Oval Chimney Storm Collar RENOFAST
Description and Purpose
The Oval Storm Collar is a protective element installed on the protruding part of the chimney pipe above the roof passage. Its task is to cover the gap between the pipe and the chimney top cover plate.
Functions of the element:
- Water Drainage: The collar acts like an "umbrella" for the joint. It diverts rainwater flowing down the pipe walls onto the surface of the roof sheet, preventing moisture from penetrating inside the shaft.
- Ventilation: The design allows for a small air gap between the collar and the plate, which ensures ventilation of the shaft and removal of condensate moisture, while reliably protecting against driving rain.
Advantages and Characteristics
- Tight Fit: The shape of the collar perfectly matches the geometry of the oval pipe (180x115 or 220x115 mm), which simplifies the sealing of the joint.
- Corrosion Protection: The element is in constant contact with water, so it is made of high-quality stainless steel AISI 304L / 316L.
- Aesthetics: The decorative collar hides the point where the pipe passes through the plate, giving the chimney a finished, professional look.

Installation Recommendations
- Installation: The collar is put on the pipe after installing the top cover plate, but before mounting the rain cap.
- Sealing: The upper edge of the collar (the contact point with the pipe) must be sealed with heat-resistant or roofing silicone. This guarantees that water will not flow under the collar.
- Completeness: The element is installed underneath the oval rain cap.
