Trade flat rooflights in Daventry

Flat rooflights for Daventry jobs

Rooflights in England should meet the limiting U-value for rooflights in Approved Document L. The glazing can be specified to suit where the job is, and the U-value is stated on your quote.

A flat rooflight should not be laid dead flat. Water needs to run off, so the upstand is built to a slight fall or the unit has one built in.

• Made to your upstand size
• Minimal or hidden aluminium frame
• Toughened outer pane and laminated inner pane
• Double or triple glazed

Measuring tip

Flat rooflights need a fall so water runs off. Build the upstand to a slight slope or use a unit with a built-in fall, and give us the upstand size.

Regulations for jobs in Daventry

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.
