Accessories for roof penetrations
In this category, you will find a wide selection of accessories for air exhaust and intake – including durable Lindab ventilation solutions, roof flashing components, and flexible Systemair accessories. The focus is on functionality, airtightness, and ease of installation for all types of ventilation systems.
Lindab Ventilation – AGIS, GISOL & WKR rain collars
Lindab is behind some of the most widely used ventilation components in both residential and commercial projects. Products like Lindab AGIS and Lindab GISOL are designed for efficient airflow and airtight duct system sealing. Gisol Lindab components ensure proper insulation and reduced condensation.
Rain collars of the WKR type are mounted directly onto the duct to prevent water ingress at the roof transition. The installation involves placing the rain collar over the duct, securing it with tensioning screws, and sealing it to the pipe with a suitable sealant such as Sabetofix. We offer both mounting adhesive and sealant compounds.
Lindab rafter brackets are flexible connectors between the roof and the ventilation duct, covering angles from 0° to 60°, making them ideal for both flat and steep roofs – including 25-degree and 45-degree brackets.
Systemair flashing kits – sizes & roof angles
If you are working with roof-mounted ventilation exhaust, Systemair offers a series of flashing kits for roofing felt and tile roofs – available in standard sizes and compatible with a wide range of roof pitches.

Our rafter bracket selection covers common roof angles – from flat (0°) to steep (up to 60°) – including 25-degree and 45-degree options, offering flexibility and secure installation across many roof types.
