      1. Sophie Reid –

        Our skylight installation was a breeze, and the impact on our living room’s ambiance is just phenomenal. Very grateful for the professional service!

      2. Wesley Olson –

        For our home’s extension, we went with a 400 x 2000 pitched roof window. The difference it makes is incredible, both in light and design.

      3. Reuben Kim –

        Our home’s loft conversion wouldn’t be complete without the pitched roof window from KingsView Glass. Opted for the 400 x 2000 size, and it’s stunning.

      4. Ian MacLeod –

        Superb quality! Installed two skylights in our loft, and they look stunning. The triple glazing is perfect for the British weather, keeping us cosy and reducing noise.

        4 reviews for Pitched Roof Skylight 400 x 2000 mm – Fixed Frameless Triple Glazed – U-Value 0.9

        1. Sophie Reid –

          Our skylight installation was a breeze, and the impact on our living room’s ambiance is just phenomenal. Very grateful for the professional service!

        2. Wesley Olson –

          For our home’s extension, we went with a 400 x 2000 pitched roof window. The difference it makes is incredible, both in light and design.

        3. Reuben Kim –

          Our home’s loft conversion wouldn’t be complete without the pitched roof window from KingsView Glass. Opted for the 400 x 2000 size, and it’s stunning.

        4. Ian MacLeod –

          Superb quality! Installed two skylights in our loft, and they look stunning. The triple glazing is perfect for the British weather, keeping us cosy and reducing noise.
