uPVC Sliding Sash Windows

uPVC sash windows are a type of window characterised by a unique design in which the window panels, or sashes, slide vertically or horizontally in a style reminiscent of traditional Georgian windows. The 'uPVC' stands for unplasticised polyvinyl chloride, a hard, resistant, and low-maintenance material that is often used in the construction of modern windows and doors due to its excellent performance in insulation and durability.

uPVC sash windows are exceptionally energy efficient. This is largely due to the uPVC material, which provides outstanding thermal insulation, helping to keep your home warm in the winter and cool in the summer. When combined with double or even triple glazing, the energy efficiency is further improved, contributing to substantial savings on energy bills and a reduced carbon footprint.

Yes, uPVC sash windows are known for their high levels of security. The material itself is extremely sturdy and durable, resistant to breaking and damage. Additionally, most uPVC sash windows come with multi-point locking systems for added security, making it more challenging for potential intruders to gain unauthorised access.

Yes, at Windows and Doors Company, our sash windows come with the option of double glazing. Double glazing involves having two panels of glass instead of one, with a gap in between that serves as an additional layer of insulation. This not only increases the window's energy efficiency but also provides additional benefits such as reducing noise from outside and increasing the security of the window.

The sash of a window refers to the part of the window that holds the glass panes together. It forms a frame around the glass, and in movable windows, such as those found in sash windows, it is also the part that enables the window to slide open or closed. The sash can be designed to move vertically or horizontally, depending on the design of the window

Sash windows are designed to slide open, either vertically or horizontally. In a traditional vertical sash window, there are two sashes that slide up and down, balanced by counterweights, usually hidden within the window frame. These counterweights, connected by cords running over pulleys, make it easier to open the window and allow it to stay open without additional support. In modern uPVC sash windows, a spring balance system is typically used instead of counterweights, but the principle of operation remains the same.
