      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.

        Customer Reviews

        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.
