Prefab window joinery

With the Wiggers prefab window frame finishing packages, you can finish interior window frames in one go. We supply a complete prefabricated package, consisting of window sills, reveals, end battens and fasteners. Only one fitter needs to work and you have no more sawing waste. The Wiggers prefabricated window frames offer a great solution for renovation projects or new construction projects in both residential and commercial construction.

With the traditional method, finishing window frames takes an average of 2 to 3 man days per house. The joinery material still has to be cut to size and after assembly, a painter does the final finishing touches. Wiggers' prefabricated framing kits are already cut to size and do not need to be painted. They consist of a support (often V313 MDF) and a top layer in the desired final color. We explain the advantages below.

    Underlying technique

    Sheathing is the continuous wrapping of a base material with a plastic film, melamine film, aluminium foil, veneer, paper or even leather. The base material, the backing, is usually MDF, particleboard, solid wood or aluminium. Read more about the technique here.


    't Harde reference

    For an energy-efficient future, 30 homes were renovated in 't Harde by construction company Salverda. RC Panels supplied new facades for this project. We provided the frame panelling. The goal was to install them quickly with little waste. Together with DIB Geveltechniek and RC Panels, we looked for the best solution. Watch the video to see how we did it.
