Immaculate flush lines to the exterior with the neat square profile to the inside delivers a casement that works in a wide range of properties. It is simple enough for modern architecture but has proportions and options that make it a great choice for more traditional homes too. There are Astragal bars for those who want detail, an alternative fully-flush sash, and cills designed specifically to match the dimensions of timber frames.

Stellar is strong. Its sections can support the weight of large panes of glass without extra reinforcing, allowing individual panes to be larger. Without the complexity of transoms and mullions, views are unrestricted, and more light can flood into your home. Stellar also offers the benefit of equal sightlines for opening and non-opening panes without resorting to adding dummy sashes to the layout.

You can choose almost any configuration of fixed and opening panes, any colour and hardware finish, and the result will be a stunning window that looks fabulous and protects your home.
