The two-component polyurethane polymers are dispensed into an extruded thermal barrier channel where they react to become a structural insulating polymer. Afterward, the metal web connecting the channel in the extrusion is removed by a debridging machine to produce the final thermal barrier composite structure.
Fill and debridge samples are routinely submitted to Azon for testing in accordance with standards of the American Architectural Manufacturer's Association (AAMA) and ASTM International. Likewise, the quality control test procedures and analysis that are preformed in Altech Custom Coaters Ltd. plant before and during processing ensure the material quality throughout the manufacturing process.
How thermal barriers work in aluminum windows
Aluminum, in its natural state is an extremely durable, stable yet highly conductive material. Climatic conditions on the exterior of a building and wide variations of temperatures (hot or cold) can easily be transferred to the inside of a building through the fenestrations framing if steps are not taken to interrupt this transfer.
When the thermal properties of aluminum are improved dramatic results in energy savings will result. This holds true in both heating and cooling, as it costs as much or more to cool a building as it does to heat it.
All thermal barriers act to eliminate the transfer of outside climatic conditions with reduced condensation as an added benefit. Aluminum window manufacturers now have considerable control over thermal performance of their end-product using the latest designs and glazing enhancements.
Manufacturers have different thermal barrier options to choose from. Perfomance and ease-of-manufacturing are important factors in deciding what type of thermal barrier to use.
