Why Glass Wool One Side FSK Aluminum Foil Need with 50mm Overlap

Glass wool with one side FSK aluminum foil requires a 50mm overlap for several reasons.

Firstly, the overlap helps to create a continuous barrier against heat transfer and moisture infiltration. The FSK aluminum foil acts as a vapor barrier, preventing the passage of moisture through the insulation material. The overlap ensures that there are no gaps or seams where moisture can penetrate.

Secondly, the overlap enhances the insulation's overall performance by reducing thermal bridging. Thermal bridging occurs when there are gaps or seams in the insulation, allowing heat to bypass the insulation and transfer through the building envelope. The overlap helps to minimize these gaps and maintain the integrity of the insulation layer.

Lastly, the overlap provides added protection against air leakage. It helps to create a more airtight seal, reducing the infiltration of outside air and improving the energy efficiency of the building.

In summary, the 50mm overlap in glass wool with one side FSK aluminum foil is necessary to ensure a continuous vapor barrier, minimize thermal bridging, and enhance the insulation's overall performance.
