What Are Casement Windows?
uPVC casement windows are one of the most popular window styles installed across the UK thanks to their clean appearance, excellent ventilation and versatile design options. Hinged at the side or top, casement windows open outward using secure modern locking systems and easy-to-operate handles.
At Lion Guard Windows & Doors, we supply and install premium made-to-measure casement windows throughout Swansea and Carmarthenshire.
