Heritage Flush Sash Windows

Heritage uPVC flush sash windows

Our uPVC flush sash windows are excellent when it comes to thermal efficiency and security. They are also virtually maintenance-free, making them a great alternative to timber windows, for example.

Distinguished by the classic lines that fit perfectly into the frame, uPVC flush sash windows look incredible wherever they are installed. They can fit in seamlessly within the frames thanks to their slim sightlines, leaving you without any unsightly blemishes.

The uPVC windows that we install have a strong selection of advantages that they can offer East Midlands homeowners:

• able to retain their elegance for many years while remaining a high-quality window
• noise reduction through a variety of glazing options
• multi-point locking systems fitted as standard for added security
• broad choice of colours and customisation options
• ideal for conservation areas with design in keeping with period properties

Graf Weld: A Seamless UPVC Window Finish

Graf Weld is a cutting-edge welding technology. Unlike traditional welding methods that leave visible corner joints that need cleaning and finishing, Graf Weld creates almost invisible corners with a seamless, smooth finish.

The technology works by pushing the excess material back inside the frame rather than letting it collect on the outside. This process creates a cleaner appearance and produces a stronger corner joint since more of the internal surfaces are connected. The result is a high-precision finish that looks great on coloured or woodgrain uPVC frames.

Graf Weld creates a more sophisticated, premium look that closely resembles timber joinery. This makes it especially suitable for period properties or conservation areas where aesthetics is important. Windows manufactured with Graf Weld technology tend to be more durable and weather-resistant, and without the small grooves that traditional welding leaves behind, there are fewer places for dirt to collect, making cleaning and maintenance simple.

TimberWeld: Authentic Timber Joinery

TimberWeld is a specialised jointing technology that creates the authentic appearance of traditional timber butt joints in uPVC windows and doors. Unlike standard uPVC windows with their telltale diagonal corner welds, TimberWeld produces a clean, vertical butt joint that perfectly mimics the look of classic mortice and tenon timber joinery.

The technology works by using a unique fusion welding method that joins the frame sections together while hiding the welded seam behind a vertical joint. This creates the illusion of traditional timber joinery, but with all the benefits of modern uPVC materials.

TimberWeld is particularly well-suited for heritage-style properties and conservation areas where maintaining traditional aesthetics is essential. The system works beautifully with woodgrain-effect finishes, creating windows that are virtually indistinguishable from timber.
