Short note: Louvered window components

Short answer

Louvered windows have a frame holding slats at 45 degrees overlapping to shed rain while allowing air and light. Components: frame (head, sill, jambs), stiles grooved for louvres, louvres (timber, glass, aluminium) fixed or movable with 1/3 overlap, rails, operating device (link rod, handle), fittings (hinges, bolts, wire mesh). Used in bathrooms, toilets, kitchens, godowns, factories.

Write a short note on louvered window components with sketch.

A louvered window has a frame in which a number of slats (louvres) are fixed at about 45 degrees to the horizontal, so that they overlap and keep rain out while allowing air and some light to pass.

Components

  • Frame: head, sill and jambs (about 75 x 75 mm), fixed in the wall.
  • Stiles: vertical members of the sash, grooved to hold the louvres.
  • Louvres (slats): timber, glass or aluminium strips; timber louvres about 75-100 mm wide and 10-20 mm thick, glass louvres 5-6 mm thick. They are fixed in grooves at 45 degrees with about 1/3 overlap, and may be fixed or movable by a lever.
  • Rails: top and bottom members of the sash.
  • Operating device: link rod and handle for movable louvres.
  • Fittings: hinges, bolts, and wire mesh to keep insects out.

Uses: bathrooms, toilets, kitchens, godowns and factories.
