To ensure full airtightness and effective water drainage from the roof slope, Eurovent® VALLEY L should be used as part of a complete system together with:
- other Eurovent® roof valley system components, ensuring precise installation and reliable performance within the valley zone,
- highly vapour-permeable Eurovent® roof membranes (roof underlays / underdeck membranes), protecting the roof structure against moisture and supporting proper water runoff,

The use of complete Eurovent® system solutions guarantees efficient drainage, long-term durability and an aesthetically finished connection in the roof valley area.
GOOD TO KNOW
What is Eurovent® KOSZ L used for?
It is used to form the roof valley where two roof slopes meet. It collects rainwater from both slopes and directs it towards the eaves and gutter system.
What distinguishes KOSZ L?
It is made from longitudinally profiled aluminium sheet with a polyester coating. The profiling improves rigidity and helps create a neat, durable valley detail.
What roof coverings can it be used with?
Its construction makes it suitable for most common pitched-roof coverings. The exact valley detail should always be adapted to the roof covering and roof design.
Why is correct valley installation so important?
A roof valley receives water from two adjoining slopes, making it one of the most heavily exposed areas of the roof. Poor installation can lead to leaks and moisture damage.
What accessories should be used with KOSZ L?
A valley clip and suitable Eurovent® sealing wedges help secure the valley and reduce wind-driven rain and snow penetration beneath the covering.
