Rammed earth walls can be left exposed or combined with other materials like wood, glass, or metal to create striking contrasts. Their natural thermal properties make them an excellent choice for temperature control, while their visual appeal adds character and value to your home.
Phase Change Materials
Phase change materials (PCMs) stand out from traditional thermal mass options because of their unique ability to absorb and release heat at specific temperatures. These materials change from solid to liquid and back again within a narrow temperature range, effectively storing and releasing large amounts of thermal energy.
You'll find PCMs in various forms, including microencapsulated particles, salt hydrates, and organic compounds. They can be incorporated into building materials like drywall, concrete, or insulation, enhancing your home's thermal performance without significant structural changes.
One of the key advantages of PCMs is their ability to maintain a consistent indoor temperature. As your home warms up during the day, PCMs absorb excess heat by melting. At night, when temperatures drop, they solidify and release the stored heat, helping to keep your living spaces comfortable.
PCMs are particularly effective in climates with significant temperature fluctuations between day and night. They can reduce your reliance on heating and cooling systems, potentially lowering your energy bills.
However, it's important to choose PCMs with melting points that match your desired indoor temperature range for ideal performance.
