Traditional Spring Sash Windows - Single
Spring sash windows offer a cost-effective alternative to traditional box sash designs. They deliver classic style, but incorporate a simpler, more compact and modern spring balance mechanism in place of weights and pulleys.
In other respects, spring balanced sash windows display all the benefits of traditional timber sashes, with unrivalled quality, design and engineering.
Double-glazed as standard, they are available with safety glass, obscured glass, acoustic glass or solar control glass. Triple glazing is also available for larger contracts. Twin gasketing ensures reliable weather containment.
