Adaptable to various architectural demands, this skylight is compatible with roof pitches ranging from 6° to 45°. It goes beyond mere aesthetics to offer sound insulation, protection from UV rays, and is built with safety toughened glass for enhanced security and longevity.

    My bathroom has been completely revitalized thanks to a skylight I bought from this website. The team at Regal Glass was so helpful, and the installation was seamless. Their flat roof windows are a must-have!

  2. Maxwell Adams

    My team and I worked on a house in Bristol and opted for a 1000 x 1000 kitchen skylight. The quality and finish of the product are outstanding. The client was happy and so were we. Highly recommend Regal Glass Group.

  3. Mason Baker

    Adding a large skylight to our kitchen was the best home improvement decision we’ve made. The natural light it brings in has made our kitchen a focal point in our home.
