Comparing the roof flashing Chimney Roof WADEX 101 Diameter 180 mm - Roof Flashing for Chimney Pipe with the chimney elbow Chimney elbow WADEX 116180000 90° diameter 180 mm helps clarify the distinct roles these WADEX components play in a chimney system. While both share a 180 mm nominal diameter and serve heating and ventilation installations, they perform entirely different functions: the roof flashing seals the roof penetration against leaks, whereas the elbow redirects the exhaust path.
⚙️ The specifications table below compares the core characteristics, intended purpose, and weight differences between the roof flashing and the chimney elbow to help you understand their practical roles.
| Parameter | Chimney Roof WADEX 101 Diameter 180 mm - Roof Flashing for Chimney Pipe | Chimney elbow WADEX 116180000 90° diameter 180 mm | Practical significance |
|---|
| Product type | Roof flashing / pipe boot | 90° chimney elbow fitting | The flashing seals roof penetrations against weather, while the elbow redirects flue gases inside the duct layout. |
| Diameter | 180 mm | 180 mm | Both items match 180 mm piping standards, but they serve completely different installation steps. |
| Primary purpose | Protecting roof structures from leaks around the penetration | Connecting and redirecting flue gas or ventilation ducts | Selection depends on whether you need to weatherproof the roof exit or shape the routing of the chimney pipe. |
| Weight | 1.8 kg | 6 kg | The lighter flashing is convenient for roof placement, while the heavy elbow requires sturdy support within the rigid flue run. |
◎ The suitability table below evaluates typical user needs and installation scenarios to help you determine which product matches your project requirements.
| Use case | Recommended product | Why |
|---|
| Weatherproofing a pipe penetration through the roof | Chimney Roof WADEX 101 Diameter 180 mm - Roof Flashing for Chimney Pipe | Provides a watertight seal to protect structural roof elements surrounding a 180 mm chimney pipe. |
| Changing the routing direction of a flue or ventilation duct by 90 degrees | Chimney elbow WADEX 116180000 90° diameter 180 mm | Enables directional changes for exhaust paths in residential and light-commercial heating systems. |
The roof flashing Chimney Roof WADEX 101 Diameter 180 mm - Roof Flashing for Chimney Pipe differs fundamentally from the chimney elbow Chimney elbow WADEX 116180000 90° diameter 180 mm because it focuses on exterior roof weatherproofing rather than internal flue redirection. Choose the flashing to secure a watertight seal around a 180 mm pipe on the roof surface, whereas the elbow should be selected when your installation requires a 90-degree turn in the pipe routing.
