anti-heat paint effectively is a question of many families. In fact, the effectiveness of heat-resistant paint is highly dependent on the thickness of the paint layer. The higher the thickness, the higher the efficiency. Tests show that with 2 coats, an insulation effect of about 12-25 degrees Celsius can be achieved.

Depends on the specific characteristics of the house. The lower the roof, the more clearly the effect of the paint is felt. The temperature of the surface under the corrugated iron roof can be reduced from 12-25oC or 4-5oC depending on the type of paint.

Is heat resistant paint durable?

The durability of the sunscreen coating depends on the quality and technique of the paint. With average quality and 2-layer paint style, heat-resistant paints have the highest efficiency from 3-5 years. By the 6th year to achieve the same effect as the original, it is best to repaint it again.

In addition, on the market today, there are multi-purpose heat-resistant paints. Paint has other outstanding features such as chemical resistance, waterproofing, protection of walls and roofs from weather and environmental impacts. If using this paint for corrugated iron roofs, it is also possible to reduce noise when it rains.

Which type of heat resistant paint is best?

Old insulation coating technology: has low efficiency, difficult to use because it is easy to layer, it is difficult to stir and mix well. This type of paint causes many difficulties in the construction process such as heavy-handed sweeping, easy to block paint sprayers.

Paint using advanced technology: much higher insulation efficiency, no layering and very gentle stirring, sweeping with brush, rolling or spraying is easy, without clogging the nozzle.

Note when choosing to buy anti-heat paint:

Efficient temperature reduction is the most important feature.

You should pay attention to the cost of use per area, not the price of paints. Many types of paint are expensive, but the cost of use on the area is cheaper than the lower-priced paints.

The ease of use of paint also needs to be noted. Difficulties in construction will cost you a lot of extra time or extra costs.

In the summer, the west-facing house absorbs more heat than the other house directions. Therefore, to make the house in the West still cool, you can refer to the following 5 ways to prevent heat from the West facing house.

Two-layer wall construction:

Experts against heat on the west wall also recommend that families with this direction should build 2 layers of walls to keep the house cooler. This 2-layer wall has a thickness of about 330, two layers of 110-hole bricks are built parallel to each other, ensuring a wall gap of about 10cm. It is this wall slot that is the insulation for indoor and outdoor air. When the outer wall is heated by heat, the inner wall remains cool.

If you don't build a brick wall, you can fill the wall with concrete about 25 to 30cm. With this thickness, the outside temperature can hardly penetrate to the inside, or if there is, much less.

Using insulation for the inside of the wall:

Another way to prevent heat from the west wall is to pay attention to the inside of the wall. You can use insulation materials such as heat-resistant paint, wood paneling, PU foam, insulating film, etc. These materials will minimize the penetration of outside heat into your house. friend.

Use anti-heat paint on the outside wall

Using heat-resistant paint for external walls is also recommended by experts against heat-resistant walls in the West. However, special care should be taken in the selection. Should consult from reliable sources to buy suitable and quality paint. And don't forget to choose colors that absorb less heat. In it, it is recommended to choose lighter tones and use heat-resistant foam paint.

Increase the amount of trees to cover the house

This way of fighting heat for the west-facing wall has never stopped being hot. If any family has conditions on area, they should take advantage and plant trees around the west wall to cool the wall. Can be flower trellises, large plants, climbing plants. As long as you can cover the walls as green as possible.
