When selecting an insulating glass sealant, it is crucial to consider several key properties that can significantly impact performance and longevity. First and foremost, adhesion strength is vital; a good sealant should form a strong bond with both glass and spacer materials to prevent gas leakage and moisture infiltration. According to a report by the National Glass Association, sealants with high adhesion properties can reduce the risk of seal failure by up to 30%, ensuring the insulating performance of the glass unit is maintained over time.
Another important property is flexibility. Sealants must accommodate thermal expansion and contraction to avoid cracking or delamination. A study published in the Journal of Architectural Engineering indicates that flexible sealants can endure movement without compromising integrity, which is especially important in climates with extreme temperature fluctuations. Additionally, durability against UV exposure and weathering is essential, as sealants subjected to harsh environmental conditions can degrade rapidly. Research shows that UV-stable sealants can last up to 20 years longer than their non-UV-resistant counterparts, highlighting the importance of choosing the right product for enduring performance in insulating glass applications.
