The Viipuri Library's suspended, undulating, acoustic wood ceiling and roof landscape of skylights not only reappeared in Aalto's own work over the next 40 years, they encouraged a concern for form and light in its purest aspects.
To gain more space upstairs and make the height more proportional to the volume, they raised the ceiling from 8 feet to 10 feet and arched it to follow the roof gables.
Where once workers had to bend awkwardly to hold and whack headliners into place on the car's ceiling, a headliner now has sewn-in magnets that keep it in place on the roof's metal frame.
