Ultrasky Roof Lantern Specifications
A raised roof lantern for a bright kitchen, dining space or orangery. Use this specification summary to plan your order, then match the final layout to your project drawings.
| Product form | Pitched roof lantern with a 25° roof pitch. |
|---|---|
| Frame options | Aluminium or PVCu finishes within the manufacturer’s range; confirm the finishes offered for your order. |
| Manufacturer size range | Up to 4,000 × 5,850mm, subject to design and specification. Online options may cover a smaller range. |
| Ordering dimensions | External kerb dimensions, not the clear hole through the roof. |
| Kerb reference | The installation guide shows a kerb at least 150mm high and 70mm wide. |
| Thermal construction | Thermal breaks at the ridge and eaves; performance depends on the complete specification. |
| Glazing | Confirm the selected glass, tint, safety specification and whole-product U-value on your order. |
Choose the layout before the finish
Position the lantern on a room plan that includes the island, dining table and any ceiling beams. Ask for the proposed bar arrangement so you can judge the view from below. A product photograph is useful inspiration, but your own dimensions determine the final layout.
What to confirm before ordering
Record the width and length with the measurement reference clearly labelled. Confirm whether your quotation includes glazing and any optional components. Agree the kerb and roof-covering detail with your installer before construction, and keep the final order confirmation with the installation guide.
