Other features of the Ultimate Rose sash window include bespoke traditional furniture, A rated as standard, flat putty-style glass lines for authenticity, the slimmest most timber-like sightlines of any window on the market and period astragal bar designs. Ultimate Rose is available in white woodgrain as standard and in a choice of woodgrain foils to suit your taste as well as match the existing style of your home, they are also able to be spray-finished in any RAL colour. To further complete the timber look, a range of astragal bar designs are available as well as many different hardware options to choose from.
