uPVC windows are made using Deceuninck profile — casement in their 2500 Traditional Chamfered system, flush casement in their Award-Winning Heritage Flush Sash. Both are priced live at 25% over our real Central Window Systems trade cost, with free delivery on orders over £999 ex VAT. Other materials and styles are shown for browsing — those need a real quote since we don't have costed hardware data for them yet. Made-to-measure orders are 100% at checkout — supply only, no deposit needed.
