uPVC double hung windows for distributors, installers and building projects. Explore the product, review your configuration and prepare a clear brief for project pricing. Have a window schedule? Start with your sizes, quantities and delivery destination. A double hung window has an upper and a lower sash that slide vertically within the frame. For trade buyers, the opening style is only the starting point. The frame, glazing, hardware and installation details should be evaluated together against the project requirements. Double hung describes the opening style. Double glazing describes the glass construction. Confirm both in your enquiry. Start with the application, then confirm the right configuration. These are buying routes, not separate certified product series. Coordinate dimensions, appearance and installation details with the project drawings and window schedule. Review existing openings, frame conditions and measurement details before specifying replacement windows. Discuss repeat specifications, order quantities, packaging and the technical information your customers need.uPVC Double Hung Windows for Your Projects
