Insulation comprises different types of materials such as mineral wool, glass fiber, rock wool, and polystyrene. Each type is effective in reducing heat transfer or sound transmission through a building’s walls and ceilings.
The two main sources of unwanted energy loss are conduction (conduction through thermal bridges at floor level) and convection (air currents caused by temperature differences). By using insulation to reduce these losses, homeowners can save money on utility bills.
Other factors to consider, like insulation’s effectiveness, depending on how the building was constructed; for example, older homes usually have thicker walls that aren’t insulated well because modern construction methods tend to favor thin ones. Finally, it’s important to mention that some energy efficiency aids like power-saving light bulbs and shower heads are more likely to have a greater effect on overall utility costs than insulation.
