Comprehensive Buyers Guide for the No 9 Silicone Mi-Flash
The No 9 Silicone Mi-Flash is a leading-edge solution designed to deliver a superior seal around pipes where they penetrate roofing surfaces. Manufactured from high-quality, high-temperature silicone, this product is built to endure the rigours of harsh weather conditions, including exposure to ozone and ultraviolet radiation. Whether you are a trade professional or a domestic installer, understanding how this flashing works and knowing the benefits it offers can enhance your installation experience and prolong the integrity of your roofing system.
Key Features and Their Benefits
- High-Quality Silicone: The product is made from premium silicone which not only withstands extreme temperatures but also resists degradation from external elements. This means that once installed, the flashing remains robust and effective for years.
- Quick Installation: The one-piece design ensures rapid installation—typically completed in just five minutes. This can be a considerable advantage when working under time constraints, reducing overall labour costs and minimising disruption.
- Versatility: The design of the Mi-Flash accommodates a wide range of roof pitches and panel configurations. This flexibility ensures that no matter where your pipe is located, the flashing will form a reliable seal.
- Durability: With a temperature range capable of handling 225°C continuously and 260°C intermittently, the product is suited for varied applications, both commercial and residential.
Installation Process
The installation process is straightforward and user-friendly. Begin by accurately trimming the pipe opening to the correct size. It is advisable to lightly lubricate the pipe edge to allow the flashing to slide on smoothly. Once in place, you will need to gently form the flashing to match the curvature and profile of your roof. The provided Fixing Kit, which includes a specially formulated sealant along with screws and caps, is essential for ensuring that the flashing is securely fitted.
Maintaining a meticulous installation procedure is crucial. It is recommended to use three Standard Fixing Kits to achieve a tight, weather-resistant seal. This not only prevents potential leakage but also protects your installation from external elements like wind and rain.
Addressing Common Concerns
Will the flashing withstand harsh weather conditions?
Absolutely. The premium silicone used in the Mi-Flash is engineered specifically for high-temperature environments and exposure to UV light and ozone. This means it maintains its sealing capabilities over an extended period even in extreme weather.
Is the installation process complicated?
Not at all. The design of the flashing allows for a quick, hassle-free installation under normal circumstances. With a few simple tools and the provided Fixing Kit, most installations can be completed in roughly five minutes.
Do I need any additional components for the installation?
Yes, it is important to note that three Standard Fixing Kits are required to secure the flashing properly. Additionally, lubrication may be needed to ensure a smooth fit over the pipe. We recommend checking our optional accessories section where you might find additional aids such as high-performance lubricants and extra fixing kits to enhance the installation process.
Optional Accessories
While the No 9 Silicone Mi-Flash is sold as a complete sealing solution, you may want to consider additional accessories to complement your installation.

These accessories help to refine the installation process and add an extra level of security to your setup.
