Air-tight flashings
Accessories ensuring a tight connection between the vapour barrier membrane and the roof window, protecting the thermal insulation against moisture.
Guaranteed tight insulation around roof windows
Air-tight flashings are an essential element of roof window installation, responsible for maintaining the integrity of thermal insulation. Their main task is to create a barrier that prevents warm and humid air formed inside the room from penetrating the insulation layers around the window. Proper protection of this area is crucial for securing the building’s energy efficiency and the comfort of its occupants. Joint areas are particularly critical in any roof structure – this is where thermal bridges most often occur, leading to heat loss and moisture in the insulation materials. Air-tight flashings eliminate this risk by sealing the connection between the vapour barrier membrane and the roof window. They create a tight barrier that keeps the insulation wool in optimal conditions, protecting it from moisture and deterioration of its thermal insulation properties.
Insulation protection and user comfort
Damp insulation quickly loses its thermal performance, which translates into higher heating energy consumption and reduced indoor comfort. Air tight flashings effectively eliminate this problem by protecting the insulation material from contact with humid air. This type of protection also prevents the growth of mould or fungi that could otherwise develop in damp roof layers. As a result, not only is energy efficiency improved, but also the hygiene and durability of the entire roof structure. Flashings are installed from the room side and their installation does not require complicated tools. It is a quick and aesthetic solution that facilitates proper installation. In combination with other insulation accessories, they create a complete system that effectively protects the interior of the house against heat loss and excessive moisture.
Durable construction and suitability for various window types
Air-tight flashings are made of high-strength polyethylene film. This material is resistant to mechanical damage, ageing and moisture, ensuring long service life and reliability. The flashing edges are designed for easy insertion into the frame, which facilitates installation and ensures a tight connection with the roof window frame. The range includes solutions suitable for both traditional roof windows and windows installed in flat roofs. This makes them suitable for use in a variety of building types – from single-family homes to commercial buildings and public buildings. Various sizes and variants allow for the flashing selection suitable for any roof window model.
An integral part of the insulation system
Air-tight flashings are often used together with other insulation accessories, such as XDP insulation kits. This combination creates a coherent and tight insulation that protects the roof window from both the outside and inside. This comprehensive protection eliminates the risk of leaks and ensures stable energy performance of the entire roof.
