- The extremely narrow frame and casement of the new ManuLux® Historic Window clearly measure
less than those of a traditional coupled window, and this offers two decided advantages for
building owners:
Improved appearance. The filigree design of the window is closer to the listed original, allowing the best side of the house to shine through.
- The narrow view and special bar spacers for directing light increase the amount
of light coming into the house by up to 30%. This brightens up the atmosphere and at the
same time that it saves energy!
