Velux Windows

Velux logo for loft conversion Portsmouth

Welcome to our dedicated Velux window website page, where we delve into the world of innovative roof windows that have revolutionised loft conversions and Architect interior design. Velux windows have a rich history dating back to the 1940s when the concept was first introduced by Danish engineer Villum Kann Rasmussen. Over the years, Velux windows have evolved from simple roof openings to sophisticated designs that enhance natural light, ventilation, and energy efficiency in homes worldwide.

Today, Velux offers an extensive range of window types and sizes to suit various architectural styles and project requirements. From traditional center-pivot windows to top-hung and balcony roof windows, each design caters to different aesthetic preferences and functional needs. With options for manual or electric operation, as well as additional features like blinds and rain sensors, Velux windows provide versatility and convenience for homeowners.

Incorporating Velux windows into loft conversion design has become a popular choice for maximising space and enhancing the overall ambiance of the room. Whether it’s adding a skylight to illuminate a cosy loft conversion bedroom or installing larger roof windows to create a bright and airy living area, Velux windows seamlessly integrate into loft conversions, transforming once dark and unused spaces into inviting and functional rooms.

Join us as we explore the world of Velux windows, from their fascinating designs to their applications in loft conversions and beyond. Explore the brochures on this page and discover how these innovative windows can elevate your living space and bring the beauty of the outdoors inside.
