Working Mechanism:

Flashing: 

• Properly installed flashing directs water away from vulnerable areas, preventing leaks and water damage. It is often installed where two building components meet, creating a watertight seal.

Trims: 

• Trims provide a finished look to the building exterior and protect edges from weathering. They can also serve functional purposes by covering gaps and joints, enhancing the building's overall weather resistance.

Benefits for PEBs:

Waterproofing: 

• Flashing is crucial for waterproofing PEBs. It helps to channel rainwater away from vulnerable areas, preventing water from seeping into the building envelope and causing damage to structural components or interior spaces.

Durability: 

• Both flashing and trims contribute to the overall durability of a PEB by protecting edges and vulnerable points from weathering, corrosion, and other environmental factors.

Aesthetic Appeal: 

• Trims contribute to the aesthetics of a PEB by providing a clean, finished look. They can also be used to enhance the architectural design and create a visually appealing exterior.

Maintenance: 

• Properly installed flashing and trims can reduce maintenance requirements by preventing issues like water damage and corrosion. This can lead to cost savings over the lifespan of the building.

Longevity: 

• By preventing water ingress and protecting edges from exposure, flashing and trims contribute to the longevity of a PEB, ensuring that the structure remains sound and visually appealing over time.
