TBM Designs

Developing beautiful self-shading window systems using smart materials that can function without using any energy to save energy for individuals and commercial buildings.

TBM has invented InVert™ self-shading windows, which incorporate an elegantly responsive smart materials system within an IGU, requiring no energy, control mechanisms, or human intervention to perform its shading task.
This unique system dramatically reduces artificial cooling needs and greenhouse gas emissions by reducing solar heat gain.

InVert™ Self-Shading Windows

Offer InVert™ Self-Shading Windows

InVert™ Self-Shading windows reduce solar heat gain using thermo-bimetal inside an IGU to lower energy use by up to 15%.

Architect and Inventor, Doris Sung, recognized the dynamic properties of thermostatic bimetal (TBM) due to its ability to curl in response to changing temperatures InVert™ Windows incorporate the TBM material interior to an IGU (Insulating Glass Unit), serving as the core mechanism for the shading effect As the temperature from the sun increases, TBM pieces between the panes of glass change their shape to block the sunlight away from the building, resulting in a shading of the building’s interior When the sun moves away from a respective window and the temperature level cools, the TBM pieces revert to their original shape and position Resulting shading provides a reduction in heat gain of 2-3 degrees Fahrenheit, which can reduce artificial cooling needs by 28-42%, depending on a building's geographical location InVert™ Windows place significant attention on retaining maximum view and day-lighting, allowing for 70% visibility while providing for 90% shading coverage to a building's interior
