What is a thermal Break system?

Reinforced polyamide or polyurethane bars that are inserted and mechanically locked in between the inside and outside aluminum profiles to provide an insulated aluminum window and door. More than one thousand times less conductive than aluminum and one hundred time less than steel.
Note all sunrooms, patio rooms, conservatories, solariums unless they are wood have an aluminum frame. Even vinyl rooms have to have an aluminum frame to get the structural strength required for wind and snow loads.

Thermal breaks have become state of the art for green and energy efficient architecture, significantly reducing energy consumption in buildings. The thermal break acts as an insulator and prevents energy loss from the heated inside of the building to the cold outside. The effect of thermal break is also valid for air conditioning saving. It is important to stress the fact that warm climates require higher than other the use of a glass that avoids the solar factor and the heating flows coming from the radiation effects.

Thermal breaks are essential, as they have properties of providing insulation to wood, fiberglass, vinyl or metal frame windows. The thermal break consists of a non-conductive material, such as polyurethane. Aluminum windows with thermal breaks counteract relatively high heat conduction. What a regular aluminum frame does is, it permits excessive heat transfer causing extreme condensation. In addition thermal breaks can have the added benefit of reducing sound transmittance by dampening vibrations. Aluminum windows and frames are low on maintenance. Strong and lightweight in nature, they also resist weathering and are essential for a true year round four seasons room.

Above two are pictures of two different wall systems. Note the one to the directly above has thermal breaks in the aluminum sill that gets anchored to your deck or concrete and the aluminum main support par that goes from floor to ceiling. The thermal break acts as an insulator and stops the heat and cold transfer between the outdoors and indoors of the room.
The wall system above has nothing separating the outside aluminum from the inside. The cold/hot air temperature outside will go behind this vinyl cladding and make contact to the frame. If you heat/cool a room without the thermal breaks, it will condensate and sweat. With moisture comes mold, mildew and rotting. In some climates this will happen weather you heat/cool the room no matter what.
