UPVC Twin Sash Window

Twin Sash uPVC casement windows from AIS Windows are strong, and will not rot, warp, or require repainting; ensuring that they retain their colour and shape through the years with a minimal maintenance. They combine traditional fly mesh panels with conventional casement windows to provide a classic aesthetic. A grill provision also ensures the security of the window. Twin Sash is a great combination of good looks and high standards of security.
