floor insulation 

One of the most significant problems with traditional polyester  batt insulation is the risk of air leaks, which can reduce the efficiency of your insulation by up to 70%. Even a small gap of 1% can result in a loss of up to 30% of the insulation's effectiveness.

These gaps can occur when the batts are not properly installed, or over time as the material settles or is disturbed. When air leaks occur, they allow warm air to escape in the winter and cool air to escape in the summer, reducing the overall efficiency of your insulation.

To ensure optimal insulation performance, it is essential to minimize air leaks and gaps in your insulation. This can be achieved by using high-quality batts and ensuring proper installation techniques. However, even with the best materials and installation techniques, gaps can still occur over time, making it necessary to regularly inspect your insulation and make repairs as needed.

In summary, even a small gap in your insulation can significantly reduce its efficiency, making it critical to choose high-quality batts and ensure proper installation to maximize the benefits of your insulation.
