FAQ: What is Structural Silicone?

Q: What is the main purpose of structural silicone?
- A: Unlike regular sealants used just for waterproofing, structural silicone is engineered to bear heavy loads. It physically bonds glass, metal, and other components to a building’s framework, widely used in curtain walls and glass facades.
Q: Can I use regular silicone instead of structural silicone?
- A: No. Regular silicone lacks the tensile strength and high movement capability ( $\pm25\%$ ) required to hold heavy architectural glass panels safely against wind loads and gravity.
Q: Is it safe for all materials?
- A: High-quality structural silicones feature a neutral cure formula. They are non-corrosive and safe for sensitive substrates like coated glass, aluminum, and insulating glass units.
