Solid is not only the go-to specialist for interior doors, but also for exterior doors and windows. Since 2017, we have been a professional distributor of a carefully selected range of PVC exterior doors and windows, available both as stock products and custom-made solutions.

Our Esterno range has grown into a trusted name, built on three strong pillars: an excellent price–quality ratio, fast availability thanks to large stock levels, and accessible customisation.

We focus exclusively on residential applications. Esterno doors and windows are therefore the ideal choice for professionals and skilled DIYers looking for the best value for money. Thanks to our stock of standard sizes, we can always guarantee fast delivery.

Our exterior doors and windows are made from PVC, a material known for its durability and low maintenance. All Esterno PVC doors and windows feature a clean, modern design and are available in white and anthracite.

Our assortment includes a wide range of PVC exterior doors and various types of windows, such as sliding windows, tilt-and-turn windows, French doors, fixed windows, and tilt windows.

In addition, Solid also offers affordable custom-made solutions. In response to customer demand, we launched a 3D configurator that allows you to design bespoke exterior doors and windows with ease.

As a distributor, Solid acts as a link between production at various manufacturers and our Belgian customers. We work with multiple manufacturers, depending on the specific requirements of each project. To ensure smooth coordination and reliable follow-up, we also maintain a local presence at the factory.
