Bouwplast uPVC window systems are ideal for creating long, continuous glazed sections in agricultural buildings. These clerestory windows typically combine fixed glazing with Bouwplast uPVC hopper windows, allowing natural daylight to enter while providing additional ventilation when required.
Available with a wide range of glazing options, each system is made to measure to suit your project. Our specialists can also provide daylight calculations to help determine the appropriate window dimensions and configuration.
Bouwplast clerestory windows can also be combined with the LuxAir Daylight and Air Inlet System.
