uPVC windows are low-maintenance, energy-efficient window frames made from unplasticised polyvinyl chloride, designed to resist rot, corrosion, and weathering.
Resurgence is the flush sash window for the 21st century, with the charm of a traditional timber window and all the benefits of modern energy efficiency.
Designed to replicate a traditional timber window with its multi-chambered design, its external flush finish eliminates the telltale overlap of standard uPVC windows.
The design features a double-rebated weather seal and patented co-extruded bubble gasket which eradicate the unsightly external seals normally found in replica timber windows and ensure a draught-free, weatherproof fit. The ultimate in modern thermal efficiency, with none of the ongoing maintenance.
Woodgrain Finished Options
A wide range of woodgrain and coloured-foil options are available for either or both internal and external faces or even differing frames.
Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.
