Great to see you again! Thanks for visiting!
Timberline Geodesic Homes have been constructed in all 50 states and many foreign countries. Built in all types of climates, Timberline Geodesic Homes offer unmatched energy efficiency. Timberline Domes use 30% less surface area to enclose the same amount of volume as a box type structure. This means there is less area for heat to escape or outside air to penetrate. In addition, the spherical shape of a geodesic dome provides for natural and efficient interior air circulation. The natural aerodynamics of the dome means that cold air blows around the home instead of hitting a flat wall and penetrating to the inside.
Our reputation has been built on quality products and service. We look forward to helping you turn your dream into reality.
Why do geodesic structures save on building materials?
The primary factor affecting efficient use of materials and energy in a structure is its shape. Think of a soap bubble. A sphere represents the smallest amount of material surface area needed to enclose a given volume of space. A divided sphere becomes one of the most efficient shapes known to enclose a given floor area.Why do geodesic structures conserve energy for heating and cooling?
The answer again lies in the shape of the geodesic structure. The lower the total outside surface area (walls and ceilings) the greater the efficiency in energy use for heating and cooling. A dome has approximately one-third less surface area to the outside than a box-style structure. The amount surface area exposed to the elements has a much greater impact on energy efficiency than insulation values. Additionally, heat loss from the foundation of a home is generally more dependent on perimeter length than floor area. A dome, having a smaller perimeter/square footage ratio than a box-style home, will lose less heat from the foundation.
Efficient airflow inside that dome adds to the energy savings further; the curved surface of a dome provides a natural circulation of internal air. Outside the dome, the shape of the dome provides an aerodynamic effect; wind passes over the dome with less resistance. In comparison, a box-style structure provides a flat barrier to wind, creating positive wind pressure with air infiltration on one side, and suction, or negative wind pressure, with internal air exfiltration, on the opposite external surface.
