What is an ornamental fanlight?

An ornamental fanlight is a window above a door that is richly decorated with wood carving. In Dutch it is called a snijraam, a term also used when the decoration is made of another material. In American English it is known as an ornamental transom window.

Features

Application

If you own or are renovating a building with an ornamental fanlight:

  1. Record it first. Photograph and measure the carving before anything is removed, so a woodcarver can replicate missing parts accurately.
  2. Keep water out. Carving has lots of end grain and pockets where water collects. Keep the paint film intact and check putty and sill joints every year.
  3. Repair rather than replace. Rotten sections can often be cut out and pieced in with new timber of the same species, keeping the original.
  4. Think before reglazing. The glazing rebate is often too shallow for standard double glazing. Ask a conservation joiner whether slim double glazing or internal secondary glazing is the better fit.
  5. Check consents. On a listed building, altering such features usually needs listed building consent. Speak to the local planning authority before starting.

Common mistake: burying the carving under thick layers of paint. The detail is lost and moisture trapped beneath the paint rots the timber from the inside.
