  1. Ethan Jameson

    I’m a builder and recently installed pitched rooflights from Regal Glass for a client in Manchester. The quality and ease of installation were top-notch. My client is thrilled with the natural light in their new loft space.

  2. Liam Pattson

    We went for a large pitched roof skylight in our living room, and it’s the centerpiece of our home now. Regal Glass provided a great service, and the 20-year warranty gives us peace of mind.

  3. Jessica Edwards

    The noise reduction from our pitched roof window is incredible. It’s so much quieter, even during heavy rain.

  4. Ivan Walters

    As a builder, I’ve worked with various skylight suppliers, but Regal Glass Group stands out. Their roof windows have brought countless projects to life, offering unmatched natural light and elegance.
