PVCu Vertical Sliding Box Sash

With stricter regulations and a growing need for energy efficiency, homeowners are looking for ways to enhance their homes. Upgrading to modern, high-performance windows and doors is a popular option to improve insulation and cut energy use. Older homes often have sash windows with single glass panes that don’t insulate well and lose heat. Traditional timber windows also deteriorate over time and require more upkeep to prevent drafts and cold. For new builds, developers want high-performance windows that match the home’s style and meet strict regulations.
