uPVC Sash Window Replacement


SJB Ultimate uPVC Windows

SJB Ultimate uPVC Windows have been designed to perfectly replicate the charm and period character of your existing timber sash windows. Using slim timber-like profiles and industry leading 35mm meeting rail no alternative sash window can match up to it’s style and authenticity. It would take a real expert to spot that an Ultimate window is actually PVC as they come complete with detailed joinery style mechanical joints, run-through horns, a deep bottom rail and external putty lines.

The Ultimate range also will provide you with the benefits that modern materials and techniques offer as standard, that includes high energy efficiency and security, plus low maintenance and reduced sound pollution.

The SJB Ultimate meeting rail is the slimmest on the market today, it’s almost 10mm slimmer than the Heritage meeting rail and leads the way in authentic uPVC sash window design. And by designing our own we have removed the exterior interlock line making the meeting rail look exactly like a single solid piece of timber. It’s authenticity at a maximum level.

There aren’t any welds on an Ultimate window, everything is fully mechanically jointed. Using custom jigs, blocks and brackets every join on the frame and sashes is a finished butt joint, exactly as you would find on a timber frame. Furthermore frame joints are horizontal while the sashes are joined vertically, this means added strength and accurately mimics original timber sash construction. Such attention to details is what sets the Ultimate range apart from it’s competitors.

The Ultimate window also features a bespoke run-through horn which is topped off with a flush fitting cap, the end result of which is the most authentic run-through horn we believe you will find.

With flat putty style external glass lines and subtly moulded internal ones fully matched on the astragal bars, triple sealed concealed brushpiles, discreet silver or white gaskets and an authentic deep bottom rail, these windows offer the slimmest sightlines available.

The SJB Ultimate window comes in white ash woodgrain finish as standard, from which you can then choose plain white, cream woodgrain, golden oak and rosewood. We can also factory spray the windows in any RAL colour you desire, both externally and internally.

The SJB Ultimate window is specifically designed to be the most authentic uPVC sash window available, and a final benefit? It will never need painting again!
