Flashings for L-shaped combinations
A seamless blend of light, space and modern architecture
Modern attic design increasingly focuses on maximising natural light and visually opening up the space. One of the most effective and functional solutions is to combine a roof window with a vertical window in a knee wall. This combination creates a larger glazed area, improves the view of the surroundings and gives the interior a unique lightness. However, to ensure the overall effect is not only attractive but, above all, safe and tight, a specialized flashing is essential. FAKRO flashings for L-shaped combinations have been designed for the most demanding projects – those that connect the roof with a vertical wall without visible gaps and without the risk of leaks. This solution is aimed at investors and designers who prioritise durability, aesthetics and meticulous attention to detail.
A perfectly seamless connection between roof and L-shaped combination windows
Flashings for L-shaped combinations are responsible for one of the most difficult connections in the entire roof structure – the point where the roof surface meets the vertical window. This area is particularly exposed to precipitation, wind gusts and water accumulation, which is why the role of the right flashing is crucial here. The EUV-B and EUV-BT Thermo models create a tight, multi-layer barrier that directs water away from critical areas and protects the structure along the entire length of the vertical connection. They enable the construction of elegant L-shaped combinations, where the boundary between the roof window and the vertical window becomes almost imperceptible. From the user's perspective, this means greater comfort, more natural light and a feeling of open space.
Easy installation thanks to a design created for special tasks
Combining a roof window with a vertical window is not a standard installation, which is why dedicated flashings significantly facilitate the work of roofers. The system components are designed to precisely connect both windows, ensuring tightness and stable mounting without the need for non-standard flashings. The EUV-B and EUV-BT Thermo flashings are equipped with a set of connecting elements, a drainage gutter and a 120 cm long eaves flashing, which helps to effectively direct water away from the structure. The Thermo version additionally wraps the frame with a layer of insulating material, facilitating the installation of a warm, energy-efficient connection even in difficult weather conditions. The option to use with flat, profiled and high-profile coverings makes the system as versatile as possible.
Versatile use regardless of the roofing
L-shaped combinations can be found in homes with varying aesthetics and construction, which is why the EUV-B and EUV-BT Thermo flashings have been designed for maximum compatibility. They work well on roofs covered with shingles, roofing felt, tiles, profiled sheet metal, and even high-profile coverings up to 90 mm. This means that a single system can be used regardless of the material chosen by the investor. This approach eliminates the risk of mismatching and allows you to focus on the design rather than structural limitations. The flashings effectively direct water away from the windows and provide wind resistance, protecting the critical joint for many years.
Design ensuring safety and protection against external factors
In L-shaped combinations, connecting two different planes always means an increased risk of moisture accumulation or overload. Flashings for L-shaped combinations are designed to counteract these phenomena. A built-in drainage channel removes condensation from the initial covering layer, while sealing wedges prevent dust, leaves and snow from entering. The EUV-BT Thermo version additionally uses flexible insulation material that tightly wraps around the roof window and minimises the formation of thermal bridges.
