Trade roof lanterns in Farnham

Roof lanterns for Farnham jobs

Roof lanterns are made to the external size of the upstand they sit on, so the upstand needs to be built and measured before you order.

South-facing lanterns can let in a lot of solar heat. Solar-control glass reduces it, and we can quote both options so you can compare.

• Solar-control and self-cleaning glass options
• Rectangular and square sizes
• Double or triple glazed sealed units
• Made to your upstand size

Regulations for jobs in Farnham

Replacement rooflights and roof lanterns in England should meet a U-value of 2.2 W/m²K under Approved Document L. A lantern in a new extension is covered by the extension's own building regulations approval. Replacing a glazed or polycarbonate conservatory roof with a solid roof usually takes the conservatory out of the exemption, so building control approval is normally needed.
