One common mistaken belief is that old windows need to be cold and drafty. Expert conservators utilize a number of innovations to bring 19th-century windows into the 21st century.
1. Draught Proofing Systems

3. Acoustic Glass
For residential or commercial properties located on busy roads, restoration professionals can install acoustic laminate glass. This significantly lowers sound pollution without altering the appearance of the window.
