About Us Vallum Windows was set up in 2012 to build on our prior decades of performance joinery supply from within our related businesses. Our expertise was built on years of experience in joinery manufacture and supply in the Private and Public Sectors, with decades of repeat business built upon a firm customer service ethos, which runs throughout our business. Our products are fully bespoke unless you specify the use of commercially available elements to enable integration with your wider aesthetic and performance plans. Our CNC equipment, laminating and finishing processes ensure the best possible quality of window. All fenestration systems come with the requisite performance certification, backed up with extensive 3rd party testing and certification. Our fenestration solutions team has literally decades of specific joinery industry service and expertise, across many businesses to build on Caudex Vallum’s successful history of glazing and fenestration supply.
