For now, let's talk about the look of your windows. You'll be a little bit led by the style of the house. In Cardiff, we have many older homes, some with bay windows and often, the only choice for windows is the sash window because of the pillars that are already in place. Sash windows are those that lift up and down. Find out more about sash windows.

Casement Windows.

Casement windows are the most popular choice and work well on both modern and traditional homes. Our uPVC casement windows can be either top-hung opening or side-hung opening to suit your requirements, providing excellent ventilation and security. Find out more about casement windows.
