Ensuring proper waterproofing and air sealing is crucial for maintaining building integrity and energy efficiency. Maintaining the moisture content of internal walls is essential to prevent structural damage and mold growth. Optimal moisture readings for internal walls should range between 40% and 60%.

### Air Sealing

– Gaps around windows can allow moisture and air to enter, leading to energy loss, drafts, and condensation.
– Caulk and sealants are used to fill gaps and prevent air infiltration.
– Regularly inspect caulk and sealants for cracks or wear and repair promptly to maintain a tight seal.

### Waterproofing

– Water penetration around windows can cause rot, mold, and damage to the building envelope.
– Flashing is installed around windows to divert water away from the structure.
– Ensure flashing is properly installed and overlaps to prevent water leaks.
– Window sills and weep holes should be inspected and cleaned regularly to prevent water accumulation.

### Moisture Readings for Internal Walls

– Excessive moisture in internal walls can indicate water intrusion or condensation issues.
– Moisture meters are used to measure moisture content in walls.
–

Readings should be between 40% and 60% for optimal building health.

– If readings exceed 60%, it is recommended to contact a professional to identify and address the underlying cause.

### Conclusion

By effectively waterproofing and air sealing around windows, you can improve energy efficiency, reduce moisture-related issues, and maintain a healthy indoor environment. Regular inspections and maintenance are essential to ensure optimal performance and longevity of your building.
