Design, Durability, and Construction
A well-designed chimney flue system plays a critical role in the overall safety of your property. The TWPro MB Storm Collar Ø 175 is specifically engineered for this purpose, with a robust build that stands up to the harshest weather conditions. The outer layer of 304 grade stainless steel is chosen for its resistance to oxidation and corrosion, while the inner layer of 316 grade stainless steel offers superior strength and durability. This dual-metal approach not only enhances the lifespan of the product but also ensures that it functions optimally in environments exposed to moisture and temperature fluctuations.
Installation and Maintenance
Proper installation is essential to harness the full benefits of the storm collar. It is recommended that the collar be installed at least 25mm above the highest point of the flashing to achieve a secure and effective seal. During installation, the following steps should be observed:
- Carefully measure and mark the installation point on the roof.
- Secure the collar in position, ensuring that it aligns perfectly with the flue.
- Apply a continuous bead of high-quality silicone around the top edge to eliminate any gaps.
- Fasten the components with the provided locking band to maintain the required clearance from combustible materials.
Regular maintenance is minimal but crucial. Check periodically to ensure that the silicone seal remains intact and that there is no visible wear on the stainless steel surfaces. This approach ensures long-term performance and continued water-tight protection for your chimney system.
Addressing Common Concerns
