How to Beat the heat from sun by Keeping your Roof with cooling effects:
There are many ways to escape from sunny weather in your home or industrial buildings. Here we provide some basic things for you to consider.
Singapore's weather being more hotter on day-by-day.
The summer sun beats down on our roofs, which increases more warm conditions up and radiate that heat into the homes that are closer to the roofs. This results in a considerable amount of heat gain in the upper floors of the building, and we feel uncomfortable, unbearable to stay inside.
The rise in indoor temperatures contributes to greater air conditioning requirements and higher electricity costs, and increased discomfort in areas that are not air conditioned, such as the kitchen and bathrooms. Here are some techniques to drop the temperature by some degrees on your roof.
1. Singapore advises to grow a roof garden (With proper guidance..) One of the best ways to keep the roof with lesser heat is by growing your own rooftop garden with green grass and potted plants and whatever plants are possible to be in your roof. The plant shades the building from direct sunlight while the mud within the potted plants and the lawn absorbs most of the heat that hits the roof and affects our living area.
Before going for a roof garden, make sure that the roof is properly waterproofed so as to prevent any type of water seepage through the external walls or roof slab, which may cause damage to the building.
2. Cooling Paint methods Heat gain can be considerably reduced by Paint the concrete floor with reflective coats or cooling paints or white ceramic or porcelain tiles on the roof. These cooling paints provide good thermal insulation by reflecting the sun’s rays and keeping the living area cooler. A cost-effective way to keep the roof cool throughout summer is by coating the floor with white lime wash. One drawback with using lime wash is that it gets washed away during the monsoon season, hence reapplication is required every summer.
3. Add roof shades The roof slabs are made of concrete, which is a very dense material – it retains heat for a very long time and then transfers it to the indoors. The temperatures can be controlled by creating shade on the rooftop because shaded areas are cooler than the surroundings.
4. Go for heat-resistant flooring Go for flooring materials such as wooden deck tiles or terracotta tiles that do not absorb or transfer as much heat to the lower floors and are comfortable to walk on even during the peak summers.
