Sealant Removal & Replacement FAQs:
What role do sealants play in the building envelope?
Sealants play a critical role in the building envelope by protecting joints, transitions, and penetrations against water intrusion, air leaks, and environmental deterioration, especially in New England's harsh climate.
What are expansion joints and why are they important?
Expansion joints are engineered gaps in building exteriors or structural elements that allow for controlled movement caused by temperature changes, moisture, or settlement. They protect commercial buildings from cracking and water intrusion, especially in New England climates.
How do sealants and joints fail over time?
Sealants and joints fail over time due to weathering, UV exposure, thermal movement, moisture, improper installation, and aging. Regular inspection and maintenance are crucial for long-term envelope performance.
How often should sealants and expansion joints be replaced?
Sealants and expansion joints on commercial buildings typically require replacement every 5 to 15 years, but this varies based on exposure, building use, and regular inspection findings.
What materials are used for commercial sealants and joint systems?
Commercial sealant and joint systems typically use materials like silicone, polyurethane, preformed foam, and hybrid sealants. The specific choice depends on factors such as movement capability, exposure, substrate compatibility, and long-term performance needs.
