4 reviews for 300x300mm Pitched Roof Window (6°-45°) | Fixed Triple Glazed Skylight | 0.9 U-Value | KingsView

  1. Nathan Byrne

    I chose a small 300×300 mm skylight for the guest bathroom. It’s the perfect size for a bit of natural light without overwhelming the space. Really impressed with the craftsmanship.

  2. Kai Wood

    We chose a 300 x 300 pitched rooflight for our bathroom, and it’s made all the difference. The quality and light it brings in is remarkable.

  3. Jack West

    The skylight works as expected. Nothing special, but functional.

  4. Charlotte Harrison

    The roof window is nice. It fits and lets in light, which was our idea at first.
