VPI manufactures three different window & door systems, each with a particular end market in mind. We have intentionally kept the number of systems to a minimum, and have focused on customization within the product families, instead. VPI has produced over 5,500 different configurations across these three series – whether it be a bespoke, shape window, or a multi-operable, nine panel window, VPI has the engineering and manufacturing capability to fabricate your ideal window.
