Wax Walls For The Home Save 40 Percent In Energy Consumption

By adding paraffin to plaster, these drywall boards are eco-friendly housing materials.


Researchers from the Polytechnic University in Madrid, Spain, have created a type of drywall that is able to reduce a building’s energy consumption by up to 40 percent. Unlike traditional wallboards that use pure plaster, the energy-efficient drywall consists of paraffin microcapsules in the mixture. The tiny beads of paraffin help the wall absorb heat during the day, and then release it at night. This helps the building stay cool when the sun’s out, and warmer when the temperature drops.

The 1.5-inch board was tested and the researchers found that the material had five times the thermal energy capacity of a regular drywall. The eco-friendly drywall could essentially reduce the building’s energy consumption by up to 40 percent. Researchers are now currently looking to boost the paraffin content from 26 percent to 45 percent.
