Constructed entirely of robust silicone, the No. 3 Silicone Mi-Flash 6-102mm (1/4 to 4 inch) - High Temp provides exceptional resistance to weathering, thanks to its unique formulation designed to withstand ozone and UV light. The one-piece design ensures a seamless fit, making installation quick and straightforward, often taking no more than five minutes on-site. The base is engineered to form an airtight seal on various panel configurations and roof pitches, regardless of pipe location.
For optimal results, follow the simple five-step installation process: choose and trim the pipe opening, slide the flashing over the pipe (lubricate if necessary), shape the flashing to match the roof profile, apply the supplied sealant, and use the provided screws and caps for a secure fit. Note that three standard fixing kits are necessary for installation.
