Flush Fit Sash Window


Traditional styling with modern performance, this authentic timber window design has been lovingly recreated in uPVC. We fit our uPVC casement windows in Lincoln and throughout the county. 

FLUSH FIT SASH WINDOWS: stylish & contemporary


Flush fit sash windows are a stylish and contemporary option that provides a sleek, streamlined appearance, making them an ideal choice for modern homes and those looking to preserve a traditional aesthetic. The defining feature of these windows is their "flush" design, where the window sash sits perfectly level with the outer frame when closed, creating a clean and minimalist look. This design mirrors the appearance of classic timber windows, making flush fit sash windows perfect for those seeking a heritage look without the maintenance concerns of wood.

 These windows come in a range of colors, finishes, and glazing options, allowing you to personalise them to match your property's unique style. Whether you’re refurbishing a traditional cottage or building a contemporary new home, flush fit sash windows provide a perfect balance of elegance, energy efficiency, and durability.
