Standard Bouwplast uPVC hopper windows feature a 58 mm flush frame profile. The frame is designed to provide a good seal against water ingress and can be easily integrated into the building structure.
For even easier installation, the windows are also available as Bouwplast Easy. This version features a 70 mm frame profile with a 21 mm flange around the perimeter, allowing the window to be installed directly into the opening from outside the building.
An integrated EPDM seal along the flange helps provide a secure, weather-resistant fit, reducing the need for additional sealing during installation.
Bouwplast uPVC tilt and turn windows offer residential-quality comfort and functionality for agricultural buildings. They are particularly suitable for offices, ancillary buildings and other areas where additional comfort and flexible ventilation options are required.
Featuring reinforced profiles and secure window hardware, these durable windows are available in a wide range of colours, sizes and configurations.
