The Pyramid Roof Lantern is engineered for simple and secure installation on flat or low-pitch roofs, mounting directly onto a fully weathered and insulated builder’s upstand.

Installation guidelines

• Install on a fully insulated and weathered builder’s upstand. The roof covering must dress up the sides and over the top of the upstand, providing a smooth, level bearing surface.
• External upstand dimensions should match the ordered rooflight size (rooflight size = external upstand size) with a tolerance of +20mm / −0mm.
• Minimum upstand height: 150mm.
• Minimum upstand width: 85mm to provide a suitable fixing surface.
• Suitable for upstand pitches from 0° to 5°; for best aesthetics, a 0° (level) upstand is recommended to avoid a “lopsided” appearance.
• These rooflights should be considered FRAGILE. A risk assessment must be carried out to define the measures required to prevent falls through the rooflight, in accordance with CDM regulations and Rooflight Association guidance.

Laminated vs toughened inner panes

• Toughened inner pane supplied as standard.
• Laminated inner pane option improves protection against falling glass in the event of accidental breakage.
• Where blinds or other shading devices are installed beneath the rooflight, they should be positioned as far from the glass as practicable and preferably in light colours to reduce the risk of thermal stress fracture in laminated glass.
