NEW Fully Mechanically Jointed Vertical Slider

The Spectus Vertical slider has impeccable proportions. Every component of the system is the right size – a perfect recreation of the original dimensions. This includes the overall front to back depth of 128mm, which makes installation easier, and the style of the deep bottom rail. We offer different sizes of Georgian bar – to suit windows of differing scales – large and small sash profile options and a choice of perfectly sized cills. And for bigger properties, this sliding sash window isn’t scared to go large – there’s a maximum size of 3000mm by 1600mm.

In the past, few authorities would permit the use of PVC-U to replace a timber sash window. Thankfully, that’s changing. Planners have realised that our window’s amazing A+ rated thermal performance and low-maintenance qualities are great for the environment. The Spectus VS is well-known for its authentic appearance, and its use is often approved without further question. Even the most resistant of conservation officers are usually convinced when they see a sample. Now, with the option of a mechanically jointed sash which replicates the appearance of timber window joints, there can be few remaining objections.
