Reducing Heat Thanks To New Technology For Materials

With the climate change situation, hot summer days have become an obsession, especially for houses in urban areas which have a limited area, lack of ventilation …

Whether a house gets hot or not is determined by three factors from the environment: temperature, air humidity, and wind speed. Therefore, if the current house does not meet the need for heat protection right from the design-construction stage, the application of “fire fighting” measures must affect all three factors. The most common is bringing more nature, water into the house, improving ventilation, or using smart materials …

With nature in the house, or adding water to cool it – a major problem immediately posed is the lack of space. However, this is also the premise for the emergence of vertical garden solutions or convenient frame and truss systems for climbing walls. Sunshades combined with vines are a solution that many people choose. You can refer to the Shading plank product line from SCG’s smart wood material for a reference example. The current lam-climbing systems are constructed simply, easy to install, add to existing buildings, and at the same time create a modern look for the house.

It is also possible to intervene to enhance ventilation and cooling of the house with some special types of ceiling panels. These panels allow the heated air between the roof and the ceiling to escape. “Ventilated ceiling” is a new term that has appeared and caught attention recently.

The application of new technologies, creating smart materials also contributes to reducing heat for the house. An element that is present in almost every home is water paint. However, the effect of each water-based paint product, particularly exterior paint, in anti-heat, is not the same. For example, the cooling technology (KeepCoolTM) in the Dulux Weathershield range of exterior paints can reduce the outside temperature of the wall by up to 50C compared to conventional paints of the same color. Contribute to the reduction of energy used by air conditioners. Not only participating in heat resistance, but new technology also produces paint lines that are resistant to alkali, anti-fading, anti-fouling, UV reflection …

Also, other smart insulation materials can be added inside the wall or under the roof. Insulation sheets lining the roof, cotton insulation for ceilings, walls are capable of reflecting radiant heat absorbed into the house. These materials have an aluminum foil layer to help reflect heat, the plastic part increases durability, resists water condensation, and prevents fire spread … Currently, the insulation panels under the roof are favored because they are easy to install, fewer image influences on the architecture and interior of the house, such as insulation panels and insulating cotton for SCG Staycool ceilings.

The solution to creating more cover

If conditions permit, it is also possible to create an extra layer of “shell” to cover the house, such as coating insulation paint on the roof, hanging more blinds, mobile awnings, racing roofs or sunshades … This needs to be carefully considered to both reduce the summer heat while ensuring the aesthetics of the house!
