Builder’s upstand Designed to mount directly onto a fully insulated and weathered builder’s upstand.

Installation checklist

Use competent roofing contractors and follow the Brett Martin installation guide.
Carry out a suitable risk assessment and fall-protection plan before work begins.
Install onto a fully insulated and weathered builder’s upstand.
Ensure the roof covering dresses up the sides and over the top of the upstand.
Provide a level, obstruction-free bearing surface for the roof lantern.

Important safety note

Roof lanterns and rooflights should be considered fragile during installation. Suitable fall-protection measures should be defined in line with CDM regulations and Rooflight Association guidance.

Where blinds or other fittings are installed in the lightwell, position them as far as practicable from the glass and preferably choose light colours to help reduce thermal stress risk.

Product FAQs

Pyramid Roof Lantern glass options explained

Choosing the right glass specification is important for daylight, solar control and overhead safety. The answers below explain the key differences between toughened and laminated glass options.

What is the difference between laminated glass and toughened glass?

Laminated glass has two layers of glass bonded with a clear interlayer. If the glass cracks, the interlayer helps hold it together. Toughened glass is heat treated to make it stronger, but if it breaks, it breaks into small pieces and falls away.

What is the best glass option to choose?

The best choice is usually a combination of toughened glass on the outer pane and laminated glass on the inner pane. This is often referred to as toughened over laminated glass.

Laminated glass is commonly recommended for the inner pane because it helps remain in place if damaged, reducing the risk to people below. Toughened glass works well on the outer pane, where it needs to withstand weather and temperature changes.

When should I consider blue solar-control glass?

Blue solar-control glass is useful where reduced glare and solar heat gain are required, particularly on south-facing roofs or large glazed spaces exposed to direct sunlight.

4-Pane Glass Roof Lantern
If you’re doing an extension, this is a great finishing touch. Bought for a garden room project to modernise the roof detail. The contemporary profile and slim frame give it a really modern look. Our roofer fitted it onto the upstand without any drama. Packaging was excellent - everything arrived in perfect condition. It feels solid and properly engineered.
