What does double layered insulation refer to?

Double layered insulation refers to a design that incorporates two or more layers of insulation with staggered seams. This technique is used to enhance the thermal performance of the insulation by minimizing thermal bridging and preventing heat loss. Staggered seams help to create a more effective barrier against air movement, thereby improving the overall energy efficiency of the material.

The staggered configuration allows for a more continuous insulation layer, reducing gaps where air can escape or infiltrate. This design is particularly useful in applications where maintaining thermal performance is critical, as it provides a better seal and improves the integrity of the insulation system compared to simple overlapping layers or a single thicker layer.

As a result, the method of using staggered seams is a common practice in the insulation industry to achieve superior thermal resistance and energy savings.
