Much like French doors, this beautiful window style features two hinged sashes that open wide, allowing homeowners to fully enjoy their view. Crafted from uPVC, they offer affordability and durability, while the minimal sightlines allow for maximum sunlight to pour into indoor spaces. The result? An inviting, light-filled interior space that feels warm, welcoming, and elegant.
