Key Features and Their Benefits
1. Premium Material Use:

Installation Process
A successful installation is crucial for the performance of any chimney accessory. Below are detailed steps for installing the TWPro MB Storm Collar:
- Preparation: Ensure that the area around the roof flashing is clean and free from debris. The installation surface should be dry to allow the silicone sealant to adhere properly.
- Positioning: Secure the storm collar about 25mm above the highest point of the flashing. This recommended spacing allows for optimal water runoff and effective sealing.
- Sealing: Apply a robust bead of high-quality silicone around the top edge of the collar. This step is critical as it ensures that the unit becomes completely watertight, preventing any water from seeping behind the collar.
- Final Check: Once installed, conduct a thorough inspection to confirm that all edges are well-sealed and that there is no gap in the positioning. Test the installation under simulated conditions to ensure its robustness.
