Accoya has ended up being an industry favorite since it is chemically customized to be dimensionally steady, implying it does not diminish or swell with the seasons, preventing the typical "sticking" of sash windows.
The Benefits of Choosing Wood over uPVC
While uPVC windows are popular for their low preliminary expense, wood sash windows provide a number of exceptional long-lasting benefits:

To guarantee wooden sash windows last a life time, a proactive maintenance schedule is needed. Unlike plastic windows, wood needs a little quantity of attention to prevent wetness ingress.
Important Maintenance Checklist:Bi-annual Cleaning: Wipe down the frames with warm soapy water to get rid of contaminants and salt (if near the coast).Inspect the Paintwork: Look for cracks or flakes in the paint finish. Little gaps can enable water to permeate into the wood, causing rot.Oil Pulleys: Ensure the pulley wheels are totally free of debris and gently oiled to keep the motion smooth.Check the Cords: Inspect the sash cords for fraying.
