Weathervane and Cupola

Weathervane is a device which is used to predict the direction of wind. It is a movable device which is attached to any elevated object mostly roof. They are balanced in such a way that half of its weight is on either side of its axis and the areas exposed to air on both sides are unequal. It minimizes the force of wind and cause vane to rotate.

A Cupola is a dome-shaped ornamental structure which is mounted on the top of large roof. They are also defined as small roofed structures placed on the roof of buildings. It is used to admit light and for ventilation purposes. A cupola is basically a small addition of the main roof placed at the roofline of many barns, stables, garages, gazebos and colonial-style homes.

Weathervane and Cupola
Cupola is mounted over the top of homes, barns, and public buildings etc. vertical line created by cupola is made of brass or copper which are installed to draw attention and to make more personalized touch. A Weather vane draws attention to these vertical lines. Weathervane increases ornamental value and also protects home from storm damage.

Cupolas are generally made up of wood with either a metal or shingle roof. Sides are covered with wooden slats known as louvers which allows light to come in and air circulation. Most of the modern cupolas are ornamental. To measure the required size of cupola you should measure the section of roofline and then make base one inch wide for every foot of roofline.
