Epitome of the K Glazing desgn philosophy
Our Ultimate uPVC sash window epitomises the K Glazing design philosophy – it’s an outstandingly authentic, exceptionally-performing work of art.
Replication with character and charm
Every detail of the Ultimate Rose replacement upvc sash window has been designed to replicate the charm and character of a timber sash window. With slim timber-like profiles and an industry-leading 35mm meeting rail, no other sash window can compete with it on style and authenticity. And with period features as painstakingly detailed as joinery-style mechanical joints, a deep bottom rail, run-through horns and external putty lines, it would take an expert to spot that its uPVC.
Modern materials and techniques
Add to that the host of benefits that come with modern materials and techniques – from energy efficiency and security, through to sound insulation and low maintenance – and you’ll see why Ultimate represents the pinnacle of uPVC sash window design. It’s also why it won New Product of the Year in the prestigious G13 Glass and Glazing Industry Awards.
