Thinsulate improves the degree to which windows retain climate-controlled air.

Sustainability-enhancing 3M window film

Thinsulate climate-control window film from 3M is a low-emissivity or “low-E” window film that improves the insulation value of a typical single-pane window to close to that of a double-pane window – and the insulation value of a double-pane window close to that of a triple-pane. The film enhances sustainability and comfort and provides fade protection while remaining virtually invisible; it has a neutral appearance that will not dramatically change the look of windows.

Much like upgrading single-pane to double-pane windows to ensure energy efficiency, applying Thinsulate improves the performance of insulation. This climate-control window film keeps warmth in during the winter and cool, conditioned air in during the summer.
