As you can see from the graph below, Thermotech's Fibertherm TM windows have unmatched energy efficiency. Fibertherm TM windows are so efficient that they are revolutionizing the way buildings are designed.
Conventional windows are often drafty for two reasons.
Firstly they leak air. The inherent stability of their fiberglass frames means that Fibertherm TM windows stay as tight as when they are built. The dramatically warmer frame and glazing of Thermotech's Fibertherm TM windows provide maxi mum protection against convective drafts. This means that brighter buildings with more and large,windows can now be comfortable too. Thermotech's FiberthermTM windows overcome the two main drawbacks to passive solar heating, making it easier to capture free heat from the sun.
