How Does a Functional Cupola Ventilate

Sir Alexander Fleming stated, It is the one worker who makes the first advance in the subject, the details may be worked out by the team, but the prime idea is due to the enterprise, thought, and perception of an individual.”

A cupola brings in cooler air, while allowing warm air to escape. Our forefathers understood this concept, releasing the hot stagnant air provided longevity to the roofing structure. Printed articles have said, cupolas were the early form of air conditioning.

Cupolas are the small buildings that sit on top of the roof. They are designed to look like a miniature house and are available with windows or louvers, each can provide ventilation. When purchasing a functional cupola. check to see if they are built with screens to keep the bugs out.

From residential barns to grand cathedrals the cupola provides both an aesthetic appeal as well as a functional use. Cupolas add stateliness and a focal point to the buildings upon which they are placed.

Wood is the preferred material as it doesn’t retain heat, so the hot air escapes through the windows or louvered sides. The number of louvers will determine how well they ventilate, the greater the number the better the ventilation. Circulating air to reduce moisture levels and bring in fresh air is ventilation.

The American Institute of Architects estimates that 90% of homes in the United States have unacceptable high levels of moisture.

Insufficient ventilation can lead to moisture problems in the winter and decreased energy efficiency during the summer. If the warm moist air remains in the attic, it causes condensation that will eventually rot the roofs sheathing. In the northern states, when the moist warm air remains in the attic, it can melt the snow causing ice dams on the roof.

Cupolas are placed on the roof which is the optimal place as heat rises to the top. The temperature on the roof is 30-35 degrees warmer than the temperature on the groung?

A functional cupola placed on the roof top allows heat to escape in a natural upward flow through the sides of the cupola. This movement of air eliminates mold, mildew, wood rot and musty odors. Other benefits include overall airflow and light to be filtered to the inside.

When purchasing a cupola for roof ventilation, a hole needs to be cut into the roof. It is recommended that the hole be six inches less than the outer base of the cupola. Using a cupola for ventilation requires metal flashing applied around the base. It is beneficial to work with a qualified contractor when doing this.

The functional role of cupolas for roof ventilation has been replaced in the most part to a decorative architectural accent. Cupolas spice up any building, whether purchased for functional or decorative. They create a country motif to existing or new buildings.

Heating Homes With Stoves and Fireplaces

Hayi Mansoor asked:


Back in history our forefathers performed heating homes with stoves and fireplaces, of course. Times have gone by and as always, good things come around once more as evidenced in the resurgence of stoves and fireplaces to heat our homes.

Wood stoves that are placed in a bedroom, dining room, kitchen or family room are popular once more. Wood is a renewable resource, unlike natural gas, or liquefied propane gas, thus it appeals to many. Also, whereas the old wood stoves were always black, today’s wood stoves come in many colors and thus will blend into any décor. Even styles vary so that they fit into period homes as well as modern contemporary homes, and every style in between.

Modern times have also brought modern innovations, and a wood stove may be equipped with a blower. Blowers disperse the heat from the firebox and into the room quickly and efficiently, thereby saving the occupants from having to rally around the stove for warmth. Instead the entire room is kept cozily warm for you.

Fireplaces were used to warm the homes of our pioneers as well as used for cooking food. Once we learned the theories of heat displacement and such, fireplaces were considered only in the realm of those rich enough to heat their homes through other means and could afford for that heat to go up the flue when they lit their fireplaces!

Today, modern engineering has managed to tame even the fireplace. Not only has it been tamed but fireplaces have become an energy conscious means of heating. This has been accomplished by the use of fireplace inserts. Fireplace inserts allow you to burn wood, but the heat does not go off into the flue to be lost forever. Through the ingenious use of blowers as well as panels of steel, the room can remain very warm and cozy. When additional heat is needed you can simply turn on the unit. Modern engineering has also created blowers that attached to the fireplace insert so that it can even be thermostatically run! Thus heating homes with stoves and fireplaces has been modernized.

If the thought of burning wood either in a stove or fireplace is not appealing to you, you may switch to using wood pellets. These wood pellets are made from sawdust, that would ordinarily have been thrown out when cutting wood, thus they are considered a “green” method of heating. Pressing the sawdust into pellets makes this a clean easy to use product.

Pellet stoves do not create black creosote and thus are very easy to keep clean and work with. Thus, those who are allergic to smoke can easily manage with this type of heating. Heating with pellets also solves a lot of storage problems encountered with wood. Even when a home is heated by natural gas, kerosene or liquefied propane these items must be stored outside the home to prevent accidental fire, but pellets can be stored in the home and are safe to use and keep since they are nothing but compressed wood. Heating homes with stoves and fireplaces is now considered green living!
